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.

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.

5.5 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

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)

NOTE: The channel numbers that designate carrier frequencies so close to the operating band edges that

the carrier extends beyond the operating band edge shall not be used. This implies that the first 25 channel

numbers at the lower operating band edge and the last 24 channel numbers at the upper operating band edge

shall not be used for channel bandwidths of 5 MHz respectively.

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 shall be less than 5 MHz.

9.1.2 Adjacent Channel Leakage power Ratio (ACLR)

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).


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 V9.2.0

-24-

power expressed in percent.


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.


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%].

Chapter 11 Receiver spurious emissions The spurious emissions power is the power of emissions generated or amplified in a receiver

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.

11.1 Test requirements

The power of any spurious emission shall not exceed the maximum level specified in Table

11-1 and Table 11-2.
