Abstract:
1. A method implemented in a receiver having multiple receive antennas for communicating over a radio channel with a transmitter having multiple transmit antennas, comprising: receiving at the multiple receive antennas a received signal transmitted from the transmitter at which information to be transmitted was divided into multiple subsignals, each subsignal processed separately and transmitted from one of the transmit antennas; decoding subsignals from the received signal; subtracting a contribution of each decoded subsignal from the received signal; calculating a capacity associated with each subsignal; determining link control information based on the capacity calculated for each subsignal to generate a first set of link control information; comparing the first set of link control information with multiple sets of pre-calculated link control information; selecting one of the pre-calculated sets best matching the first set of link control information; and transmitting a feedback signal from the receiver to the transmitter including the selected pre-calculated set of link control information for use by the transmitter in processing future subsignals to be transmitted over the multiple antennas.
