Abstract

In this paper, a distributed algorithm for dynamic frequency reuse scheme in OFDMA downlink cellular networks is proposed. Each cell is divided into two regions, namely, inner and outer regions. The proposed distributed algorithm is based on minimizing the total interference at all users in each region. Unlike other fractional frequency reuse (FFR) schemes, the main advantage of the proposed algorithm is that it adapts to the network channel conditions. Simulation results show that the proposed algorithm provides better performance than that of FFR, in terms of both total system throughput and average user bit-rate.
