1  ScopeWord‑p. 17

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.
