1 Scope
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.
