The receiver spurious emissions power is the power of emissions generated or amplified in a receiver unit that appear at the antenna connector?(for BS type 1-C) or at the TAB connector?(for BS type 1-H). The requirements apply to all BS with separate RX and TX antenna connectors?/ TAB connectors.
NOTE: In this case for FDD operation the test is performed when both TX and RX are ON, with the TX antenna connectors / TAB connectors terminated.
For TDD connectors capable of transmit and receive ensure the transmitter is OFF.

In-channel selectivity (ICS) is a measure of the receiver ability to receive a wanted signal at its assigned resource block locations?at the antenna connector
