Method and system for generating antenna selection signals in wireless networks
First Claim
1. A method for joint resource blocks assignment and antenna selection (AS) in a wireless communication network, the network comprising user equipment (UE), wherein the UE comprises a plurality of subsets of antennas, the UE is configured to transmit a sounding reference signal (SRS) from a subset of antennas at a time, comprising:
- transmitting a first SRS from a first subset of antennas;
transmitting a second SRS from a second subset of antennas;
receiving, in response to the transmitting of the first SRS and the second SRS, information related to an optimal subset of antennas determined based on estimation of channels for the first subset of antennas and for the second subset of antennas based on the first SRS and the second SRS;
receiving, in response to the transmitting the first SRS and the second SRS, information related to an optimal subset of resource blocks; and
transmitting a data symbol from the optimal subset of antennas using the optimal resource block.

Abstract
Embodiments of the invention describe a method for joint resource blocks assignment and antenna selection (AS) in a wireless communication network, the network comprising user equipment (UE), wherein the UE comprises a plurality of subsets of antennas, the UE is configured to transmit a sounding reference signal (SRS) from a subset of antennas at a time. The method transmits a first SRS from a first subset of antennas and a second SRS from a second subset of antennas. Upon receiving, in response to the transmitting of the first SRS and the second SRS, information related to an optimal subset of antennas, and information related to an optimal subset of resource blocks, the method transmits a data symbol from the optimal subset of antennas using the optimal resource block.
