Abstract:
A method selects antennas in a wireless network including a base station and one or more transceivers. The base station specifies times, subcarriers and subsets of antennas to use to transmit sounding reference signals (SRS) to the base station. Then, the transceiver transmits the SRS according to the specified times and subcarriers using different subsets of the set antennas. The SRS are received in the base station, and the base station selects one of the different subset of the antennas based on the received SRS, and indicates the selected subset of the antennas to the transceiver.
