21 Page of Definitions and abbreviations.. Definitions For the purposes of the present document, the following terms and definitions apply: RCT Test System (RCTT): System that connects to the UUT and which is responsible for the initiation, execution, termination and verdict assignment of the different test cases covered in this document. Test System Controller: part of the RCTT intended to control, configure and synchronize the different instruments involved in the test setup and which is responsible for the execution the different test scripts on the UUT. Signaling Unit: Part of the test system behaving as the UUT counterpart, intended to provide the necessary signaling (i.e., protocol) capabilities at the MAC and PHY level to trigger the necessary UUT functions for all possible test scenarios. This includes but is not limited to:. Connection procedures between the Test System and the UUT (burst. Allocations, Initial Ranging, service flow establishment, etc.). Power control procedures. Remote configuration and reporting mechanisms. Invalid behaviour simulation (frequency errors, Round Trip Delay (RTD),. NAK signals, etc.) Vector Signal Analyzer (VSA): part of the RCTT responsible for the advanced signal processing over the RF signal including but not limited to: time and frequency domain analysis, frequency error measurements, constellation measurements, etc. Vector Signal Generator (VSG): part of the RCTT responsible for any additional signal generation in the test setup (for example, interferer signals) Power Meter: part of the RCTT responsible for accurate power measurements (this element may be replaced by the VSA if enough measurement accuracy is ensured).. Abbreviations For the purposes of the present document, the following abbreviations apply: BER Bit Error Rate BI Invalid Behavior BO Inopportune Behavior BS Base Station BSE Base Station Emulator BV Valid Behavior BWR Bandwidth Request CA Capability CINR Carrier to Interference plus Noise Ratio CP Cyclic Prefix CQI Channel Quality Information CQICH Channel Quality Information Channel CS Channel Spacing CTC Convolutional Turbo Code 00 WiMAX Forum Doc Number: WiMAX XX xxx xxx v.0.0

23 Page of 0 0. Measurement system.. General requirements The general block diagram, naming the test interfaces, is shown in Figure. The block diagram describes the main system components and interfaces conceptually, without specifying the implementation. The manufacturer shall make the signals in the listed interfaces available during testing for measurements. In the figure, the following abbreviations are used: A: Antenna interface M: MAC interface When the antenna interface is not accessible for conducted testing, the vendor may supply an antenna coupler for the interface. In this case, the vendor shall be responsible to calibrate and certify the coupler loss and frequency characteristics. Some test procedures assume that the counterpart for the UUT, denoted Signaling Unit (BSE), Signaling Unit (MSE) or Tester, has some additional features not mandated by [], [] and []. These features are solely there to aid the test procedures. Typical tester functions are: capability to eject gating signals for the measurement instruments, special software for requesting a special behavior of the UUT. The Tester also has significantly better and known output signal quality than the UUT. The requirements of the Signaling Unit (MSE) and the Signaling Unit (BSE) are outlined in Appendix. The diagram in Figure is bi-directional and assumes functioning paths in both the downlink and uplink.

27 Page of Test Procedures.. General statement for all tests. Test procedures are provided below for all mandatory tests.. In any test the losses for all RF elements will be considered and compensated for. This procedure will be called setup calibration.. If used, the Packet Generator is configured accordingly to the message(s) sent, the type of modulation used and the data packet rate specified in the test procedure.. The measurement uncertainty for all RF level based measurements should be added to the tolerance for absolute power measurements.. With the exception of the tests that test the ranging parameter, initial ranging should be completed, prior to a measurement being recorded.. The meaning of the words "receives data correctly", as stated in the test procedures, is defined in Appendix..

39 Page of MS-0.: MS receiver RSSI measurements The purpose of this test is to verify that the MS receiver, when requested by the BS to report the RSSI measurement, can meet the accuracy requirement defined in IEEE0.-00, IEEE0.e-00, and the Mobile System Profile. Such a requirement is expected to be satisfied for the entire RSSI range and under typical channel/interference conditions.... Introduction A BS could request the RSSI measurement from a MS via REP-REQ and the MS shall report it via REP-RSP. In the REP-RSP message, the RSSI report shall follow the TLV encoding format with a type value of. and a length of bytes (one byte for the mean and one for standard deviation). Section... ( RSSI mean and standard deviation ) of IEEE0.e-00 specifies the quantization rule if RSSI is reported via REP-RSP messages: Mean and standard deviation statistics shall be reported in units of dbm and db, respectively. To prepare such reports, statistics shall be quantized in db increments, ranging from 0 dbm (encoded 0x) to dbm (encoded 0x00). Values outside this range shall be assigned the closest extreme value within the scale. The message time index is incremented every frame. The reported RSSI value shall be an estimate of the total received power of the frame preamble of the segment of the connected BS. Section... of IEEE further states: The method used to estimate the RSSI of a single message is left to individual implementation, but the relative accuracy of a single signal measurement, taken from a single message, shall be +/- db, with an absolute accuracy of +/-db. This shall be the case over the entire range of input RSSIs. Also during handover related RSSI reporting, a BS may request a scan report including RSSI measurement from a MS via MOB_SCN-RSP, and the MS shall transmit a MOB_SCN-REP message constructed according to the requests indicated in the MOB_SCN-RSP. A different range and quantization are specified in Section...0 ( Scanning Result Report (MOB_SCN-REP) message ) and... ( MS HO Request (MOB_MSHO-REQ) message ) of IEEE0.e-00: The BS RSSI mean parameter indicates the Received Signal Strength measured by the MS from the particular BS. The value shall be interpreted as an unsigned byte with units of 0. db, such that 0x00 is interpreted as 0. dbm, an MS shall be able to report values in the range 0. dbm to 0 dbm. The measurement shall be performed on the frame preamble and averaged over the measurement period. The RSSI measurement in both cases should be the received power from only the particular BS that transmits its preamble from its associated segment....

The tester should be able to adjust the received power from both the serving BS and the neighboring BS to their appropriate levels, respectively. The power should be the average only during the preamble. Measurement of the preamble power may be needed for setting the power level. In this case, a time triggered measurement is needed. This can be achieved either using an RF rise triggering, or using an external trigger signal from the tester. The latter may be more reliable.. Even though the RSSI measurement is based on preamble, the transmit BS signal should still reflect the normal operation condition to avoid MS misbehaving.

41 Page of Test procedure Two test scenarios are specified to reflect the two typical operation conditions. Scenario- is the case when there is negligible interference on the segment of the desired BS, and scenario- is the case when there is non-negligible interference, typically from nearest neighbors. In the latter case, the RSSI measurement should correspond to that of the segment of the connected or the particular BS, as required by the standard. Scenario-: No interference on desired segment In this case, the interference BS illustrated in Figure is absent. The serving BS preamble are determined as segment ID=0 and cell ID=0. Test procedure: Set the test center frequency to middle channel of declared band class according to Appendix. MS power on and perform network entry. Perform a series of BS/MS message exchange to enter the operation condition of BS transmitting REP-REQ and MS transmit REP-RSP. For each RSSI test points in Table (see Note ), set the signal power level at A Ms is at the level specified according to the table. Signaling Unit (BSE) requests RSSI of the desired BS via REP-REQ issued at an interval of 0 frames (see Note ). Record the RSSI feedbacks in REP-RSP as responses to REP-REQ Record 00 reports for each test point Repeat the test procedure for the low, middle, and high channel of the declared Band Class. Table. RSSI test points and levels (scenario-) Test points RSSI test levels (dbm) Note RSSI test range and test points: In the REP-RSP message, the RSSI report is quantized to db for a range between -0 to - dbm. However, for the most robust MCS (QPSK rate-/ repetition-), a RSSI lower bound of -00.dBm is needed for AWGN channel (assuming db NF and no implementation loss) for a 0MHz receiver. Given the preamble is boosted by.db relative to data, the corresponding RSSI during preamble will be around -dbm (0MHz) and -dbm (MHz). Considering a maximum of db implementation loss allowed for sensitivity, the test uses - 0dBm as the lowest RSSI test point. Note Time interval allowed between two reports: With an averaging factor of / chosen to reflect desired RSSI averaging in typical operation, instantaneous measurement older than 0 frames has only a contributing weight of WiMAX Forum Doc Number: WiMAX XX xxx xxx v.0.0

42 Page of Scenario-: Single interfering BS (same segment ID, different cell ID) In this case, the interference BS illustrated in Figure is active. The serving BS preamble sequence is kept the same (i.e., segment ID=0 and cell ID=0), and the neighboring BS s preamble is determined by a segment ID of 0 and a different cell ID (cell ID=0). The interfering BS is required to be synchronized in time (both symbol and frame) and in carrier frequency. Test procedure: Set the test center frequency to middle channel of declared band class according to Appendix. Set the desired BS signal power level at the first test level in Table 0. With the neighboring BS off, power on the MS and perform network entry. Perform a series of BS/MS message exchange to enter the operation condition of BS transmitting REP-REQ and MS transmit REP-RSP. Tester requests RSSI of the desired BS via REP-REQ at an interval of 0 frames Record 00 RSSI reports. Compute the mean "RSSI_no_int". Turn on the neighboring BS and adjust its signal level to the three corresponding test levels in Table (see Note ). Record 00 RSSI reports. Compute the mean "RSSI_int".

The test will verify that the MS estimates the RSSI from the particular BS, not for example the total signal power.... Compliance requirements The test verdict will be set as follows (example):.- pass : a.- In scenario, all RSSI measurements taken should be within +/-db of the expected RSSI, and b.- In scenario, the RMS error is lower or equal than db, and c.- In scenario, the difference (RSSI_no_int - RSSI_int) is lower or equal than db.- fail verdict if any the following conditions are verified: 00 WiMAX Forum Doc Number: WiMAX XX xxx xxx v.0.0

Configure the attenuators so that the average powers at the MS antenna input are according to Table. Note: the power of each source can be measured at the combiner input and the combiner loss can be compensated, and there is no requirement on the accuracy of such compensation, as long as the ratio between the signals is maintained as in Table. Step. After preamble, the BSs all use major groups Step. Configure the MS UUT to use no averaging (i.e., alpha=) and CQI feedback per frame Step 0. The Signaling Unit (BSE) receiver (connected to the UUT transmit antenna) should receive the CQI reports and report to the test utility synchronized to frame numbers. The BSE receiver should also be able to detect a case that the MS failed to transmit CQI in a certain frame (e.g. by power measurement on the CQI) and mark the report as invalid. Test Procedure: Step. Turn on the MS UUT and let it settle for a few seconds Step. For each scenario specified in Table set the power levels according to the table. Step. After setting the power levels, let the UUT settle for few seconds. Step. The following steps are repeated for reuse and reuse reporting.

52 Page of MS-0.: MS receiver adjacent and non-adjacent channel selectivity The purpose of this test is to verify that the MS receiver can meet the Adjacent and Non-adjacent Channel Selectivity defined in IEEE0.-00, IEEE0.e-00, and the Mobile System Profile.... Introduction The adjacent and non-adjacent channel selectivity performance depends on both ACLR (Adjacent Channel Leakage power Ratio) of the interferer transmitter and the ACS (Adjacent Channel Selectivity) of the receiver. The interference experienced in a realistic environment can come from different sources depending on the type of interferers and their out-of-band emission masks, as well as the channel spacing. The standard does not specify the type of interferers, but rather just describes the test as: The adjacent channel selectivity and alternate channel selectivity shall be measured by setting the desired signal s strength db above the rate dependent receiver sensitivity and raising the power level of the interfering signal until the specified error rate is obtained. The power different between the interfering signal and the desired channel is the corresponding adjacent channel selectivity. The interfering signal in the adjacent channel shall be a conforming OFMDA signal, not synchronized with the signal in the channel under test. For non-adjacent channel testing the test method is identical except the interfering channel shall be any channel other than the adjacent channel or the co-channel. ACS is a measure of a receiver s ability to receive a OFDMA signal at its assigned channel frequency in the presence of an adjacent channel signal at a given frequency offset from the centre frequency of the assigned channel. ACS is the ratio of the receive filter attenuation on the assigned channel frequency to the receive filter attenuation on the adjacent channel(s). The Adjacent Channel Interference Power Ratio (ACIR) is the ratio of the total power transmitted from a source (both BS and MS) to the total interference power affecting a victim receiver, resulting from both transmitter and receiver imperfections. When the ACLR of the interference source is much better than receiver ACS performance, the adjacent channel selectivity performance is determined by the ACS performance....

53 Page of Testing requirements The testing requirements include:. The adjacent and non-adjacent channel leakage ratio of the test interfering sources should have negligible impact to the receiver ACS measurement. In particular, the ACLR (adjacent and non-adjacent) requirement should be better than 0dB and 0dB, respectively. ACLR performance can be derived from the interfering source s spectrum mask and the channel spacing (CS). The channel spacing (CS) is determined as the same as channel bandwidth of the desired system, except for systems with a bandwidth of.mhz. For.MHz channel BW, CS is defined as MHz.. Interfering source is an OFDMA conforming unsynchronized signal with a default frame structure defined in Appendix. The averaged power of the interference is a time-triggered measurement only over the duration of the data burst according to the specification defined in the sensitivity test....

59 Page of MS-0.: MS receiver sensitivity The purpose of the test is to verify that the receiver is compliant to the sensitivity requirements as specified in the PICS document and the mobile profile. The requirements are for various MCS levels and the test channel conditions include both AWGN and fading.... Introduction In order to be compliant to the receiver sensitivity requirement, the receiver is required to achieve a Packet Error Rate (PER) equal to or better than a certain target level when the received signal is set at the sensitivity level. The PER, rather than the Bit Error Rate (BER), is calculated over a large number of frames to verify that the performance is better than or equal to the target PER. For AWGN channels, the target PER is converted from the packet size and the standard requirement of BER=e-, assuming independent error event after decoding (Appendix ). For fading channels, the target PER is 0%, which is assumed to be near the target PER of a first HARQ transmission. Two options of test mechanisms can be used for this test:. ACK/NACK mechanism (mandatory for wave-): The packets are allocated in HARQ DL MAP IE with assigned ACK channel for MS UUT to feed back either ACK or NACK for each of the data packets (bursts) transmitted in the previous frame. The ACK/NACK feedback mechanism is the same as used in HARQ operation, even though the Test BS will not re-transmit in the case of receiving a NACK. Each packet transmitted in a frame is a new packet (i.e., AI_SN toggles at each frame). The downlink allocation information for each packet (burst) is conveyed in HARQ DL MAP IE and the receiver feeds back ACK/NACK in the assigned ACK channels within the specified HARQ ACK region.. Ping mechanism (optional for wave-): The Signaling Unit (BS emulator) uses the Ping command to send some payload bits to the MS UUT at an interval of ms (one frame). The MS will send the payload back if it is decoded successfully. The packet size for AWGN, including all headers and CRC, is chosen to be 0 bytes. However for fading test, the packet length is chosen to be, after encoding, a single FEC block with a maximum data size allowed by the CTC subchannel concatenation rule, i.e., 0// bytes depending on the particular MCS level. The actual number of payload bits for the two test mechanism is:. ACK/NACK mechanism: Each data packet consists of a -byte generic MAC header at the beginning and a -byte CRC- at the end, leaving the remaining as payload bits. Random payload bits are used. The CRC is calculated based on MAC header and the payload.. Ping mechanism (optional for wave-): The header size in a Ping message is bytes with bytes of ICMP control message. In addition to the bytes header in each Ping message, there will be a -byte generic MAC header at the beginning and a -byte CRC- at the end. The Ping payload data length can be variable from 0 to bytes. So, for AWGN test case, the ping payload is 0--0=0 bytes and for fading test case, the ping payload will be //0 bytes, corresponding to PDU sizes of 0// 00 WiMAX Forum Doc Number: WiMAX XX xxx xxx v.0.0

60 Page 0 of bytes respectively. Random payload bits are used. The CRC is calculated based on MAC header and the payload. One () packet (burst) is allocated in a data PUSC/FUSC/AMC zone after the first PUSC zone for control message (MAP and DCD). The data zone extends to the end of the DL sub-frame. The allocation starts from slot +mod(n, Nsch) where n is the frame index and Nsch is the number of slots in the frequency domain (e.g., in - point FFT PUSC). The rest of slots in the data zone (before and after the allocated burst) can use random QPSK symbols. Corresponding to those slots, BSE should use a different CID in the MAP meesage. The per-subcarrier transmit power level of the rest of the data zone is kept the same as the per-subcarrier of the data burst so that the signal power measured for the entire data zone is the same as that in the allocation to the MS UUT....

Testing requirements Direct or Indirect Coverage (D/I) The input signal level, averaged only over the data zone, needs to be set at the appropriate levels, which may requires a time-triggered measurement. Moreover, the power level should be the average over data subcarriers only. If this cannot be achieved, which means that the boosted pilots are also included in the power density adjustment, the. db (/) pilot boosting should be taken into account. The input power level should be set as the sensitivity level given in the PICS tables plus an offset computed as 0log0[(N_data+N_pilot*/)/(N_data+N_pilot)] (given in Table ): Table.

Test procedure ACK/NACK test (For ACK/NACK mechanism only): This test should be performed first to verify that the receiver can feed back ACK/NACK as expected, depending on successful/unsuccessful CRC check. The test procedure is: Step. Use HARQ DL MAP IE to allocate one 0-byte QPSK rate-/ packet in each frame Step. Set the signal level at 0dB above sensitivity Step. For a certain percentage (e.g., 0%) of 000 packets (00 frames), the CRC bits are flipped (negated). Test BS should detect NACK corresponding to those packets and detect ACK otherwise. For those packets that the Test BS expects a ACK, only a single () error can be allowed (i.e., a single NACK for 000 packets). Test case : Receiver sensitivity under AWGN Step.

69 Page of Testing requirements This test requires the Signaling Unit (BSE) to accept packets on the Test Control Network and send them on the DL to the MS UUT. The PCT should be able to control the number of HARQ retransmissions (with and without regard to the correctness of the HARQ burst received from the MS UUT), the repetition code of each burst, and the UIUC for all UL allocations (to control the MCS used for each burst). The Signaling Unit (BSE) should also be able to forward packets received from the MS UUT to the PCT for inspection. Moreover, the Signaling Unit (BSE) should be capable of forwarding all management messages received from the MS UUT, for inspection by the PCT. Some control of the Signaling Unit (BSE) s scheduling is required (See details in Section..0.). The Signaling Unit (BSE) shall support category HARQ UL (receive) buffer and support the aggregate capability when receiving HARQ UL bursts sent by the MS UUT. The Signaling Unit (BSE) shall be able to verify that burst retransmissions by the MS UUT are identical to the original transmission of the same burst. (The signaling Unit may use HARQ combining or any other method for this purpose.) The RCTT shall control the Signaling Unit (BSE) s transmit power and the power with which the Signaling Unit (BSE) instructs the MS UUT to transmit. The Signaling Unit (BSE) shall be configured to comply with the appropriate band class for the MS UUT, and will be configured to use a single zone in the UL or DL during this test. The DL/UL ratio should be set according to Table. Unless otherwise indicated in the test procedure, the MAPs sent by the Signaling Unit (BSE) should be sent with the following MCS and repetition factor: QPSK-/, repetition factor =. Also, unless otherwise indicated in the test procedure, the Signaling Unit (BSE) shall not include HARQ feedback (ACKs and NACKs) in the MAPs. The test requires that the PCT have packet generator and analyzer capabilities. If not otherwise mentioned in the test procedure, the packet generator will output packets at a rate of 00 packets per second. These packets will be ICMP-echorequest packets, with random data for payload, sent to the MS UUT through the Signaling Unit (BSE) s DL connection. The MS UUT shall reply to these packets with ICMP-echo-reply sent back to the packet analyzer, through the UL connection to the Signaling Unit (BSE). The packet analyzer shall be able to verify that the data received is identical to the data sent according to the Identifier and Sequence Number fields in the ICMP-echo-request and ICMP-echo-reply messages. Also, an attenuator should be used to control the received power at the MS UUT. The MS UUT shall support an IP stack (over the WiMAX stack) which includes the IP and ICMP protocols. It shall reply with ICMP-echo-reply to all ICMP-echo-request messages. The minimum rate in which the MS UUT is required to reply to ICMPecho-request messages is 00 packets per second. 00 WiMAX Forum Doc Number: WiMAX XX xxx xxx v.0.0

Create and activate an UL service flow, per Item in Table, using a BSinitiated DSA-REQ, and wait for the transaction to succeed. Test Procedure: Step. Configure the Signaling Unit (BSE) so that it schedules a different ACID in each frame, in a round-robin manner (i.e., retransmissions occur only after n frames, where n is the number of UL HARQ channels). Each ACID allocation is limited to the minimum between the buffer size per channel, according to Table 0 and the needed allocation to transmit a single packet per burst. In any case, the number of byte allocated per UL sub-frame shall not exceed Maximum MAC data byte per UL sub-frame, as reported by the MS UUT in the SBC-REQ message or the available capacity of the UL sub-frame. Step. Configure the Signaling Unit (BSE) so that it schedules transmissions per HARQ UL burst (first transmission toggles AI_SN and in the next transmission AI_SN stays the same, regardless of the success of the first transmission). Step. Configure the Signaling Unit (BSE) to forward only the second transmission of each received burst to the MAC layer (even if the first transmission was successful). Step. Packet generator generates the packet number and size as specified in Table. A new packet is generated as soon as the packet analyzer detects that a packet has been successfully received by the BS.

75 Page of 0 0 MS-0b.: MS Receive HARQ The purpose of this test is to verify proper handling of HARQ DL traffic, including: sending ACK/NACK for proper reception of HARQ bursts, conformance with category parameters and channel mapping. The test also verifies the ability of the MS receiver to achieve increased gain from chase combining in loss scenario Introduction According to the Mobile WiMAX System Profile, the only HARQ mode that is mandated and the only one that will be tested is the Chase Combining with CTC mode. For the DL direction, the 0. standard and the WiMAX Mobile PICS mandate the following functional capabilities: Sending ACK on the ACKCH upon correct reception of a HARQ burst and sending NACK upon incorrect reception. Ability to support HARQ ACK Delay for DL burst of frame. Conformance with category parameters (memory size, number of channels and maximum HARQ bursts in a DL sub-frame). Furthermore, the following performance requirements are described in the 0. standard: Performance improvement due to SNR gain by combining previously erroneously decoded burst and retransmitted burst PICS coverage and test purposes The following PICS items are covered by this test.

76 Page of Testing requirements This test requires the Signaling Unit (BSE) to accept packets on the Test Control Network and send them on the DL to the MS UUT. The PCT should be able to control the number of HARQ retransmissions (with and without regard to the ACK/NACK received from the MS UUT), the repetition of each burst, and the DIUC for all DL allocations (to control the MCS used for each burst). The Signaling Unit (BSE) should also be able to forward packets received from the MS UUT to the PCT for inspection. Moreover, the Signaling Unit (BSE) should be capable of counting or forwarding ACKs and NACKs received from the MS UUT, and all management messages received from the MS UUT, for inspection by the PCT. The Signaling Unit (BSE) should be capable of transmitting a HARQ burst with modified CRC (e.g., CRC bar). Also, some control of the Signaling Unit (BSE) s scheduling is required (See details in section..0.). The Signaling Unit (BSE) shall be configured to comply with the appropriate band class for the MS UUT, and will be configured to use a single zone in the UL or DL during this test. The DL/UL ratio should be set according to Table. Unless otherwise indicated in the test procedure, the MAPs sent by the Signaling Unit (BSE) should be sent with the following MCS and repetition factor: QPSK-/, repetition factor =. The test requires that the PCT have packet generator and analyzer capabilities. If not otherwise mentioned in the test procedure, the packet generator will output packets at a rate of 00 packets per second. These packets will be ICMP-echorequest packets (packet sizes are calculated to make the burst sizes according to Table ), with random data for payload, sent to the MS UUT through the Signaling Unit (BSE) s DL connection. The MS UUT shall reply to these packets with ICMPecho-reply sent back to the packet analyzer, through the UL connection to the Signaling Unit (BSE). The packet analyzer shall be able to verify that the data received is identical to the data sent according to the Identifier and Sequence Number fields in the ICMP-echo-request and ICMP-echo-reply messages. A signal generator, capable of generating white Gaussian noise signal that will be combined with the Signaling Unit (BSE) output, to generate AWGN channel, is needed for this test, to test the combining performance. Also, an attenuator should be used to control the received power at the MS UUT, circulators to separate the DL and UL channels and a combiner. The MS UUT shall support an IP stack (over the WiMAX stack) which includes the IP and ICMP protocols. It shall reply with ICMP-echo-reply to all ICMP-echo-request messages. The minimum rate in which the MS UUT is required to reply to ICMPecho-request messages is 00 packets per second. The MS UUT vendor shall indicate what category the MS supports. This declared category will be used to identify parameters to be used in this test. For Category, the vendor will declare whether the aggregation flag for the DL buffer capability is set or cleared. 00 WiMAX Forum Doc Number: WiMAX XX xxx xxx v.0.0

Turn off the MS UUT. Step. Configure the attenuators so that the average powers at the MS antenna input are according to first scenario in Table. Note. The power of each source can be measured at the combiner input and the combiner loss can be compensated, and there is no requirement on the accuracy of such compensation, as long as the ratio between the signals is maintained as in Table. Step. The additional 0dB attenuation should be applied to all three interfering sources so that the UUT can be connected to the serving BS Step. The BSE should periodically broadcast MOB_NBR-ADV, DCD, and UCD message. Step 0. Turn on the MS UUT and wait until the network entry on the serving BS is completed. Step. The additional 0dB attenuation should be removed from all three interfering sources. Step. The BSE shall assign an Unsolicited MOB_SCN-RSP to the MS with Scan_Duration = 0, Report Mode = periodic report, and report period = 0. The BSE may transmit DL traffic to the MS in every frame. Step. MS UUT shall measure the CINR value for the Interfering Source and and use averaging parameter (i.e., alpha=/) according to the received DCD message. Step.

The BSE receiver should also be able to detect a case that the MS failed to transmit MOB_SCN-REP in a certain frame (e.g. by checking the message CRC) and mark the report as invalid. Step. The BSE should record the correctly reported measurement results from the received MOB_SCN-REP until the BSE received 00 MOB_SCN-REP measurement reports. Step.

95 Page of MS-.: MS Transmit Ranging Support The purpose of this test is to verify compliance of MS equipments against transmit ranging support requirements.... Introduction Mobile WiMAX System Profile and IEEE 0. specification requires the MS is able to adjust its transmission according to ranging information that may be sent by the BS. The ranging information are power adjustment, frequency adjustment and timing adjustment. An MS is compliant if: its transmission signal timing is within ±Tb/ duration with respect to the target time as commanded by the Signaling Unit (BSE), and its transmission center frequency is within ±% of the subcarrier spacing compared to the Signaling Unit (BSE) center frequency, and its transmission signal power level is within the specified accuracy for the requested step size Furthermore, the MS shall set its initial timing offset to the amount of internal fixed delay equivalent to co-locating the MS next to the BS. Moreover, (0.e-00 - section...), At the MS, both the transmitted center frequency and the sampling frequency shall be derived from the same reference oscillator. Thereby, the MS uplink transmission shall be locked to the BS, so that its center frequency shall deviate no more than % of the subcarrier spacing, compared to the BS center frequency during the synchronization period, the MS shall acquire frequency synchronization within the specified tolerance before attempting any uplink transmission. During normal operation, the MS shall track the frequency changes and shall defer any transmission if synchronization is lost. Since the accuracy that the MS should have when it applies the frequency corrections sent by the Signaling Unit (BSE) is not defined, this will not be tested and the Signaling Unit (BSE) will not send any frequency correction. The power control mechanisms included in the ranging process are not addressed in this test, but they are part of the specific power control test. There are two types of ranging codes mandated by the Mobile WiMAX System Profile: symbols long (for Initial Ranging and HO ranging) symbol long (for Periodic Ranging and BWR). Ranging requirements are validated in two sub-tests: Subtest A: by verifying the initial phase of the network entry is passed by the MS though the MS was un-ranged initially (by emulation). Subtest B: by verifying further phases during which MS is in Periodic Ranging are successful though MS get unranged (by emulation). This additional phases follow previous one described in Subtest A and hence assumes the MS has succeeded Initial Ranging and entered the Periodic Ranging phase. 00 WiMAX Forum Doc Number: WiMAX XX xxx xxx v.0.0

MS to BS frequency synchronization tolerance... Testing requirements P P P For this test, the MS shall implement all the features required for achieving successfully initial ranging phase as well as the features for periodic ranging. The MS is connected to the Signaling Unit (BSE) through an attenuator on the bidirectional path. This assumes the Signaling Unit (BSE) has the needed characteristics specifically for measuring the arrival time, the frequency and the power level of the received signals from the MS. The Signaling Unit (BSE) is set such as to have a carrier frequency reference clock that is deviated of - ppm or + ppm compared to the value corresponding to the nominal frequency. Moreover, the timing estimations reported by the Signaling Unit (BSE) shall be expressed as timing difference at the BS antenna port between the first sample of the received symbol (including CP) versus the timing reference. In other words, the timing estimation is zero when first sample of the symbol (including CP) transmitted by the MS is aligned with the time reference at the BS antenna port. The Signaling Unit (BSE) will emulate two situations: near and far MS. For this reason, the DL power level at the MS antenna port (A MS ) will be set to different target values by changing the transmit power level at the Signaling Unit (BSE) and the attenuator value. The two will be modified in such a way that the received signal at the Signaling Unit (BSE) antenna port is within the range of the Signaling Unit (BSE) receiver. The Signaling Unit (BSE) is set such as to have a target arrival time for the uplink data (initial or ranging codes for this test) received from the BS for emulating and modifying the RTD. Four values are considered in this test (RTD_0 = 0 µs, RTD_ = µs, RTD_ = µs, RTD_ = 0 D D D 00 WiMAX Forum Doc Number: WiMAX XX xxx xxx v.0.0

Schedule IR opportunities Demodulate CDMA ranging code and record the timing errors.

The burst allocation in the second UL PUSC zone shall start from the first slot in the zone and occupies all the slots in the zone. This burst uses MCS of -QAM ¾. Test Procedure: Step. Vendor will specify the Power Class (or classes) and the maximum Transmit power of the MS UUT. Step. The Test BSE shall grant the MS UUT an uplink bandwidth according to the UL message defined in the initial condition. Step. The Test BSE sends a ping command every frame with appropriate payload size that will fill all the allocated slots in the second UL PUSC zone defined in the initial condition. Step. The attenuator is adjusted such that the signal level at A BSE is maintained at a level which is within the operating range of the Test BSE, for all MS Transmit power levels. Step. The Test BSE will request the MS UUT to decrease its output power in steps of db up to the moment when the MS power cannot be reduced any further. Step. At each step the power transmitted by the MS, measured in dbm, is recorded. Step. The maximum power is P 0, after the first message the power is P, after the second one it is P, and so on until the last measurement being P N. Step. For a compliant unit, P 0 -- P N shall be at least db,as required by Test MS - Power Level Dynamic Range. Step.

If the relative accuracy is within the range of the required relative accuracy from Table 0, the unit is compliant and meets the requirements for MS- Power level Control Accuracy. Step. Two exceptions at least 0 db apart are allowed over the sequence of db steps across the db range, where in these two cases an accuracy of up to +/- db is allowed.

Then we verify the power corrections issued by the test-bs are properly applied (Step ). Note that in Step.Step we assume the MS should estimate its maximum transmit power based on RSSI measurements with accuracy better than +/-db, and apply this power in the Tx with an accuracy of +/-db, so that the global accuracy should be +/-db. In this test, allocation for RNG-REQ through CDMA_Alloc_IE is PUSC on sub-channels. During this test, the MS-UUT transmit power is supposed to vary as detailed in Table (presented at the end of the section). Step. Set Test BS output power to 0dBm. Set BS_EIRP to 0dBm in the DCD message. Step. Adapt the attenuation in the DL so that the received signal level at A MS is -0 dbm. Use the same attenuation in the UL. Step. Set BS_EIRxPIRMAX to -0dBm in the DCD. Since the attenuation in the path is 0dB, we have PTX_IR_MAX=0dBm at the MS UUT. 00 WiMAX Forum Doc Number: WiMAX XX xxx xxx v.0.0

Let P be the power measured on first IR code received after the 0s period expired. The Test BS calculates the needed correction m=ptarget-p and sends RNG-RSP with continue status and adjustments. Ptarget is the target received power, set to -0dBm. Step. The Test BS demodulates IR CDMA code in the periodic ranging region and records the power statistic P achieved.

In this test, all UL allocation is PUSC on sub-channels QAM /, except in Step. Moreover, the test-bs shall ensure that data allocation to the MS-UUT does not overlap in time with other allocations. During this test, the MS-UUT transmit power is supposed to vary as detailed in Table. Step. A connection is setup between the MS UUT to the Test BS. Step. The Test BS requests the MS UUT to report its maximum transmit power Pmax (in dbm) and current transmitted power Pcurrent (in dbm per sub-carrier). The Test BS sends a power correction to the MS UUT to get it at below saturation. The correction is Pmax-Pcurrent-0log(). Step. The BS measures the received power on the received burst RxP 0. Step.

It is verified that the received power RxP is in the range RxP 0 +/- 0. db. Step. The Test BS requests the MS UUT to decrease its output power in steps of 0 db, times. At each step the power transmitted by the MS UUT, measured in dbm, is recorded. Step. The initial power is RxP 0, after the first message the power is RxP, after the second one is RxP, and RxP after the third one. One data Burst per Frame is to be used with TBD frames to obtain an accurate reading in the Test BS. It is verified that at each step (RxP N -RxP N- = 0dB +/- db). Step. The Test BS allocates burst on sub-channels, measure P. The MS UUT is compliant if (P -P ) equal db +/-0,dB. One data Burst per Frame is to be used with TBD frames to obtain an accurate reading in the Test BS. Sub-Test OLPC In OLPC passive mode, the Tx power is defined by equation a (page of [0.e-00]): In this test, we test that each term is applied properly: 0.log0(R) (Step ), C/N (Step ), NI (Step ), Offset_BSperSS (Step and Step ), L (Step and Step 0). We also test that the term OffsetSS_perSS is properly initialized (according to TWG comment #, IEEE #), but afterward it is kept constant (passive mode, active mode is out of scope of the test). Moreover, we ensure the transition between CLPC and OLPC is OK (Step ), and that the MS- UUT keeps its PSD constant when the test-bs lets the number of sub-channels vary (Step ). L shall be calculated based on the total power on the used sub carriers of the frame preamble in the DL on one side. RSSI precision shall be better than +/-db on the other side. Here we assume that precision on L is as required on the RSSI. In this test, all UL allocation are PUSC on sub-channels, except in Step. The Test BS and the MS UUT keep the OLPC mode from Step to Step. Moreover, the test-bs shall ensure that data allocation to the MS-UUT does not overlap in time with other allocations. During this test, the MS-UUT transmit power is supposed to vary as detailed in Table. Step. The power control mode of the MS is CLPC mode. Set BS_EIRP to 0dBm in the DCD message. The Test BS advertises NI = -00 dbm. Step.

128 Page of MS-0.: MS transmit/receive switching gap The purpose of this test is to verify MS compliance to the min Transmit/receive Transition Gap (SSTTG) and Receive/transmit Transition Gap (SSRTG) requirements Introduction This test shall make certain that the MS can perform switching between receive and transmit states quick enough to meet the PICS requirements. In order to perform these measurements the start and end of the two switching events must be defined. For testing purposes the SSRTG is defined as the time between end of the last sample of the last OFDM-symbol of the DL and the start of the first sample of the first OFDM-symbol of the UL frame, see Figure. For testing purposes the SSTTG is defined as the time between end of the last sample of the last OFDM-symbol of the UL and the start of the first sample of the preamble of the following DL frame. To be certain that the UUT can perform the switching it is not sufficient to measure that an RF-signal is present at these positions of the MAC-frame, the UUT also need to have some level of performance at these points. In order to ensure this both downlink and uplink traffic must be tested. When testing SSRTG performance, the Signaling Unit (BSE) shall command the MS to send and receive data at fixed positions in the MAC-frame, the pattern to be repeated continuously for the duration of test. PER shall be measured on a PDU positioned as late as possible in the DL frame and Relative Constellation Error shall be measured on the first symbol of the UL frame averaged over 00 bursts. The SSTTG shall be tested with the same approach. The Signaling Unit (BSE) shall command the MS to send and receive data at fixed positions in the MAC-frame, the pattern to be repeated continuously for the duration of test. Relative Constellation Error shall be measured on the last symbol of the UL frame averaged over 00 bursts and PER shall be measured on a PDU positioned as early as possible in the DL frame. 00 WiMAX Forum Doc Number: WiMAX XX xxx xxx v.0.0

149 Page of BS-0.: BS receiver adjacent and non-adjacent channel selectivity The purpose of this test is to verify that the BS receiver can meet the Adjacent and Nonadjacent Channel Selectivity defined in IEEE0.-00, IEEE0.e-00, and the Mobile System Profile Introduction Reference [] (IEEE P0.e-00) specifies that first adjacent channel selectivity at BER=0 for db degradation C/I and second adjacent channel selectivity at BER=0 for db degradation C/I, both for -QAM-/ case. This is verified by measuring the packet error lower than the defined limits. The adjacent and non-adjacent channel selectivity performance depends on both ACLR (Adjacent Channel Leakage power Ratio) of the interferer transmitter and the ACS (Adjacent Channel Selectivity) of the receiver. The interference experienced in a realistic environment can come from different sources depending on the type of interferers and their out-of-band emission masks, as well as the channel spacing. ACS is a measure of a receiver s ability to receive an OFDMA signal at its assigned channel frequency in the presence of an adjacent channel signal at a given frequency offset from the centre frequency of the assigned channel. ACS is the ratio of the receive filter attenuation on the assigned channel frequency to the receive filter attenuation on the adjacent channel(s). The Adjacent Channel Interference Power Ratio (ACIR) is the ratio of the total power transmitted from a source (both BS and MS) to the total interference power affecting a receiver, resulting from both transmitter and receiver imperfections. When the ACLR of the interference source is much better than receiver ACS performance, the adjacent channel selectivity performance is determined by the ACS performance PICS coverage and test purposes The following PICS items are covered by this test.

150 Page 0 of The adjacent and non-adjacent channel leakage ratio of the test interfering sources should have negligible impact to the receiver ACS measurement. In particular, the ACLR (adjacent and non-adjacent) requirement should be better than 0dB and 0dB, respectively. ACLR performance can be derived from the interfering source s spectrum mask and the channel spacing (CS). The channel spacing (CS) is determined as the same as channel bandwidth of the desired system, except for systems with a bandwidth of.mhz. For.MHz channel BW, CS is defined as MHz. Interfering source(signal) is an OFDMA signal with the same channel bandwidth, unsynchronized with the desired signal, and be in a continuous transmission mode with a default frame structure defined in Appendix.

156 Page of BS-0.: BS receiver sensitivity The purpose of this test is to verify that the BS receiver can meet the minimum input level sensitivity requirement defined in IEEE0.e-00 and the Mobile System Profile for both Convolutional Coding and Convolutional Turbo Coding modes Introduction In order to be compliant to the minimum receiver sensitivity requirement, the receiver is required to achieve a Packet Error Rate (PER) equal to or better than a certain target level when the received signal is set at the maximum sensitivity level. In the test, the BS is required to keep count of correct and false MAC-CRCs all the data packets (bursts) received. The PER, rather than the Bit Error Rate (BER), is calculated over a large number of frames to verify that the performance is better than or equal to the target PER. For AWGN channels, the target PER is converted from the packet size and the standard requirement of BER=e-, assuming independent error event after decoding (Appendix ). For fading channels, the target PER is 0%, which is assumed to be near the target PER of a first HARQ transmission. The packet length is chosen to be, after encoding, a single FEC block with a maximum data size allowed by the CTC sub-channel concatenation rule, i.e., 0/ bytes depending on the particular MCS level. Each data packet consists of a -byte generic MAC header at the beginning and a -byte CRC- at the end, leaving the remaining as payload bits. Random payload bits are used. The CRC is calculated based on MAC header and the payload. IEEE0.e-00 specifies that the BER measured after the FEC shall be less than 0 at the power levels given by Fs N Used Rss = + SNRRx 0 log 0 ( R) + 0 log0 + ImpLoss + NF NFFT Where SNR Rx is the receiver SNR for different levels of coding rate and modulation, R is the repetition factor, as described in Section.., F S is the sampling frequency in MHz as defined in Section..., ImpLoss is the implementation loss, which includes non-ideal receiver effects such as channel estimation errors, tracking errors, quantization errors, and phase noise. The assumed value is db. N F is the receiver noise figure, referenced to the antenna port. The assumed value is db. The specification further defines that the minimum input levels are measured as follows: Using the defined standardized message packet formats. Using an AWGN channel. The test verifies that the BS under test will conform to the minimum performance requirement set forth in the standard, i.e., under maximum implementation loss of db and maximal noise figure of db, i.e., 00 WiMAX Forum Doc Number: WiMAX XX xxx xxx v.0.0

According to the Mobile System Profile, CC is mandatory only for FCH, and CTC is used in all other transmissions. Therefore, the receiver SNR table defined in the Mobile System Profile will be used for CTC reception testing Note: the values there are for 0// bytes only.

The BS UUT is set to the maximum output power of the BS minus 0 db and the power at the input of the VSA is adjusted to ensure that the input level is appropriate for the specifications of the VSA. Test Procedure Step.

184 Page of BS-.: BS Transmitter Relative Constellation Error The purpose of this test is to verify BS conformance to transmitter relative constellation error fidelity requirements as required by the IEEE 0.e-00 standard and the TWG profile requirements Introduction The Standard [] dictates that all measurements will be referenced to the RF antenna connector (i.e., at PA output without antenna). To ensure that Receiver s SNR will be degraded by no more than 0. db due to transmitter s SNR, the relative constellation RMS error, averaged over subcarriers, OFDMA frames and packets, shall not exceed the values listed in Table. Since the DL sub-frame may contain several different zones, the pilot level may shift when transitioning from zone to zone. The test may be performed on any permutation zone. In order to verify the receiver s SNR, the EVM test contains actually a receiver in which after PA output the signal is demodulated and the SNR is measured according to the following steps:. The BS transmits the required signal.. The preamble is located, i.e. initial coarse frame synchronization is performed.. From the preamble timing and frequency estimation is performed.. The timing offset is compensated as estimated.. The received signal shall be de-rotated according to the estimated frequency offset.. The VSA should use all available transmitted pilots, preamble subcarriers and data subcarriers for channel estimation purposes.. The VSA should use all available transmitted pilots, preamble subcarriers and data subcarriers for channel estimation purposes.. Each sub-carrier value is divided by the corresponding channel estimate value.. For each sub-carrier value (i.e, data + pilot sub-carriers) we should find the closest constellation point and make a decision subcarriers. 0.

Item, Table A Test Requirements T Partial or Total Coverage (P/T) D Direct or Indirect Coverage (D/I) For the purpose of measuring the BS relative constellation error (known also as EVM) a packet generator (signal generator) is used to generate the required data traffic bytes/bits. The BS under test (BS-UUT) will frame the data, encode it and modulate it according to 0.e requirements. The VSA will demodulate the signal and will calculate the required relative constellation error.. In addition the average power will be calculated. The test will be repeated at two output power levels - maximum output power and minimum power which should be 0 db less than the maximum power. The test will be repeated at low and high frequencies in the applicable RF profile. For MHz channels FFT will be employed. For all other channel bandwidths (,. and 0 MHz) 0 FFT will be employed.

Test Setup for BS Transmitter Relative Constellation Error (BS-.) In this setup, the power at the VSA input shall be adjusted in order to assure correct operation of the VSA Test Procedure In the proposed test BS is connected to VSA, which measures the transmitter constellation error. In each transmission the BS sends one DL sub-frame on the maximum allowed DL sub-frame size allowed by the profile, and the VSA decodes it and computes the metric defined in Equation. Each modulation is tested at the lowest and highest channel frequencies supported by the BS in the applicable RF profile. The reported metric will be the RMS average of the per frame measured metric where the averaging period is L should be 00 frames (sec). The metric proposed at [](Eq. of IEEE 0.e-00) shall be computed based on preamble, data and pilot subcarriers. The output power as measured by the VSA will be recorded and stored. The Relative constellation error will be repeatedly measured for both PUSC, FUSC and BAMC (applicable to wave testing only). In PUSC permutation the test will be done at full loading scenario only. The VSA demodulates each frame according to the steps described in Section 0...and computes the error vector per frame and after that by RMS averaging the final error vector is computed. The VSA performs channel estimation on preamble, pilot and data subcarriers to minimize channel estimation errors.

188 Page of BS-.: BS synchronization The purpose of this test is to verify the BS under test meets the frequency synchronization requirements as defined in Section... and 0.e-00 Section... These conditions include: a) BS synchronization in time, slot, frequency, TX reference timing accuracy and frequency accuracy requirements. b) BS clock frequency error is +/- ppm in non-synchronized work and +/-% carrier spacing in synchronized work as required by IEEE0.-00 and IEEE0.e-00 and the Mobile System Profile. c) The transmitted center frequency, receive center frequency and the symbol clock frequency are derived from the same reference oscillator Introduction In order to reduce interference between different BSs operating in the same geographic area and in order to allow fast and soft handover of a MS between these BSs time synchronization of the OFDMA frame and frequency synchronization of the RF signals of the involved BSs is required. For normal synchronized mode - which is required to minimize interference between different BSs - Mobile WiMAX System Profile and IEEE 0. specifications require that the start of the preamble symbol, excluding the CP duration, of the downlink radio frame shall be time aligned with pps timing pulse when measured at the antenna port. Mobile WiMAX System Profile requires an accuracy of ± us for alignment with the pps signal. The allowed BS clock and RF center frequency error in normal synchronized mode is ± ppm. For time and frequency synchronized operation - which is required for fast and soft handovers - Mobile WiMAX System Profile and IEEE 0. specifications require that the downlink frames transmitted by a serving BS and the neighbor BS shall be synchronized to a level of at least / cyclic prefix length. BS reference clocks shall be synchronized to a level that yield RF center frequency offsets of no more than % of the OFDMA carrier spacing of the neighbor BS. The synchronizing reference shall be a pps timing pulse and for example a 0 MHz frequency reference (although a different frequency reference may be used). These signals are typically provided by a GPS receiver. NOTE: As the test is performed with one BS against the reference signal and not against a second BS, an additional margin (as described in the system profile document) is taken into account. CP=/ corresponds to. us in and 0 MHz channels. To reflect this and to comply with the system profile document the timing accuracy of the transmitted signal (as measured at antenna port) should be us within the synchronizing external pps signal. Also, RF center frequency offset of no more than % of the OFDMA subcarrier spacing of the neighbor BS. As the requirements for time and frequency synchronized operation are more stringent these will be used for the requirements of this test PICS coverage and test purposes The following PICS items are covered by this test: 00 WiMAX Forum Doc Number: WiMAX XX xxx xxx v.0.0

A vector signal analyzer capable of processing 0.e DL frames and detecting the start of the downlink frames to measure the RF center frequency deviation of the DL signal is required. Also, a high precision pps timing pulse and high accuracy frequency reference are required for connection to the vector signal analyzer. (Typically, these signals are provided by a reference GPS receiver.) Because it is not possible to test if the transmitted center frequency, receive center frequency and the sampling frequency are derived from the same reference oscillator, the UUT vendor shall provide a written declaration guaranteeing that this requirement is met. Further, the UUT vendor shall declare how his UUT achieves synchronization (i.e. internal GPS receiver, external GPS receiver.) 0... Test setup The test setup below is considered as one possible solution for the synchronization measurement. The BS UUT and the VSA should be connected to highly accurate clock sources as demonstrated in Figure when testing frequency requirement under synchronized conditions. The clock source for the UUT - the UUT GPS receiver - can be external equipment or can be integrated in the UUT. In the latter case, a GPS antenna is connected to the UUT to feed the internal GPS receiver. At the BS, the top transmit frequency will be tested In case of more than one transmit antenna connector the test shall be performed on one randomly selected transmit antenna connector. For a case of transmit delay diversity the measurement will be done on the output port of the non-delayed antenna element.

In order to perform these measurements the start and end of the two switching events must be defined. For testing purposes the TTG is defined as the time between end of the last sample of the last OFDM-symbol of the DL and the start of the first sample of the first OFDMsymbol of the UL frame, see Figure. For testing purposes the RTG is defined as the time between end of the last sample of the last OFDM-symbol of the UL and the start of the first sample of the preamble of the following DL frame. To be certain that the UUT can perform the switching it is not sufficient to measure that an RF-signal is present at these positions of the MAC-frame, the UUT also need to have some level of performance at these points. In order to ensure this both downlink and uplink traffic must be tested. When testing RTG performance, the BS shall set up the test-ms to send and receive data at fixed positions in the MAC-frame, the pattern to be repeated continuously for the duration of test. PER shall be measured on a burst prolonged as long as to reach the end of UL frame and Relative Constellation Error shall be measured on the first symbol of the DL frame averaged over 00 bursts. The TTG shall be tested with the same approach. The BS shall command the test- MS to send and receive data at fixed positions in the MAC-frame, the pattern to be repeated continuously for the duration of test. Relative Constellation Error shall be measured on the last symbol of the DL frame averaged over 00 bursts and error rate shall be measured on a first symbols in the UL frame. Note that the first symbols in the UL frame are allocated for ranging channels, CQICHs and ACKCHs for default frame structure in Appendix. 00 WiMAX Forum Doc Number: WiMAX XX xxx xxx v.0.0

Test Packets Test messages for measuring Receiver Sensitivity shall be based on a continuous stream of MAC PDUs, each with a payload consisting of a R times repeated sequences S modulation. A different sequence is defined for each modulation as follows: SQPSK = {0xE, 0xB, 0xE, 0xB} for QPSK; SQAM = {0xA, 0x0, 0xB, 0x, 0xEC, 0x, 0xFD, 0x} for QAM; SQAM = {0xB, 0x, 0x, 0xB, 0x, 0x0, 0x, 0x, 0x, 0x, 0x0, 0x00, 0xBA, 0xA, 0xA, 0xA, 0x, 0x, 0xD, 0x, 0x, 0xD, 0x0, 0x0, 0xDB, 0x, 0x, 0xF, 0x, 0x, 0xF, 0x, 0x, 0xBE, 0xB, 0xCB, 0xE, 0x, 0xC, 0xDF, 0x, 0xD, 0xFB, 0xA, 0xA, 0xFF, 0xB, 0xDB} for QAM.

217 Page of AMC CTC-QPSK-/ -. AMC CTC-QAM-/ -. AMC CTC-QAM-/ -. Bit Error Rate (BER) versus Packet Error Rate (PER) The relationship between the BER and PER is valid for an ideal communication system that transmits data over binary symmetric channel with uncorrelated noise. This relationship is not valid for correlated noise channels and is dependent on the specific receiver implementation. The length of the packet in bits is n and the bit error probability for the channel is p b. Any packet that has one bit or more in error is discarded and the probability p of getting a packet in error is given by: p = ( ) n Equation n p b p n is the packet error rate (PER) and p b is the bit error rate (BER). If we transmit N packets the probability to get k packets in error is binomially distributed. A real communications system is considered equivalent to the ideal system if they have the same PER. The equivalency means that the real system has the same packet throughput as the reference ideal system having the known BER=0 -. The PER is determined exclusively by the BER and the number of bits in the packet s data payload and is not dependent by how the data is encoded or what happens during the transmit-receive process. Therefore the relationship between PER and BER is given by: n = ( BER Equation PER ) The PER is defined as the limit of the ratio between the number of the packets in error (Npe) to the number of the packets transmitted (Npt) when Npt goes to infinity. Therefore PER cannot be measured in a finite time measurement. Instead we define experiments that, once validated, will give a defined level of confidence that the PER is less than the requirement. An experiment is defined by the level of confidence α, the value of the PER, the total number of N packets transmitted and the maximum number M of packets that can be in error for the experiment to be considered valid. M is determined from N, PER and α such that the probability for a system that has a PER higher than the nominal one to pass the test is less than -α. The number M is the highest one that verifies the inequality: k= M N k p n = n k k N k ( p ) α Equation 00 WiMAX Forum Doc Number: WiMAX XX xxx xxx v.0.0

218 Page of Qualitative tests and functional tests Qualitative tests, like receiver sensitivity or adjacent channel rejection, measure the PER in order to assess the quality of the UUT. The base standard requires some minimum value for the performance of the UUT and the test ensures that the capability of the UUT meets that requirement. For qualitative tests the number N of packets to be transmitted is determined such that M is high enough for the experiment to be significant and N is not excessively high in order to limit the test duration. For an arbitrarily chosen M value between 00-00, and for the payload sizes of the test packets, Table summarizes the parameters for 0% level of confidence: Message Default_Packet w bytes overhead Default_Packet w bytes overhead Table. Parameters for Qualitative tests and Acceptance Limit Packet Threshold Number of Maximum number Length (bits) PER packets sent N of error packets M (+) x 0.% 0,000 (+) x 0.% 0,000 Functional tests make sure a function is implemented in the UUT and that the UUT responds to the control signals commanding this feature. In this case the quality of the UUT is not measured, but it is simply required that the receiver receives data correctly when a high quality signal is transmitted. Functional tests make sure a function is implemented in the UUT and that the UUT responds to the control signals commanding this feature. In this case the quality of the UUT is not measured, but it is simply required that the receiver receives data correctly when a high quality signal is transmitted. Therefore in many tests the S/N ratio is adjusted to be approximately 0 db above the actual threshold to ensure the quality of the signal. For an ideal receiver the BER would be very low with a 0 db margin. In reality we cannot demand more than what is required in the standard which is BER=0-. So receives data correctly means BER<= 0- after FEC. The receiver input level for functional tests is 0 db higher than Sensitivity numbers of Table - unless specified otherwise in test procedure. For functional tests, in order to limit the test duration, we chose arbitrarily the number of packets to be sent one fifth of the number of packets sent in qualitative tests.
