A method transmits data from a user equipment (UE) including a transceiver having a set of available antennas. The method selects a subset of antennas from the set of available antennas; and transmits the data by the transceiver using the subset of antennas. The selecting subset of antennas includes transmitting sounding reference signals (SRSs) according to specified times, frequencies, and antennas; and receiving, in response to the transmitting the SRSs, information indicative of a selection of the subset of antennas.
