TSG approval. Should the TSG modify the contents of the present document, it will be re-released by the TSG with an
identifying change of release date and an increase in version number as follows:

z the third digit is incremented when editorial only changes have been incorporated in the document.
In the present document, modal verbs have the following meanings:
shall indicates a mandatory requirement to do something
shall not indicates an interdiction (prohibition) to do something
The constructions "shall" and "shall not" are confined to the context of normative provisions, and do not appear in
Technical Reports.
The constructions "must" and "must not" are not used as substitutes for "shall" and "shall not". Their use is avoided
insofar as possible, and they are not used in a normative context except in a direct citation from an external, referenced,
non-3GPP document, or so as to maintain continuity of style when extending or modifying the provisions of such a
referenced document.
should indicates a recommendation to do something
should not indicates a recommendation not to do something
may indicates permission to do something
need not indicates permission not to do something
The construction "may not" is ambiguous and is not used in normative elements. The unambiguous constructions
"might not" or "shall not" are used instead, depending upon the meaning intended.
can indicates that something is possible
cannot indicates that something is impossible
The constructions "can" and "cannot" are not substitutes for "may" and "need not".
will indicates that something is certain or expected to happen as a result of action taken by an
agency the behaviour of which is outside the scope of the present document
will not indicates that something is certain or expected not to happen as a result of action taken by an
agency the behaviour of which is outside the scope of the present document
might indicates a likelihood that something will happen as a result of action taken by some agency the
behaviour of which is outside the scope of the present document
might not indicates a likelihood that something will not happen as a result of action taken by some agency
the behaviour of which is outside the scope of the present document

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.
