The present document specifies the Radio Frequency (RF) test methods and conformance requirements for NR and NB-IoT operation in NR in-band Base Station (BS) Type 1-C and Type 1-H. These have been derived from, and are consistent with the conducted requirements for BS Type 1-C and BS Type 1-H in NR BS specification defined in TS 38.104.
A BS type 1-C only has conducted requirements so it requires compliance to this specification only.
A BS type 1-H has both conducted and radiated requirements so it requires compliance to the applicable requirements of this specification and TS 38.141-2.
BS type 1-O and BS type 2-O have only radiated requirements so they require compliance to TS 38.141-2 only.
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.
