7.4 Adjacent channel selectivity and narrowband blocking
37.145-13GPPActive Antenna System (AAS) Base Station (BS) conformance testingPart 1: conducted conformance testingRelease 17TS
7.4.1 Definition and applicability
The adjacent channel selectivity, general blocking and narrowband blocking characteristics are measures of the receiver unit ability to receive a wanted signal at its assigned channel at the TAB connector in the presence of an unwanted interferer inside the operating band.
NOTE For Single RAT requirements, the in-band selectivity characteristics is referred to as "adjacent channel selectivity", whereas for the MSR requirements, the corresponding property is referred to as "general blocking" since the adjacent frequency range may not carry a channel addressable from the interfered carrier.
The in-band blocking requirement applies from FUL_low – ΔfOOB to FUL_high + ΔfOOB, excluding the downlink frequency range of the operating band. The values of ΔfOOB are defined in table 7.4.1-1.

NOTE: If the above Test Requirement differs from the Minimum Requirement then the Test Tolerance applied for this test is non-zero. The Test Tolerance for this test is defined in clause 4.1.2 and the explanation of how the Minimum Requirement has been relaxed by the Test Tolerance is given in annex C.
