Abstract
A method of transmitting or receiving with constrained feedback information. A transmitter transmits a plurality of transmit signals from at least one transmit antenna. The plurality of transmit signals are based on one or more input signals, one or more power gains, and one or more beamformer matrices. The plurality of transmit signals are received as at least one receive signal, at at least one receive antenna of a receiver. The receiver generates the constrained feedback information and transmits the constrained feedback information back to the at least one transmit antenna. The transmitter selects at least one of the power gains and at least one of the beamformer matrices for a subsequent transmission based on the constrained feedback information.
