Abstract: In a TD-SCDMA user equipment (UE) with multiple receive chains, receive diversity may be implemented where multiple receive chains may simultaneously activate to receive downlink signals. Receive diversity may be enabled when single chain reception provides undesired results and when receive diversity will not impact power consumption too much. A state machine controls receive diversity operation based on operating conditions such as control channel activity, successful control channel decoding, signal-to-interference ratio, and other factors.
