Patent ID: 8433258

Claim:
A system that includes a first terminal, where said first terminal comprises: N antennas, where N is at least one; and wherein the first terminal is responsive to M signals received from M antennas of a second terminal by said N antennas, where M is greater than one, to determine attributes of preferred information transfer to said first terminal from said second terminal, in terms of number of data streams, modulation method, and coding type and rate that said second terminal is to employ in a subsequent frame communication to said first terminal, and to send to said second terminal an instruction that specifies said number of data streams, modulation method, and coding type and rate wherein the first terminal determines an overall measure of goodness in detecting information received from said second terminal, where said measure of goodness is based on overall system throughput over all links, Signal-to-Interference-and-Noise-Ratio (SINR), and minimum mean squared error for at least one link, where a link is a channel from between one antenna of said N antennas of said first terminal and one of said M antennas of said second terminal.
