Introduction With participation of radio communication equipment manufacturers, broadcasting equipment manufacturers, telecommunication operators, broadcasters and general equipment users, Association of Radio Industries and Businesses (ARIB) defines basic technical requirements for standard specifications of radio equipment, etc. as an "ARIB STANDARD" in the field of various radio systems. In conjunction with national technical standards which are intended for effective spectrum utilization and avoidance of interference with other spectrum users, an ARIB STANDARD is intended as a standard for use by a private sector compiling various voluntary standards regarding the adequate quality of radio and broadcasting service, compatibility issues, etc., and aims to enhance conveniences for radio equipment manufacturers, telecommunication operators, broadcasting equipment manufacturers, broadcasters and general users. A ARIB STANDARD herein is published as "THE LOW POWER REPEATERS FOR DS-CDMA/LTE" In order to ensure fairness and transparency in the defining stage, the standard was set by consensus of the standard council with participation of interested parties including radio equipment manufacturers, telecommunication operators, broadcasters, testing organizations, general users, etc. with impartiality. It is our sincere hope that the standard would be widely used by radio equipment manufacturers, testing organizations, general users, etc.

Chapter 10 Modulation accuracy 10.1 Requirements for DS-CDMA Repeater 10.1.1 Error Vector Magnitude The modulation accuracy is defined by the Error Vector Magnitude (EVM), which is a measure of the difference between the theoretical waveform and a modified version of the measured waveform. This difference is called the error vector. The measured waveform is modified by first passing it through a matched root raised cosine filter with bandwidth 3.84 MHz and roll-off α=0.22. The waveform is then further modified by selecting the frequency, absolute phase, absolute amplitude and chip clock timing so as to minimise the error vector. The EVM result is defined as root of the ratio of the mean error vector power to the mean reference signal power expressed as a %. The measurement interval is one power control group (timeslot). The repeater shall operate with an ideal WCDMA signal in the pass band of the repeater at a level, which produce the maximum rated output power per channel, as specified by the manufacturer. 10.1.1.1 Test requirement The Error Vector Magnitude shall not be worse than 12,5 %. 10.1.2 Peak code domain error The peak code domain error is computed by projecting the power of the error vector (as defined in subclause 10.1) onto the code domain at a specified spreading factor. The code domain error for every code in the domain is defined as the ratio of the mean power of the projection onto that code, to the mean power of the composite reference waveform. This ratio is expressed in db. The peak code domain error is defined as the maximum value for the code domain error for all codes. The measurement interval is one power control group (timeslot). 10.1.2.1 Test requirement The peak code domain error shall not exceed -35 db at spreading factor 256. 10.2 Requirements for LTE Repeater 10.2.1 Downlink Error Vector Magnitude The Error Vector Magnitude is a measure of the difference between the ideal symbols and the measured symbols after the equalization. This difference is called the error vector. The equalizer parameters are estimated as defined in TS36.104 [2] Annex E. The EVM result is defined as the square root of the ratio of the mean error vector power to the mean reference -25-
power expressed in percent. 10.2.1.1 Test requirement For all E-UTRA channel bandwidths, as defined in sub-clause 5.3, applicable to the repeater, the EVM measurement shall be performed over all allocated resource blocks and subframes within a frame. The EVM value is then calculated as the mean square root of the measured values. For the downlink of the repeater the Error Vector Magnitude shall not be worse than [8% + 1.25%]. 10.2.2 Uplink Error Vector Magnitude The Error Vector Magnitude is a measure of the difference between the reference waveform and the measured waveform. This difference is called the error vector. Before calculating the EVM the measured waveform is corrected by the sample timing offset and RF frequency offset. Then the IQ origin offset shall be removed from the measured waveform before calculating the EVM. The measured waveform is further modified by selecting the absolute phase and absolute amplitude of the Tx chain. The EVM result is defined after the front-end IDFT as the square root of the ratio of the mean error vector power to the mean reference power expressed as a %. The basic EVM measurement interval is one slot in the time domain. 10.2.2.1 Test requirement For the uplink of the repeater the RMS average of the basic EVM measurements for 10 consecutive sub-frames for the different modulations schemes shall not exceed [8% + 1.25%]. -26-
