 MHz range outside of the operating band for the base stations and within 15 MHz range of the operating band for the devices. These scenarios are modeled with a continuous wave (CW) signal for the out-of-band case and an NR signal for the in-band case. There are additional BS blocking requirements for the scenario in which the BS is co-located with another BS in a different operating band. For the UEs, a number of exceptions from the out-of-band blocking requirements are allowed, where the device is required to comply with more relaxed spurious response requirements. For a BS operating in non-contiguous spectrum in any operating bands, the in-band blocking requirements further apply in subblock gaps, if the subblock gap size is at least twice as wide as the interfering signal minimum offset. The interfering signal offset is defined relative to the subblock edges inside the subblock gap. For a multi-band connec- tor, the blocking requirements apply in the in-band blocking frequency ranges for each supported operating band. For a BS operating in non-contiguous spectrum within any operating bands, the narrowband blocking requirements are further applied within the sub- block gap, if the subblock gap size is at least as wide as the channel bandwidth of the NR 690 Chapter 5 interfering signal. The interfering signal offset is defined relative to the subblock edges inside the subblock gap. For a multi-band connector the narrowband blocking requirement is further applied inside any inter-RF bandwidth gap, 6 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. Adjacent Channel Selectivity (ACS): This is a measure of the receiver's ability to receive a desired signal in its assigned channel frequency at the antenna connector for BS type 1-C or TAB connector for BS type 1-H in the presence of an adjacent channel signal with a specified center frequency offset from
