Abstract:
1. A method of providing channel state information feedback in a wireless communication system, the method comprising: measuring an original channel state information comprising an original Channel Quality Indicator (CQI) for each of a plurality of channels; applying an offset vector to the original channel state information to generate modified channel state information, the offset vector comprising a plurality of offset values, each offset value corresponding to one of the original CQIs, the modified channel state information comprising information associated with the original CQI for each of the plurality of channels; identifying, by a subscriber station, a subset of the channels based on the modified channel state information; reporting one of the original channel state information and the modified channel state information for the identified subset of the channels; and adjusting the plurality of offset values of the offset vector based on a load on each of the plurality of channels so as to redistribute the load on each channel in order to balance an overall system load such that no channel is overloaded or underutilized, wherein the load on each of the plurality of channels is monitored by a base station serving the subscriber station.
