A method for communicating a plurality of data streams between a transmitting device with multiple transmit antennas and a receiving device, is disclosed. The method comprises determining a set of power weightings, efficiently quantizing the power weightings, and providing the set of power weightings the transmitting device. Another aspect of the invention comprises the transmitter implicitly signaling the number of data streams which the receiver should feedback information forthrough the amount of feedback requested. An additional aspect of the invention is means of determining the best codebook weights by combining the maximum power and maximum capacity criteria. |
