1 Scope p. 7

The present document specifies details of conformance testing of UE Multiple Input Multiple Output (MIMO) Over-the-Air (OTA) requirements and test methodologies for FR1 (NR SA and NSA). The correspondent testing methodologies are also presented in the Annex A of the present document.

2 References p. 7

The following documents contain provisions which, through reference in this text, constitute provisions of the present document.

References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific.
For a specific reference, subsequent revisions do not apply.
For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest version of that document in the same Release as the present document.

3 Definitions of terms, symbols, and abbreviations p. 7

3.1 Terms p. 7

For the purposes of the present document, the terms given in TR 21.905 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905.

Free Space (FS):

UE used in a free space configuration

Handheld UE:

UE intended to be used in hand held scenario

primary mechanical mode:

mode that is most often used for a specific user scenario.

PAS Similarity Percentage (PSP):

similarity of the PAS produced by the OTA system and the reference PAS. PSP is defined as (1-TVD) * 100 %. PSP=100 % denotes full similarity and PSP = 0 % denotes full dissimilarity.

3.2 Symbols p. 8

For the purposes of the present document, the following symbols apply:

P_RS-EPRE-MAX

Maximum downlink RS-EPRE
