OFDMA subchannel allocation has been wellstudied.

However, most of the available literature considers a

single cell system without cochannel interference. We present a

novel intercell interference avoidance scheme, in which the

downlink OFDMA subchannels are allocated through intercell

coordination in a multicell environment. The proposed scheme not

only aims to achieve maximized network throughput but also

focuses on providing improved throughput for cell or sector edge

users that are most affected by intercell interference
