Multicell Downlink OFDM Subchannel Allocations Using Dynamic Intercell Coordination
In this paper, we present a novel integer programming (IP) optimization formulation for downlink OFDM subchannel allocations in a multicell system and propose viable sub-optimal solutions. The schemes use dynamic intercell coordination in order to avoid or minimize dominant co-channel interference and achieve maximum network throughput by exploiting multicell multiuser diversity and interference avoidance gains. The performance of the proposed schemes is compared with that of reference round-robin schedulers without intercell coordination. It is observed from snapshot simulation results that the proposed schemes outperform the reference schemes in terms of throughput and quality of service (QoS) considerations.
