Performance Improvement with Intra-site CoMP for C-RAN Networks

Abstract

Cloud Radio Access Network(C-RAN) structure is a new approach, it used Coordinated Multiple Points(CoMP) to enhance frequency utilization and increase throughput for cell-edge users. C-RAN consists of two parts: (1) baseband unit (BBU) for data processing; (2) remote radio head (RRH) for data transmission and reception. In this paper, we propose a new C-RAN network and use the CoMP technique. Through observed its spectral efficiency, Signal-to-Interference and Noise Ratio in CoMP scenarios. Simulation results show that the use of coordinated scheduling in the new C-RAN environment is significantly better than the unused.
