Distributed Multi-Cell Resource Allocation with Price Based ICI Coordination in Downlink OFDMA Networks

摘要

Multi-cell resource allocation under minimum rate request for each user in OFDMA networks is addressed in this paper. Based on La-grange dual decomposition theory, the joint multi-cell resource allocation problem is decomposed and modeled as a limited-cooperative game, and a distributed multi-cell resource allocation algorithm is thus proposed. Analysis and simulation results show that, compared with non-cooperative iterative water-filling algorithm, the proposed algorithm can remarkably reduce the ICI level and improve overall system performances.
