1 Scope p. 7

The present document covers the assessment of NR, E-UTRA, UTRA, GSM/EDGE and NB-IoT Multi-Standard Radio (MSR) Base Stations and associated ancillary equipment in respect of Electromagnetic Compatibility (EMC).

The present document specifies the applicable test conditions, performance assessment and performance criteria for NR, E-UTRA, UTRA, GSM/EDGE and NB-IoT Base Stations and associated ancillary equipment in one of the following categories:

Multi-Standard Radio (MSR) Base Stations for NR, E-UTRA, UTRA and GSM/EDGE meeting the requirements of TS 37.104, with conformance demonstrated by compliance to TS 37.141.

NOTE:
For NR, scope of this specification is limited to BS type 1-C. For EMC requirements of the MSR BS for BS type 1-H and BS type 1-O, refer to TS 37.114.
BS type 1-C for NR meeting the requirements of TS 38.104, with conformance demonstrated by compliance to TS 38.141-1
Base Stations for E-UTRA meeting the requirements of TS 36.104, with conformance demonstrated by compliance to TS 36.141.
Base Stations for UTRA FDD meeting the requirements of TS 25.104, with conformance demonstrated by compliance to TS 25.141.
Base Stations for UTRA TDD meeting the requirements of TS 25.105, with conformance demonstrated by compliance to TS 25.142.
Base Stations for GSM/EDGE meeting the requirements of TS 45.005, with conformance demonstrated by compliance to TS 51.021.
Base Stations for NB-IoT meeting the requirements of TS 36.104, with conformance demonstrated by compliance to TS 36.141.

In addition to MSR base stations, the present document covers other BS supporting more than one RAT.

Technical requirements related to the antenna port of Base Stations are not included in the present document. These are found in the relevant product standards [2-11, 35, 36].

The environment classification used in the present document refers to the residential, commercial, and light industrial environment classification used in IEC 61000-6-1 [12] and IEC 61000-6-3 [13].

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.

Equipment (apparatus), used in connection with a receiver, transmitter or transceiver is considered as an ancillary equipment (apparatus) if:

the equipment is intended for use in conjunction with a receiver, transmitter or transceiver to provide additional operational and/or control features to the radio equipment, (e.g. to extend control to another position or location); and
the equipment cannot be used on a stand-alone basis to provide user functions independently of a receiver, transmitter or transceiver; and
the receiver, transmitter or transceiver to which it is connected, is capable of providing some intended operation such as transmitting and/or receiving without the ancillary equipment (i.e. it is not a sub-unit of the main equipment essential to the main equipment basic functions).

antenna connector:

connector at the conducted interface of the BS type 1-C

Band category:

group of operating bands for which the same MSR scenarios apply

Base Station equipment:
