ABSTRACT:
A method and system selects antennas in a wireless network including a base station and user equipment (UE) transceivers. The base station specifies times and frequencies to transmit sounding reference signals (SRSs), and antennas to use to transmit the SRSs for the specified times and frequencies. The transceivers transmit the SRS according to the specified times, frequencies, and antennas. The base station selects subsets of the set of available sets of antennas, and indicates the selected subset of antennas to the transceiver.
