7.8 Receiver intermodulation

36.1043GPPBase Station (BS) radio transmission and receptionEvolved Universal Terrestrial Radio Access (E-UTRA)Release 18TS

Third and higher order mixing of the two interfering RF signals can produce an interfering signal in the band of the desired channel. Intermodulation response rejection is a measure of the capability of the receiver to receive a wanted signal on its assigned channel frequency in the presence of two interfering signals which have a specific frequency relationship to the wanted signal. Interfering signals shall be a CW signal and an E-UTRA signal as specified in Annex C.

7.8.1 Minimum requirement

For E-UTRA, the throughput shall be ≥ 95% of the maximum throughput of the reference measurement channel, with a wanted signal at the assigned channel frequency and two interfering signals coupled to the BS antenna input, with the conditions specified in Tables 7.8.1-1 and 7.8.1-2 for intermodulation performance and in Tables 7.8.1-3, 7.8.1-4, 7.8.1-5 and 7.8.1-6 for narrowband intermodulation performance. Narrowband intermodulation requirements are not applied for Band 46. The reference measurement channel for the wanted signal is identified in Table 7.2.1-1, Table 7.2.1-2, Table 7.2.1-3 and Table 7.2.1-4 for each channel bandwidth and further specified in Annex A.

For NB-IoT in-band operation, the throughput shall be ≥ 95% of the maximum throughput of the reference measurement channel, with a wanted signal at the assigned channel frequency and two interfering signals coupled to the BS antenna input, with the conditions specified in Tables 7.8.1-1a and 7.8.1-2 for intermodulation performance and in Tables 7.8.1-3a, 7.8.1-4a, 7.8.1-5a and 7.8.1-6a for narrowband intermodulation performance. The reference measurement channel for the wanted signal is identified in Tables 7.2.1-5, 7.2.1-5a, 7.2.1-5b and 7.2.1-5c and further specified in Annex A.

For NB-IoT guard band operation, the throughput shall be ≥ 95% of the maximum throughput of the reference measurement channel, with a wanted signal at the assigned channel frequency and two interfering signals coupled to the BS antenna input, with the conditions specified in Tables 7.8.1-1b and 7.8.1-2 for intermodulation performance and in Tables 7.8.1-3b, 7.8.1-4b, 7.8.1-5b and 7.8.1-6b for narrowband intermodulation performance. The reference measurement channel for the wanted signal is identified in Tables 7.2.1-5, 7.2.1-5a, 7.2.1-5b and 7.2.1-5c and further specified in Annex A.

For NB-IoT standalone operation, the throughput shall be ≥ 95% of the maximum throughput of the reference measurement channel, with a wanted signal at the assigned channel frequency and two interfering signals coupled to the BS antenna input, with the conditions specified in Tables 7.8.1-1c and 7.8.1-2a for intermodulation performance and in Tables 7.8.1-3c, 7.8.1-4c, 7.8.1-5c and 7.8.1-6c for narrowband intermodulation performance. The reference measurement channel for the wanted signal is identified in Tables 7.2.1-5, 7.2.1-5a and 7.2.1-5c and further specified in Annex A.

The receiver intermodulation requirement is applicable outside the Base Station RF Bandwidth or Radio Bandwidth edges. The interfering signal offset is defined relative to the Base Station RF Bandwidth edges or Radio Bandwidth edges.

For a BS operating in non-contiguous spectrum within any operating band, the narrowband intermodulation requirement applies in addition inside any sub-block gap in case the sub-block gap is at least as wide as the channel bandwidth of the E-UTRA interfering signal in Table 7.8.1-3. The interfering signal offset is defined relative to the sub-block edges inside the sub-block gap.

For a BS capable of multi-band operation, the intermodulation requirement applies in addition inside any Inter RF Bandwidth gap, in case the gap size is at least twice as wide as the E-UTRA interfering signal centre frequency offset from the Base Station RF Bandwidth edge.

For a BS capable of multi-band operation, the narrowband intermodulation requirement applies in addition inside any Inter RF Bandwidth gap in case the gap size is at least as wide as the E-UTRA interfering signal in Tables 7.8.1-3, 7.8.1-4 and 7.8.1-6. The interfering signal offset is defined relative to the Base Station RF Bandwidth edges inside the Inter RF Bandwidth gap.

Note*: PREFSENS depends on the sub-carrier spacing as specified in Table 7.2.1-5c.

Note**: Interfering signal consisting of one resource block positioned at the stated offset, the channel bandwidth of the interfering signal is located adjacently to the lower/upper Base Station RF Bandwidth edge.

Note***: This requirement shall apply only for a FRC A1-3 mapped to the frequency range at the channel edge adjacent to the interfering signals.

Note****: The frequency offset shall be adjusted to accommodate the IMD product to fall in the NB-IoT RB for NB-IoT guard band operation.

Note*****: If a BS RF receiver fails the test of the requirement, the test shall be performed with the CW interfering signal frequency shifted away from the wanted signal by 180 kHz and the E-UTRA interfering signal frequency shifted away from the wanted signal by 360 kHz. If the BS RF receiver still fails the test after the frequency shift, then the BS RF receiver shall be deemed to fail the requirement.
