The method defined in claim 8 wherein the additional information comprises traffic load information on each cluster of subcarriers.

The method defined in claim 1 wherein the indication of subcarriers is received via a downlink control channel.

The apparatus defined in claim 18 wherein the indication of subcarriers is received via a downlink control channel between the base station and the at least one subscriber unit.

The method defined in claim 8 wherein the indication of coding and modulation rates comprises an SINR index indicative of a coding and modulation rate.

An apparatus comprising: a plurality of subscribers in a first cell to generate feedback information indicating clusters of subcarriers desired for use by the plurality of subscribers; and a first base station in the first cell, in response to receiving inter-cell interference information, coordinates with other cells to make a cluster assignment decision, the first base station performing subcarrier allocation for OFDMA to allocate OFDMA subcarriers in clusters to the plurality of subscribers based on inter-cell interference avoidance and intra-cell traffic load balancing in response to the feedback information. view more
