Abstract
Millimeter-wave network based on beamforming is an interference-limited network. In order to mitigate the interference for the 5G millimeter-wave cellular network, the concept of cooperative multi-beam transmission (Beam-CoMP) is proposed in this paper to improve cell capacity. For users in the beam overlapping zone, there is strong interference between beams, so for such users, overlapping beams provide services to users through cooperation. This method can solve the problems of poor edge coverage and serious interference of overlapping coverage of beams at the same time. The specific process of beam cooperation is given and the Beam-CoMP method proposed is simulated to verify its effectiveness in improving the UE performance. The results show that cell capacity increases with the increase of the number of users in the service beam.
