Abstract
Methods and apparatus are provided for allowing a transmitter (Tx) to perform antenna selection independently of a receiver (Rx) in a transceiver supporting both transmit diversity and receive diversity. Certain aspects may utilize a cross switch, which may be used in a parallel or cross configuration, to provide for the independent antenna selection, such that the Rx may maintain the ability to operate on the same antenna as the Tx, on another antenna, or on both antennas for enhanced receive diversity. Furthermore, certain aspects may employ additional switching in the baseband domain in an effort to avoid, or at least reduce, switching glitches in the Rx caused by changing the cross switch configuration. In this manner, the Rx need not re-converge upon antenna switching.
