Free registration required

Executive Summary

This paper proposes a novel Load Distribution Aware Soft Frequency Reuse (LDA-SFR) scheme for inter-cell interference mitigation and performance optimization in next generation wireless networks. The authors' proposed scheme aims to provide a solution to effectively achieve inter-cell interference mitigation while maintaining high spectrum efficiency to all users in the cell. The proposed scheme consists of two novel algorithms: edge bandwidth reuse and centre bandwidth compensation. Using the edge bandwidth reuse algorithm, cell-edge users can take advantage of uneven traffic load and user distributions within each cell to expand their resource allocations.
