6.1 General
25.1423GPPBase Station (BS) conformance testing (TDD)Release 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 or MIMO transmission, the requirements apply for each transmitter antenna connector.
A BS supporting MC-HSDPA transmits multiple carriers simultaneously on adjacent carrier frequencies.
Unless otherwise stated, all measurements shall be made 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, the tests according to subclauses 5.14.4 shall be performed to ensure that the requirements are met at test port B.
