3.1           Definitions
For the purposes of the present document, the following terms and definitions apply:
Donor coupling loss: is the coupling loss between the repeater and the donor base station.
Down-link: Signal path where base station transmits and mobile receives.
Pass band: The repeater can have one or several pass bands. The pass band is the frequency range that the repeater
operates in with operational configuration. This frequency range can correspond to one or several consecutive nominal
5 MHz channels. If they are not consecutive each subset of channels shall be considered as an individual pass band.
Repeater: A device that receives, amplifies and transmits the radiated or conducted RF carrier both in the down-link
direction (from the base station to the mobile area) and in the up-link direction (from the mobile to the base station)
Up-link: Signal path where mobile transmits and base station receives.

3.3           Abbreviations
For the purposes of the present document, the following abbreviations apply:
4             General
This specification applies only to UTRA-FDD repeaters.
Unless otherwise stated, all requirements in this specification apply to both the up-link and down-link directions.
The measurement results returned by the Test System are compared - without any modification - against the Test
Requirements as defined by the shared risk principle.
The Shared Risk principle is defined in ETR 273 Part 1 sub-part 2 section 6.5.[4]

Release 6                                                   8                         3GPP TS 25.106 V6.2.0 (2004-09)
                                                           3GPP
Release 6                                                    9                          3GPP TS 25.106 V6.2.0 (2004-09)
b) A UTRA/FDD repeater can support both fixed and variable up-link to down-link frequency separation.
    c) The use of other up-link to down-link frequency separations in existing or other frequency bands shall not be
       precluded.
6             Output power
Output power, Pout, of the repeater is the mean power of one carrier at maximum repeater gain delivered to a load with
resistance equal to the nominal load impedance of the transmitter.
Rated output power, PRAT, of the repeater is the mean power level per carrier at maximum repeater gain that the
manufacturer has declared to be available at the antenna connector.
                                                            3GPP
Release 6                                                   10                          3GPP TS 25.106 V6.2.0 (2004-09)
When the power of all signals is increased by 10 dB, compared to the power level that produce the maximum rated
output power, the requirements shall still be met.
In normal conditions, the Repeater maximum output power shall remain within limits specified in Table 6.1 relative to
the manufacturer's rated output power.
In extreme conditions, the Repeater maximum output power shall remain within the limits specified in Table 6.2
relative to the manufacturer's rated output power.
In certain regions, the minimum requirement for normal conditions may apply also for some conditions outside the
ranges of conditions defined as normal.
7             Frequency stability
Frequency stability is the ability to maintain the same frequency on the output signal with respect to the input signal.
                                                          3GPP
Release 6                                                    11                         3GPP TS 25.106 V6.2.0 (2004-09)
The repeater minimum donor coupling loss shall be declared by the manufacturer. This is this the minimum required
attenuation between the donor BS and the repeater for proper repeater operation.
The gain outside the pass band shall not exceed the maximum level specified in table 8.1, where:
- f_offset is the distance from the centre frequency of the first or last 5 MHz channel within the pass band.
For 12,5 MHz ≤ f_offset the out of band gain shall not exceed the maximum gain of table 8.2 or the maximum gain
stated in table 8.1 whichever is lower.
9 Unwanted emission
For regions where this clause applies, the requirement shall be met by a repeater's RF-signal output at maximum gain
with WCDMA signals in the pass band of the repeater, at levels that produce the maximum rated output power per
channel. The requirements shall also apply at maximum gain without WCDMA signals in the pass band.
Emissions shall not exceed the maximum level specified in tables 9.1 to 9.4 for the appropriate repeater maximum
output power, in the frequency range from ∆f = 2,5 MHz to ∆fmax from the 5 MHz channel, where:
    -   ∆f is the separation between the centre frequency of first or last 5 MHz channel used in the pass band and the
        nominal –3 dB point of the measuring filter closest to the carrier frequency.
    -   f_offset is the separation between the centre frequency of first or last 5 MHz channel in the pass band and the
        centre of the measuring filter.
    -   f_offsetmax is either 12,5 MHz or the offset to the UTRA band edge at both up- and down-link as defined in
        section 5.1, whichever is the greater.
- ∆f max is equal to f_offsetmax minus half of the bandwidth of the measurement filter.

11            Input Intermodulation
The input intermodulation is a measure of the capability of the repeater to inhibit the generation of interference in the
pass band, in the presence of interfering signals on frequencies other than the pass band.
The frequency separation between the two interfering signals shall be adjusted so that the 3rd order intermodulation
product is positioned in the centre of the pass band.
Table 11.1 specifies the parameters for two interfering signals, where:
   −    f_offset is the separation between the centre frequency of first or last 5 MHz channel in the pass band and one
        the interfering signals.
The frequency separation between the two interfering signals shall be adjusted so that the lowest order intermodulation
product is positioned in the centre of the pass band.
   NOTE 1: The lowest intermodulation products corresponds to the 4th and 3rd order for the GSM 900 and DCS 1800
           bands, respectively.

The frequency separation between the two interfering signals shall be adjusted so that the lowest order intermodulation
product is positioned in the centre of the pass band.
   NOTE 1: The lowest intermodulation products corresponds to the 4th and 3rd order for the GSM 900 and DCS 1800
           bands, respectively.

12            Output intermodulation
The output intermodulation requirement is a measure of the ability of the repeater to inhibit the generation of
intermodulation products signals created by the presence of an interfering signal reaching the repeater via the output
port.
The output intermodulation level is the power of the intermodulation products when a WCDMA modulated interference
signal is injected into the output port at a level of 30 dB lower than that of the wanted signal. The frequency of the
interference signal shall be ±5 MHz, ±10 MHz and ±15 MHz offset from the wanted signal, but within the frequency
band allocated for UTRA FDD downlink as specified in subclause 4.1.

The requirement shall apply to the Uplink and Downlink of Repeater where the donor link is maintained via antennas
(over the air Repeater).
