Patent ID: 7844300

Claim:
A method for controlling a transfer of signals by a first communication device to a second communication device through a wireless network, the second communication device having at least N antennas where N is equal to or greater than two, the first communication device having at least M k antennas where M k is equal to or greater than two, the method comprising: determining a weighting vector v k , where k is an indicia representative of the first communication device, the weighting vector v k being composed of M k elements, each element of the weighting vector v k being expected to weight the signals transferred by the first communication device through an antenna of the first communication device; determining, with the second communication device, a second weighting vector w k , based on √{square root over (P r )}H T V k , P r being a power of a signal transferred by the first communication device to the second communication device, H T being a transpose of a channel response matrix H; and transferring to the first communication device through the wireless network at least a signal comprising or being weighted by the second weighting vector w k .
