scope:
The present document specifies technical characteristics and methods of measurements for types of radio equipment:
• AAS BS supporting Single-RAT UTRA FDD.
• AAS BS supporting Single-RAT E-UTRA.
• AAS BS supporting Multi-Standard Radio (UTRA-FDD, E-UTRA, NR).
In the present document, the term "requirements for single RAT operation" refers to requirements that are derived from the ETSI TS 125 141 [7] or ETSI TS 136 141 [11] specifications baseline. The term "requirements for MSR operation" refers to requirements derived from the ETSI TS 137 141 [6] specification baseline (including NR operation as part of MSR).
These radio equipment types are capable of operating in whole or any part of the frequency band(s) given in table 1-1.
NOTE 1: For BS capable of multi-band operation, the supported operating bands may belong to different Band Categories.
NOTE 2: AAS BS does not support GSM/EDGE, but BC2 is still applicable for protection of/against GSM/EDGE operation in BC2 operating bands.
NOTE 3: AAS BS does not support Narrow-Band Internet of Things (NB-IoT) in band, NB-IoT guard band, or standalone NB-IoT operation, but NB-IoT limits are still applicable for AAS BS protection of/against NB-IoT operation in operating bands.
NOTE 4: AAS BS does not support band 46 operation, but band 46 limits are still applicable for AAS BS protection of/against devices operating in band 46.
NOTE 5: The band categories for BS are defined in clause 4.4 of ETSI TS 137 141 [6] and are listed in table 1-1.
AAS BS supports carrier aggregation as defined in tables 4.2.1-3 to 4.2.1-6 in ETSI EN 301 908-14 [5], or tables 4.2.1-2 to 4.2.1-7 in ETSI EN 301 908-18 [4], except for the CA combinations involving band 46.
The present document covers conducted and radiated requirements for AAS BS capable of single-RAT UTRA, single-RAT E-UTRA and MSR multi-RAT operation (UTRA, E-UTRA, NR) in 3GPP™ Release 15. Additionally, it includes for selected AAS BS operating bands from 3GPP Release 16.
NOTE 6: The relationship between the present document and essential requirements of article 3.2 of Directive 2014/53/EU [i.2] is given in annex A.
