Patent ID: 8094625

Claim:
A method implemented in an apparatus for communicating data in a wireless communication system, the method comprising: receiving, by a processor at a transmitter, information indicative of a performance of a first communication channel assigned to a first receiver, wherein the first communication channel comprises at least a first subchannel and a second subchannel, each subchannel having a designated respective frequency; adjusting, by a controller at the transmitter, based at least in part on the received performance information, an initial power level designated for the first subchannel of the first communication channel to a first power level, and adjusting an initial power level designated for the second subchannel of the first communication channel to a second power level, wherein the first power level and second power level achieve approximately equal signal-to-noise ratios (SNRs) for the first subchannel of the first communication channel and the second subchannel of the first communication channel at the first receiver and each of the SNRs resulting in part from different spatial signatures; and transmitting, by the processor at the transmitter; data over the first and second subchannels to the first receiver at the first and second power levels, respectively.
