We investigate the application of wireless multicast technology in public safety network (PSN) in future wireless communication\nsystem. The hybrid unicast/multicast transmission system is proposed and analyzed in 3D massive multi-input multi output\n(MIMO) channel.The mutual coupling channel model is adopted under the different antenna array configuration scenarios. The\nproposed hybrid system adopts multicast beamforming in the multicast groups as well as multiuser-MIMO (MU-MIMO) linear\nprecoding in the unicast group to increase system throughput. The null space method based interference cancellation is further\nperformed between each group to eliminate signal leakage generated from each group. Comparisons between two types of antenna\narray configurations, different channel models, linear precoding as well as multicast beamforming, and user grouping strategies for\nmulticast services are presented and analyzed by simulation.
