A transport channel is defined by how and with what characteristics data is transferred over the air interface. A general classification of transport channels is into two groups: - Dedicated Channels, using inherent addressing of UE - Common Channels, using explicit addressing of UE if addressing is needed General concepts about transport channels are described in [12]..1.1 Dedicated transport channels There exists two types of dedicated transport channel, the Dedicated Channel (DCH) and the Enhanced Dedicated Channel (E-DCH)..1.1.1 DCH Dedicated Channel The Dedicated Channel (DCH) is an up- or downlink transport channel that is used to carry user or control information between the UTRAN and a UE..1.1.2 E-DCH Enhanced Dedicated Channel The Enhanced Dedicated Channel (E-DCH) is an uplink transport channel..1.2 Common transport channels There are seven types of common transport channels for 3.Mcps and 7.6Mcps TDD: BCH, FACH, PCH, RACH, USCH, DSCH, HS-DSCH. There are eight types of common transport channels for 1.2Mcps TDD: BCH, FACH, PCH, RACH, USCH, DSCH, HS-DSCH, E-DCH.
3GPP TS 25.221 version.5.0 Release TS 125 221 V.5.0 (2009-06).1.2.1 BCH - Broadcast Channel The Broadcast Channel (BCH) is a downlink transport channel that is used to broadcast system- and cell-specific information..1.2.2 FACH Forward Access Channel The Forward Access Channel (FACH) is a downlink transport channel that is used to carry control information to a mobile station when the system knows the location cell of the mobile station. The FACH may also carry short user packets..1.2.3 PCH Paging Channel The Paging Channel (PCH) is a downlink transport channel that is used to carry control information to a mobile station when the system does not know the location cell of the mobile station..1.2. RACH Random Access Channel The Random Access Channel (RACH) is an up link transport channel that is used to carry control information from mobile station. The RACH may also carry short user packets..1.2.5 USCH Uplink Shared Channel The uplink shared channel (USCH) is an uplink transport channel shared by several UEs carrying dedicated control or traffic data..1.2.6 DSCH Downlink Shared Channel The downlink shared channel (DSCH) is a downlink transport channel shared by several UEs carrying dedicated control or traffic data..1.2.7 HS-DSCH High Speed Downlink Shared Channel The High Speed Downlink Shared Channel (HS-DSCH) is a downlink transport channel shared by several UEs. The HS-DSCH is associated with one or several Shared Control Channels (HS-SCCH). The HS-DSCH is transmitted over the entire cell or over only part of the cell using e.g. beam-forming antennas. For 1.2Mcps TDD, in a multi-frequency HS-DSCH cell, the HS-DSCH may be transmitted to a UE on one or more carriers in CELL_DCH state and on only one carrier in CELL_FACH, CELL_PCH and URA_PCH state in a TTI. The term multi-carrier HS-DSCH reception refers to the HS-DSCH reception on multiple carriers in a TTI for a UE..1.2. E-DCH Enhanced Dedicated Channel The Enhanced Dedicated Channel (E-DCH) is an uplink transport channel in CELL_FACH and IDLE mode for 1.2Mcps TDD only..2 Indicators Indicators are means of fast low-level signalling entities which are transmitted without using information blocks sent over transport channels. The meaning of indicators is implicit to the receiver. The indicator(s) defined in the current version of the specifications are: Paging Indicator (PI) and MBMS Notification Indicator (NI).
3GPP TS 25.221 version.5.0 Release 17 TS 125 221 V.5.0 (2009-06) 5 Physical channels for the 3. Mcps option Sub-clauses 5.1 to 5.7 do not apply to 3. Mcps MBSFN IMB. Sub-clause 5. describes physical channels for 3. Mcps MBSFN IMB. All physical channels take three-layer structure with respect to timeslots, radio frames and system frame numbering (SFN), see [1]. Depending on the resource allocation, the configuration of radio frames or timeslots becomes different. All physical channels need a guard period in every timeslot. The time slots are used in the sense of a TDMA component to separate different user signals in the time domain. The physical channel signal format is presented in figure 1. A physical channel in TDD is a burst, which is transmitted in a particular timeslot within allocated Radio Frames. The allocation can be continuous, i.e. the time slot in every frame is allocated to the physical channel or discontinuous, i.e. the time slot in a subset of all frames is allocated only. A burst is the combination of two data parts, a midamble part and a guard period. The duration of a burst is one time slot. Several bursts can be transmitted at the same time from one transmitter. In this case, the data parts must use different OVSF channelisation codes, but the same scrambling code. The midamble parts are either identicaly or differently shifted versions of a cell-specific basic midamble code, see section 5.2.3. Note when in MBSFN operation, a midamble is not necessarily cell-specific. Radio Frame (10ms) frame #i frame #i+1 Time Slot (2560*T c ) timeslot #0 timeslot #1 timeslot #2 timeslot #13 timeslot #1 Figure 1: Physical channel signal format The data part of the burst is spread with a combination of channelisation code and scrambling code. The channelisation code is a OVSF code, that can have a spreading factor of 1, 2,,, or. The data rate of the physical channel is depending on the used spreading factor of the used OVSF code. The midamble part of the burst can contain two different types of midambles: a short one of length 256 chips, or a long one of 512 chips. The data rate of the physical channel is depending on the used midamble length. Additionally, when in MBSFN operation a midamble of length 320 chips is used. So a physical channel is defined by frequency, timeslot, channelisation code, burst type and Radio Frame allocation. The scrambling code and the basic midamble code are broadcast and may be constant within a cell. When a physical channel is established, a start frame is given. The physical channels can either be of infinite duration, or a duration for the allocation can be defined. 5.1 Frame structure The TDMA frame has a duration of 10 ms and is subdivided into 15 time slots (TS) of 2560*T c duration each. A time slot corresponds to 2560 chips. The physical content of the time slots are the bursts of corresponding length as described in subclause 5.2.2. Each 10 ms frame consists of 15 time slots, each allocated to either the uplink or the downlink (figure 2). With such a flexibility, the TDD mode can be adapted to different environments and deployment scenarios. In any configuration at least one time slot has to be allocated for the downlink and at least one time slot has to be allocated for the uplink with the exception of no uplink timeslots when the entire carrier is dedicted to MBSFN

3GPP TS 25.221 version.5.0 Release 19 TS 125 221 V.5.0 (2009-06) 5.2.1 Spreading Spreading is applied to the data part of the physical channels and consists of two operations. The first is the channelisation operation, which transforms every data symbol into a number of chips, thus increasing the bandwidth of the signal. The number of chips per data symbol is called the Spreading Factor (SF). The second operation is the scrambling operation, where a scrambling code is applied to the spread signal. Details on channelisation and scrambling operation can be found in []. 5.2.1.1 Spreading for Downlink Physical Channels Downlink physical channels shall use SF =. Multiple parallel physical channels can be used to support higher data rates. These parallel physical channels shall be transmitted using different channelisation codes, see []. These codes with SF = are generated as described in []. Operation with a single code with spreading factor 1 is possible for the downlink physical channels. 5.2.1.2 Spreading for Uplink Physical Channels The range of spreading factor that may be used for uplink physical channels shall range from down to 1. For each physical channel an individual minimum spreading factor SF min is transmitted by means of the higher layers. There are two options that are indicated by UTRAN: 1. The UE shall use the spreading factor SF min, independent of the current TFC. 2. The UE shall autonomously increase the spreading factor depending on the current TFC. If the UE autonomously changes the SF, it shall always vary the channelisation code along the branch with the higher code numbering of the allowed OVSF sub tree, as depicted in []. In the event that code hopping is configured by higher layers, the allowed OVSF sub-tree is that subtended by the effective allocated OVSF code after the hop sequence has been applied to the allocated OVSF code (see [9]). For multicode transmission a UE shall use a maximum of two physical channels per timeslot simultaneously. These two parallel physical channels shall be transmitted using different channelisation codes, see []. 5.2.2 Burst Types Four types of bursts for dedicated physical channels are defined. All of them consist of two data symbol fields, a midamble and a guard period, the lengths of which are different for the individual burst types. Thus, the number of data symbols in a burst depends on the SF and the burst type, as depicted in table 1. Table 1: Number of data symbols (N) for burst types 1, 2, 3 and Spreading factor (SF) Burst Type 1 Burst Type 2 Burst Type 3 Burst Type 1 1952 220 156 2112 2 976 110 92 N/A 552 6 N/A 2 276 232 N/A 122 13 1 132 The support of burst types 1, 2 and 3 is mandatory for UEs supporting transmit and receive functions. UEs supporting transmit and receive functions and also MBSFN operation must additionally support burst type. UEs with receive only capability need only support burst type. The four different bursts defined here are well suited for different applications, as described in the following sections. 5.2.2.1 Burst Type 1 The burst type 1 can be used for uplink and downlink. Due to its longer midamble field this burst type supports the construction of a larger number of training sequences, see 5.2.3. The maximum number of training sequences depend on the cell configuration, see annex A. For the burst type 1 this number may be,, or.
3GPP TS 25.221 version.5.0 Release 20 TS 125 221 V.5.0 (2009-06) The data fields of the burst type 1 are 976 chips long. The corresponding number of symbols depends on the spreading factor, as indicated in table 1 above. The midamble of burst type 1 has a length of 512 chips. The guard period for the burst type 1 is 96 chip periods long. The burst type 1 is shown in Figure. The contents of the burst fields are described in table 2.

It offers a longer data field than burst type 1 on the cost of a shorter midamble. Due to the shorter midamble field the burst type 2 supports a maximum number of training sequences of 3 or 6 only, depending on the cell configuration, see annex A. The data fields of the burst type 2 are 110 chips long. The corresponding number of symbols depends on the spreading factor, as indicated in table 1 above. The guard period for the burst type 2 is 96 chip periods long.the burst type 2 is shown in Figure 5. The contents of the burst fields are described in table 3.

Due to the longer guard period it is suitable for initial access or access to a new cell after handover. It offers the same number of training sequences as burst type 1. The data fields of the burst type 3 have a length of 976 chips and 0 chips, respectively. The corresponding number of symbols depends on the spreading factor, as indicated in table 1 above. The midamble of burst type 3 has a length of 512 chips. The guard period for the burst type 3 is 192 chip periods long. The burst type 3 is shown in Figure 6. The contents of the burst fields are described in table.

GP denotes the guard period and CP the chip periods 5.2.2. Transmission of TFCI All burst types 1, 2, 3 and provide the possibility for transmission of TFCI. The transmission of TFCI is negotiated at call setup and can be re-negotiated during the call. For each CCTrCH it is indicated by higher layer signalling, which TFCI format is applied, except for the MBSFN FACH where the (,5) biorthogonal code is always used for TFCI when TFCI is applied. Additionally for each allocated timeslot it is signalled individually whether that timeslot carries the TFCI or not. The TFCI is always present in the first timeslot in a radio frame for each CCTrCH. If a time slot contains the TFCI, then it is always transmitted using the physical channel with the lowest physical channel sequence number (p) in that timeslot. Physical channel sequence numbering is determined by the rate matching function and is described in [7]. The transmission of TFCI is done in the data parts of the respective physical channel. In DL the TFCI code word bits and data bits are subject to the same spreading procedure as depicted in []. In DL, the modulation applied to the TFCI code word bits is the same as that applied to the data symbols. In UL, independent of the SF that is applied to the data symbols in the burst, the data in the TFCI field are always spread with SF= using the channelisation code in the branch with the highest code numbering of the allowed OVSF sub tree, as depicted in []. Hence the midamble structure and length is not changed. The TFCI code word is to be transmitted directly adjacent to the midamble, possibly after the TPC. Figure 7 shows the position of the TFCI code word in a traffic burst in downlink. Figure shows the position of the TFCI code word in a traffic burst in uplink.

3GPP TS 25.221 version.5.0 Release 23 TS 125 221 V.5.0 (2009-06) In case the Node B receives an invalid TFI combination on the DCHs mapped to one CCTrCH the procedure described in [] shall be applied. According to this procedure DTX shall be applied to all DPCHs to which the CCTrCH is mapped to. 5.2.2.5 Transmission of TPC Burst types 1, 2 and 3 for dedicated channels provide the possibility for transmission of TPC in uplink. The transmission of TPC is done in the data parts of the traffic burst. Independent of the SF that is applied to the data symbols in the burst, the data in the TPC field are always spread with SF= using the channelisation code in the branch with the highest code numbering of the allowed OVSF sub tree, as depicted in []. Hence the midamble structure and length is not changed. The TPC information is to be transmitted directly after the midamble. Figure 11 shows the position of the TPC in a traffic burst. For every user the TPC information shall be transmitted at least once per transmitted frame. If a TFCI is applied for a CCTrCH, TPC shall be transmitted with the same channelization codes and in the same timeslots as the TFCI. If no TFCI is applied for a CCTrCH, TPC shall be transmitted using the physical channel corresponding to physical channel sequence number p=1. Physical channel sequence numbering is determined by the rate matching function and is described in [7].

The TPC field is formed via repetition encoding a single bit b TPC, N TPC times. The relationship between b TPC and the TPC command is shown in table B. Table B: TPC bit pattern b TPC TPC command Meaning 0 'Down' Decrease Tx Power 1 'Up' Increase Tx Power 5.2.2.6 Timeslot formats 5.2.2.6.1 Downlink timeslot formats The downlink timeslot format depends on the spreading factor, midamble length and on the number of the TFCI code word bits, as depicted in the table 5a. For MBSFN operation the timeslot format also depends upon the symbol modulation scheme used. Slot formats 20-27 are only applicable to MBSFN operation with burst type.
