Patent ID: 8406200

Claim:
A method of communicating data in a wireless communication system, the method comprising: identifying a first receiver from a plurality of receivers, the first receiver being configured to substantially achieve a first predetermined level of performance, wherein a transmitter is configured to transmit data to the first receiver over a first spatial subchannel of a communication channel using a first frequency subcarrier at a first power level that is sufficient to substantially achieve a first signal-to-noise ratio at the first receiver; identifying a second receiver from the plurality of receivers, the second receiver being configured to substantially achieve a second predetermined level of performance, wherein the transmitter is configured to transmit data to the second receiver over a second spatial subchannel of the communication channel using a second frequency subcarrier at a second power level that is sufficient to substantially achieve a second signal-to-noise ratio at the second receiver, wherein a sum of the first power level and the second power level is less than a predetermined maximum power level, and wherein the first spatial subchannel is spatially compatible with the second spatial subchannel; and scheduling the transmitter to communicate with the first receiver over the first spatial subchannel and to communicate with the second receiver over the second spatial subchannel substantially concurrently, wherein the first frequency subcarrier is the same as the second frequency subcarrier.
