Active Antenna System (AAS) Base Station (BS) conformance testing; Part 1: conducted conformance testing
The present document specifies the conducted test methods and conformance requirements for single RAT E-UTRA operation, single RAT UTRA operation (FDD and TDD) and Multi-Standard Radio (MSR) UTRA, E-UTRA and NR Active Antenna System (AAS) Base Station (BS). These have been derived from, and are consistent with the non-AAS BS specifications in TS 25.104 [2], TS 25.105 [3], TS 36.104 [4], TS 38.104 [36] or TS 37.104 [5]. The technical specification TS 37.145 is in 2 parts, part TS 37.145-1 (the present document) covers conducted requirements and part TS 37.145-2 [40] covers radiated requirements.
The present document does not establish conducted test methods and conformance requirements for Band 46 operation as it is not supported by AAS BS, but Band 46 test requirements are still applicable for AAS BS for protection of and against Band 46 operation.
The present document does not establish conducted test methods and conformance requirements for Narrow-Band Internet of Things (NB-IoT) in band, NB-IoT guard band, or standalone NB-IoT operation, for AAS BS in single RAT E-UTRA operation as defined in TS 36.141 [14], or for AAS BS in MSR operation using E-UTRA as defined in TS 37.141 [13].
