Patent ID: 8228858

Claim:
A method for antenna selection (AS) in a wireless communication network, the network comprising user equipment (UE), wherein the UE comprises a plurality of subsets of antennas including a selected subset of antennas and an unselected subset of antennas, and wherein the UE is configured to transmit only from a subset of antennas at a time, comprising: transmitting user data from the selected subset of antennas within a set of subframes; transmitting a sounding reference signal (SRS) from the unselected subset of antennas within at least one subframe in the set of subframes to enable antenna selection for user data transmission; switching from the selected subset of antennas to the unselected subset of antennas for the transmitting the SRS; and switching back, after the transmitting the SRS, from the unselected subset of antennas to the selected subset of antennas for the transmitting the user data.
