Abstract:
Coordinated multi-point (CoMP) has evolved as a performance-optimizing technique for cellular networks. In this paper, we investigate two different spectrum allocation schemes for CoMP (i.e., shared and dedicated) within the context of Remote Radio Head (RRH)-enabled heterogeneous network (Het- Net) topology. The traditional macrocell-only layout serves as baseline. Using spectral efficiency and average user throughput as system-level performance metrics, our results reveal that CoMP based on shared spectrum outperform the other two. The scheme, therefore, has great potential for optimizing radio resources and boosting the performance of next-generation mobile networks.
