the interfering signal to the edge of the band of a victim system. For a BS operating in non-contiguous spectrum within any operating bands, the ACS requirement is further applied within the subblock gaps, in case the subblock gap size is at least as wide as the NR interfering signal. The interfer- ing signal offset is defined relative to the subblock edges inside the subblock gap. For a multi-band connector, the ACS requirement is applied within the inter-RF bandwidth gap, in case the inter-RF bandwidth gap size is at least as wide as the NR interfering signal. The interfering signal offset is defined relative to the base station RF bandwidth edges inside the inter-RF bandwidth gap. This corresponds to a scenario where there is a strong signal in the channel adjacent to the desired signal and is closely related to the corresponding ACLR requirement. The adjacent interferer is an NR signal. For the device, the ACS is specified for two cases with a lower and a higher signal level. In-Channel Selectivity (ICS): This is a measure of the receiver ability to receive a desired signal in its assigned resource block locations at the antenna connector for BS type 1-C or TAB connector for BS type 1-H in the presence of an interfering signal received with a larger power spectral density. Under this condition, certain throughput requirement (throughput must be greater than 95% of the maximum throughput of the reference measurement) must be met for a specified reference measurement channel. The interfering signal is an NR signal which is time-aligned with the desired signal. In other words, in this scenario, multiple signals with different power levels are received within the channel bandwidth, where the performance of the weaker desired signal is verified in the presence of the stronger interfering signal. The ICS requirement is only specified for the base stations (see Fig. 5.10). Receiver Intermodulation: The third and higher order harmonics resulted from mixing of the two interfering RF signals can produce an interfering
