Universal Mobile Telecommunications System (UMTS); LTE; Active Antenna System (AAS) Base Station (BS) Electromagnetic Compatibility (EMC) (V15.4.0; 3GPP TS 37.114 version 15.4.0 Release 15)
The present document covers the assessment of UTRA TDD@ UTRA FDD@ E-UTRA@ NR and Multi-Standard Radio (MSR) Active Antenna Systems Base Stations in respect of Electromagnetic Compatibility (EMC). NOTE 1: Whenever the AAS BS in single RAT UTRA operation@ or AAS BS in MSR operation using UTRA is referred in this specification@ UTRA TDD and UTRA FDD shall be considered@ unless otherwise stated. NOTE 2: For NR@ scope of this specification is limited to BS type 1-H and BS type 1-O. For EMC requirements of the MSR BS for BS type 1-C@ refer to TS 37.113 [4]. The present document specifies the applicable test conditions@ performance assessment and performance criteria for base stations in the following categories: - Active Antenna System Base Station for UTRA TDD@ UTRA FDD@ E-UTRA@ NR and MSR meeting the conducted requirements of TS 37.105 [2]@ with conformance demonstrated by compliance to TS 37.145-1 [3]@ - Active Antenna System Base Station for UTRA FDD@ E-UTRA@ NR and MSR meeting the OTA requirements of 3TS 37.105 [2]@ with conformance demonstrated by compliance to TS 37.145-2 [10]. The present document does not cover ancillary equipment requirements@ where ancillary equipment is not incorporated in the radio equipment and can be assessed on a stand-alone basis@ as declared by the manufacturer. Ancillary equipment EMC requirements are still applicable to the AAS BS and are covered by other EMC specifications in TS 25.113 [5]@ TS 36.113 [6]@ TS 37.113 [4] or TS 38.113 [30]. The present document does not specify test conditions@ performance assessment and performance criteria for the 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 36.113 [6]@ or for AAS BS in MSR operation using E-UTRA as defined in TS 37.113 [4]. The present document does not specify test conditions@ performance assessment and performance criteria for Band 46 operation as it is not supported by AAS BS. The scope of the present document is twofold: - Requirement@ procedures and values of a hybrid AAS BS with TAB connectors for every transceiver unit at the transceiver array boundary (TAB)@ subject to conducted requirements@ NOTE 3: hybrid AAS BS in the single RAT NR operation is equivalent to BS type 1-H defined in NR BS specification TS 38.104 [31]. - Requirements@ procedures and values of an OTA AAS BS without TAB connectors and relying in the radiated interface@ subject to radiated requirements. NOTE 4: OTA AAS BS in the single RAT NR operation is equivalent to BS type 1-O defined in NR BS specification TS 38.104 [31]. The electromagnetic environment classification used in the present document refers to the residential@ commercial and light industrial environment classification used in IEC 61000-6-1 [7] and IEC 61000-6-3 [8]. The EMC requirements have been selected to ensure an adequate level of compatibility for apparatus at residential@ commercial and light industrial environments. The levels@ however@ do not cover extreme cases which may occur in any location but with low probability of occurrence.
