7.8.1 General

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 or more interfering signals which have a specific frequency relationship to the wanted signal

7.8.2 Wide band Intermodulation

The wide band intermodulation requirement is defined using a CW carrier and modulated NR signal as interferer 1 and interferer 2 respectively.

The throughput shall be ≥ 95 % of the maximum throughput of the reference measurement channels as specified in Annexes A.2.2, A.3.2 and A.3.3 (with one sided dynamic OCNG Pattern OP.1 FDD/TDD for the DL-signal as described in Annex A.5.1.1/A.5.2.1) with parameters specified in Table 7.8.2-1 for NR bands with F_{DL_high} < 2700 MHz and F_{UL_high} < 2700 MHz and Table 7.8.2-2 for NR bands with F_{DL_low} ≥ 3300 MHz and F_{UL_low} ≥ 3300 MHz. The relative throughput requirement shall be met for any SCS specified for the channel bandwidth of the wanted signal. For operating bands with an unpaired DL part (as noted in Table 5.2-1), the requirements only apply for carriers assigned in the paired part.

F_{Interferer 2} (Offset)	MHz		2*F_{Interferer 1}
NOTE 1: The transmitter shall be set to 4 dB below P_{CMAX_L,f,c}at the minimum UL configuration specified in Table 7.3.2-3 with P_{CMAX_L,f,c}defined in clause 6.2.4. NOTE 2: Reference measurement channel is specified in Annexes A.2.2, A.3.2, and A.3.3 (with one sided dynamic OCNG Pattern OP.1 FDD/TDD for the DL-signal as described in Annex A.5.1.1/A.5.2.1). NOTE 3: The modulated interferer consists of the Reference measurement channel specified in Annexes A.3.2.2 and A.3.3.2 with one sided dynamic OCNG Pattern OP.1 FDD/TDD for the DL-signal as described in Annex A.5.1.1/A.5.2.1 and 15 kHz SCS. NOTE 4: The F_{interferer 1}(offset) is the frequency separation of the center frequency of the carrier closest to the interferer and the center frequency of the CW interferer and F_interferer ₂ (offset) is the frequency separation of the center frequency of the carrier closest to the interferer and the center frequency of the modulated interferer. NOTE 5: 10log₁₀(x) is rounded to the next higher 0.5dB value.

NOTE 4: The F_{interferer 1}(offset) is the frequency separation of the center frequency of the carrier closest to the interferer and the center frequency of the CW interferer and F_interferer ₂ (offset) is the frequency separation of the center frequency of the carrier closest to the interferer and the center frequency of the modulated interferer.
