7.5 Adjacent Channel Selectivity (ACS) and narrow-band blocking
36.1413GPPBase Station (BS) conformance testingEvolved Universal Terrestrial Radio Access (E-UTRA)Release 17TS
7.5.1 Definition and applicability
Adjacent channel selectivity (ACS) is a measure of the receiver’s ability to receive a wanted signal at its assigned channel frequency in the presence of an adjacent channel signal with a specified centre frequency offset of the interfering signal to the band edge of a victim system.
The interfering signal shall be an E-UTRA signal as specified in Annex C.
Unless otherwise stated, a BS declared to be capable of E-UTRA with NB-IoT in-band and guard band operations is only required to pass the ACS and narrow-band blocking receiver tests for E-UTRA with guard band operation; it is not required to perform the ACS and narrow-band blocking receiver tests again for E-UTRA with in-band operation.
7.5.2 Minimum Requirement
The minimum requirement is in TS 36.104 [2] subclause 7.5.
7.5.3 Test purpose
The test purpose is to verify the ability of the BS receiver filter to suppress interfering signals in the channels adjacent to the wanted channel.
