6.1 General
37.1043GPPMulti-Standard Radio (MSR) Base Station (BS) radio transmission and receptionNR, E-UTRA, UTRA and GSM/EDGERelease 17TS
Unless otherwise stated, the requirements in clause 6 are expressed for a single transmitter antenna connector. In case of multi-carrier transmission with multiple transmitter antenna connectors, transmit diversity, DB-DC-HSDPA or MIMO transmission, the requirements apply for each transmitter antenna connector.
A BS supporting DC-HSDPA and DB-DC-HSDPA transmits two UTRA FDD cells simultaneously. A BS supporting DC-HSDPA transmits two UTRA FDD cells simultaneously on adjacent carrier frequencies.
Unless otherwise stated, the transmitter characteristics are specified at the BS antenna connector (test port A) with a full complement of transceivers for the configuration in normal operating conditions. If any external apparatus such as a TX amplifier, a filter or the combination of such devices is used, requirements apply at the far end antenna connector (test port B).
Unless otherwise stated the requirements in subclause 6 applies at all times, i.e. during the Transmitter ON period, the Transmitter OFF period and the Transmitter transient period.

Values for Foffset, RAT to meet transmitter requirements are specific for each RAT in each Band Category as specified in subclause 4.5.1 for Band Category 1, subclause 4.5.2 for Band Category 2 and subclause 4.5.3 for Band Category 3.
Unless otherwise stated the requirements for NB-IoT in subclause 6 applies for all operation modes (In-band operation, Guard-band operation and Stand-alone operation).
