11 Input Intermodulation
25.1063GPPRelease 17TSUTRA repeater radio transmission and reception
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.
11.1 General Requirement
The following requirement applies for interfering signals in the frequency bands defined in sub-clause 5.1, depending on the repeaters pass band. The requirement shall bet met with the repeater operating at maximum gain.
11.1.1 Minimum requirement
For the parameters specified in table 11.1, the power in the pass band, shall not increase with more than 10 dB at the output of the repeater as measured in the centre of the pass band, compared to the level obtained without interfering signals applied.
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.

11.2 Co-location with BS in other systems
The requirement shall bet met with the repeater operating at maximum gain.
11.2.1 Minimum requirements – Co-location with GSM, DCS, PCS, UTRA FDD and/or E-UTRA FDD
This additional input intermodulation requirement may be applied for the protection of FDD Repeater input when GSM900, DCS1800, PCS1900, GSM850, E-UTRA FDD and/or UTRA FDD BS are co-located with a UTRA FDD Repeater.
For the parameters specified in table 11.2, the power in the pass band shall not increase with more than 10 dB at the output of the repeater as measured in the centre of the pass band, compared to the level obtained without interfering signals applied.
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 product corresponds to the 4th and 3rd order for the GSM 900 and DCS 1800 bands, respectively.

NOTE 1: The co-location requirements in the table 11.2 do not apply when the repeaters pass band frequency range is adjacent to the frequency range of the co-location requirement in the table 11.2. The current state-of-the-art technology does not allow a single generic solution for co-location with other system on adjacent frequencies for 30 dB Repeater-BS minimum coupling loss. However, there are certain site-engineering solutions that can be used. These techniques are addressed in TR 25.942 [5]. NOTE 2: The table above assumes that two operating bands, where the frequency ranges would be overlapping, are not deployed in the same geographical area. For such a case of operation with overlapping frequency arrangements in the same geographical area, special co-existence requirements may apply that are not covered by the 3GPP specifications. |
11.2.2 Minimum Requirement – Co-location with UTRA-TDD and/or E-UTRA TDD
An additional input intermodulation requirement may be applied for the protection of FDD BS receivers when UTRA TDD and/or E-UTRA TDD is co-located with a UTRA FDD Repeater.
The requirements in this chapter assume a 30 dB coupling loss between transmitter and receiver.
The current state-of-the-art technology does not allow a single generic solution for co-location with UTRA-TDD on adjacent frequencies for 30dB BS-Repeater minimum coupling loss.
However, there are certain site-engineering solutions that can be used. These techniques are addressed in TR 25.942 [5].

NOTE 1: The co-existence requirements in Table 11.3A do not apply when the repeaters pass band frequency range is adjacent to the frequency range of the co-location requirement in the Table 11.3A. The current state-of-the-art technology does not allow a single generic solution for co-location with other system on adjacent frequencies for 30 dB Repeater-BS minimum coupling loss. However, there are certain site-engineering solutions that can be used. These techniques are addressed in TR 25.942 [5] NOTE 2: The table above assumes that two operating bands, where the frequency ranges would be overlapping, are not deployed in the same geographical area. For such a case of operation with overlapping frequency arrangements in the same geographical area, special co-existence requirements may apply that are not covered by the 3GPP specifications. |
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 is applicable for downlink signals.
12.1 Minimum requirement
The output intermodulation level shall not exceed the out of band emission or the spurious emission requirements of section 9.1 and 9.2.
