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.

5.4 UTRA Channel arrangement
5.4.1 UTRA Channel spacing
The nominal channel spacing is 5 MHz, but this can be adjusted to optimize performance in a
particular deployment scenario.
5.4.2 UTRA Channel raster
The channel raster is 200 kHz for all bands, which means that the centre frequency must be an integer multiple of 200 kHz. In addition, a number of additional centre frequencies are
specified according to the Table 5-6 which means that and the centre frequencies for these
channels are shifted 100 kHz relative to the general raster.
5.4.3 UTRA Channel number
The carrier frequency is designated by the UTRA Absolute Radio Frequency Channel
Number (UARFCN).
For each operating band, the UARFCN values are defined as follows. Uplink: NU = 5 * (FUL - FUL_Offset), for the carrier frequency range FUL_low ≤ FUL ≤ FUL_high
Downlink: ND = 5 * (FDL - FDL_Offset), for the carrier frequency range FDL_low ≤ FDL ≤ FDL_high
For each operating Band, FUL_Offset, FUL_low, FUL_high, FDL_Offset, FDL_low and FDL_high are defined
in Table 5-6 for the general UARFCN. For the additional UARFCN, FUL_Offset, FDL_Offset and the

5.5 E-UTRA Channel arrangement
5.5.1 E-UTRA Channel spacing
The spacing between carriers will depend on the deployment scenario, the size of the
frequency block available and the channel bandwidths. The nominal channel spacing between
ARIB STD-T63-25.A01 V10.1.0
-10-
two adjacent E-UTRA carriers is defined as following: Nominal Channel spacing = (BWChannel(1) + BWChannel(2))/ 2
where BWChannel(1) and BWChannel(2) are the channel bandwidths of the two respective
E-UTRA carriers. The channel spacing can be adjusted to optimize performance in a particular
deployment scenario.
5.5.2 E-UTRA Channel raster
The channel raster is 100 kHz for all bands, which means that the carrier centre frequency
must be an integer multiple of 100 kHz.
5.5.3 E-UTRA Carrier frequency and EARFCN
The carrier frequency in the uplink and downlink is designated by the E-UTRA Absolute
Radio Frequency Channel Number (EARFCN) in the range 0 - 65535. The relation between
EARFCN and the carrier frequency in MHz for the downlink is given by the following equation, where FDL_low and NOffs-DL are given in Table 5-8 and NDL is the downlink EARFCN.
FDL = FDL_low + 0.1(NDL – NOffs-DL)
The relation between EARFCN and the carrier frequency in MHz for the uplink is given by the following equation where FUL_low and NOffs-UL are given in Table 5-8 and NUL is the uplink
EARFCN. FUL = FUL_low + 0.1(NUL – NOffs-UL)

emissions. This out of band emission requirement is specified in terms of a spectrum emission
mask.
9.1.1 Occupied bandwidth
The occupied bandwidth is the width of a frequency band such that, below the lower and
above the upper frequency limits, the mean powers emitted are each equal to a specified
percentage β/2 of the total mean transmitted power. See also ITU-R Recommendation SM.328 [7]. The value of β/2 shall be taken as 0.5%.
9.1.1.1 Minimum Requirement
The occupied channel bandwidth of UTRA shall be less than 5 MHz.
The occupied channel bandwidth of E-UTRA shall be less than the channel bandwidth as defined in Table 5-5.
9.1.2 Adjacent Channel Leakage power Ratio (ACLR)
Adjacent Channel Leakage power Ratio (ACLR) is the ratio of the RRC (3.84 Mcps) filtered mean power centered on the assigned channel frequency to the RRC filtered mean power
centered on an adjacent channel frequency.
The requirements shall apply whatever the type of transmitter considered (single carrier or
multi-carrier). It applies for all transmission modes foreseen by the manufacturer's
specification.
9.1.2.1 Uplink test requirements
The ACLR shall be higher than the value specified in Table 9-1. For UTRA band I, VI or XIX

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
ARIB STD-T63-25.A01 V10.1.0
-26-
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%].

that appear at the receiver antenna connector of repeater. The requirements apply to all
repeater with separate RX and TX antenna port. The test shall be performed when both TX and
RX are on with the TX port terminated.
For all repeater with common RX and TX antenna port the transmitter spurious emission as specified in section 9.2 is valid.
