Patent ID: 8055301

Claim:
A method for selecting antennas in a wireless network including a base station and a plurality of user equipment (UE) transceivers, comprising: specifying, in a base station of a frequency division multiplexing wireless network, times and frequencies when to transmit sounding reference signals (SRSs) by a transceiver of the network, in which the transceiver includes a set of available antennas; enabling and disabling a transmission of the SRSs implicitly; transmitting the SRS by the transceiver according to the specified times, frequencies, and antennas only when the transmission is enabled; selecting a subset of antennas of the set of available antennas in the base station based on the received SRSs; indicating the selected subset of antennas to the transceiver, and wherein a first subset of antennas is selected for even sub-frames, and a second subset of antennas is selected for odd sub-frames, and transmitting data from the transceiver to the base station using the selected subset of antennas.
