Interference Avoidance Through Dynamic Downlink OFDMA Subchannel Allocation Using Intercell Coordination

OFDMA subchannel allocation has been well-studied. However, most of the available literature considers a single cell system without cochannel interference. The authors 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.
