Patent ID: 7796717

Claim:
A method for modifying a signal according to a diversity parameter adjustment, comprising: modifying a signal according to a current diversity parameter adjustment to produce a first and a second current transmit signals, the first and the second current signals respectively transmitted from first and second antennas of a modifying communication device to a feedback communication device; receiving a feedback signal reflecting feedback information describing the first and the second current signals combined as received by the feedback communication device, the feedback signal comprising a plurality of frames, a frame comprising a plurality of slots, a slot having a slot power value; establishing slot timing of the plurality of slots; establishing frame timing of the plurality of frames from the plurality of slot power values, wherein establishing the frame timing of the plurality of frames from the plurality of slot power values comprises: identifying one or more unavailable slots from the plurality of slot power values; and establishing the frame timing of the plurality of frames in accordance with the one or more unavailable slots; and modifying the signal according to a next diversity parameter adjustment in accordance with the frame timing to thereby produce first and second next transmit signals, the next signals respectively transmitted from said first and second antennas of said modifying communication device.
