Dynamic Association for Load Balancing and Interference Avoidance in Multi-Cell Networks
Overview Next-generation cellular networks will provide higher cell capacity by adopting advanced physical layer techniques and broader bandwidth. Even in such a next-generation system, boundary users would suffer from low throughput due to severe Inter-Cell Interference (ICI) and unbalanced user distributions among cells, unless additional schemes to mitigate this problem are employed. This paper tackles this problem by jointly optimizing Partial Frequency Reuse (PFR) and load-balancing schemes in a multi-cell network. It formulates this problem as a network-wide utility maximization problem and proposes optimal offline and efficient online algorithms to solve this. This online algorithm turns out to be a simple mixture of inter- and intra-cell handover mechanisms for existing users and admission control and cell-site selection mechanisms for newly arriving users.
