Under adaptive frequency reuse technique, mobile stations in a cellular
orthogonal frequency division multiple access (OFDMA) system are served
by different radio resource regions with appropriate frequency reuse
patterns to mitigate inter-cell interference and improve system capacity.
In a first novel aspect, the mobile stations measure interference
statistics and obtain interference measurement results. The mobile
stations report the obtained interference measurement results to serving
base stations. The serving base stations determine adaptive frequency
reuse patterns based on the received interference measurement result. In
a second novel aspect, a radio resource control element receives the
interference measurement results, determines frequency reuse patterns and
configures radio resource allocation based on the received interference
measurement results. In a third novel aspect, the base stations obtain
the interference measurement results and schedule the mobile stations to
be served with appropriate radio resource regions.
