Patent ID: 8478190

Claim:
A method in a wireless communication device communicating to a base station, the method comprising: receiving known pilot signals sent from a set of transmission antennas; determining, based on the known pilot signals, a recommended first subset of transmission antennas from which transmissions are not intended for the wireless communication device, and a recommended second subset of transmission antennas from which transmissions are intended for the wireless communication device; determining a recommended transmission power setting of each of the first subset of transmission antennas; and sending information to the base station, the information pertaining to the recommended first and second subsets of transmission antennas and the recommended transmission power setting of each of the first subset of transmission antennas; wherein the information pertaining to the recommended first and second subsets of transmission antennas and the recommended transmission power setting of each of the first subset of transmission antennas is represented as an index to a pre-defined set of transmission configurations, each transmission configuration comprising a particular selection of the first and second subsets of transmission antennas and a definition of the transmission power setting of each of the first subset of antennas; and wherein the wireless communication device determines the recommended first and second subsets of transmission antennas and the recommended transmit power setting of each of the first subset of transmission antennas from a pre-defined set of transmission configurations by comparing rate metrics computed for each transmission configuration of the pre-defined set of transmission configurations.
