Foreword

This Technical Specification has been produced by the 3 Generation Partnership Project (3GPP).

The contents of the present document are subject to continuing work within the TSG and may change following formal

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:
Version x.y.z
where:
x the first digit:
1 presented to TSG for information;
2 presented to TSG for approval;
3 or greater indicates TSG approved document under change control.

y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections,

updates, etc.

z the third digit is incremented when editorial only changes have been incorporated in the document.

1 Scope

The present document specifies radiated test methods and conformance requirements for single RAT E-UTRA operation,

single RAT UTRA operation (FDD and TDD) and Multi-Standard Radio (MSR) UTRA and E-UTRA Active Antenna

System (AAS) Base Station (BS). These have been derived from, and are consistent with non-AAS BS specifications in

3GPP TS 25.104 [2], 3GPP TS 25.105 [3], 3GPP TS 36.104 [4] or 3GPP TS 37.104 [5]. The technical specification

3GPP TS 37.145 is in 2 parts, part 3GPP TS 37.145-1 [9] covers conducted requirements and part 3GPP TS 37.145-2

(the present document) covers radiated requirements.

The present document does not establish radiated test methods and conformance requirements for Band 46 operation as

it is not supported by AAS BS. Conducted Band 46 test requirements are still applicable for AAS BS for protection of

and against Band 46 operation, as specified in 3GPP TS 37.145-1 [9].
