摘要： A method and system for improving closed loop feedback in transmit diversity communication. In one embodiment of the invention, a predetermined variation of one or more transmit diversity parameters is performed at the transmit diversity transmitter. The receiver compares the transmit diversity parameter values of the received signals to the predetermined variation and transmits to the transmitter a value of a transmit diversity correction parameter. The transmitter may use this correction value to modify the transmit diversity parameter in a subsequent transmission.

摘要： A signal is modified according to a current diversity parameter adjustment, and is transmitted from a modifying communication device to a feedback communication device. A feedback signal reflecting feedback information describing the signal as received by the feedback communication device is received. The feedback signal comprises frames, and a frame comprises slots, where a slot has a slot power value. The frame timing of the frames is established from the slot power values. The signal is modified according to a next diversity parameter adjustment in accordance with the frame timing.
