Wireless networks incorporating implicit antenna selection based on received sounding reference signals
First Claim
1. 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, andtransmitting data from the transceiver to the base station using the selected subset of antennas.

Abstract
A method and system selects antennas in a wireless network including a base station and user equipment (UE) transceivers. The base station specifies times and frequencies to transmit sounding reference signals (SRSs), and antennas to use to transmit the SRSs for the specified times and frequencies. The transceivers transmit the SRS according to the specified times, frequencies, and antennas. The stopping and starting of the SRS are specified implicitly. The base station selects subsets of the set of available sets of antennas, and indicates the selected subset of antennas to the transceiver.
