OFDMA with adaptive subcarrier-cluster configuration and selective loading

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, 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.

A method comprising:

• the base station allocating a first portion of the subcarriers to establish a data link between the base station and the subscriber;
• and then
• the base station allocating a second portion of the subcarriers to the subscriber to increase communication bandwidth.

A base station comprising:

• means for allocating a first portion of the subcarriers to establish a data link between the base station and the subscriber;
• and
• means for allocating a second portion of the subcarriers to the subscriber to increase communication bandwidth.
