Patent ID: 7949069

Claim:
A method of communicating between a mobile communication device having a plurality of antenna elements and a base station via a communication link comprising: receiving a first quality indication signal from the base station; calculating a first complex weighting based on said first quality indication signal; selecting one complex weighting between said first complex weighting and a second complex weighting based at least in part on said first quality indication signal; modifying a pre-transmission signal based at least on the selected complex weighting to produce a plurality of modified pre-transmission signals; associating each of said plurality of modified pre-transmission signals with a respective antenna element of the plurality of antenna elements; sending from said mobile communication device said plurality of modified pre-transmission signals from said respective plurality of antenna elements, thereby forming a combined transmitted signal; and prior to receiving said first quality indication signal from the base station: receiving a second quality indication signal from the base station; calculating said second complex weighting based on said second quality indication signal; and storing said second complex weighting wherein said first quality indication signal is different from said second quality indication signal.
