Abstract:
1. 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 first subset of antennas and a second subset of antennas, and wherein the UE is configured to transmit a sounding reference signal (SRS) from a subset of antennas at a time without transmitting user data, comprising: transmitting a first SRS from the first subset of antennas in a first subframe, wherein the first subframe does not include the user data; transmitting a second SRS from the second subset of antennas in a second subframe, wherein the second subframe does not include the user data, wherein the first SRS and the second SRS are broadband SRS; receiving, in response to the transmitting the first SRS and the second SRS, information identifying an optimal subset of antennas from the first subset of antennas and the second subset of antennas; and selecting the optimal set of antennas such that the optimal subset of antennas is selected without transmitting the user data.
