“…In the literature, an important mechanism in the future network is the Coordinated Multi-Point (CoMP) , which has two categories. One is Coordinated Scheduling/Coordinated Beamforming (CS/CB) [ 7 , 8 , 9 ], where the data destined to a user is saved only in its serving cell and the scheduling of resources and beamforming are co-determined by the cooperating set. The other is Joint Processing (JP) , where the data destined to a user is saved in each cell of the cooperating set and the resource scheduling is co-determined by the cooperating set.…”

Coordinated Multi-Point (CoMP) is an important technique in B4G/5G networks. With CoMP, multiple base stations can be clustered to compose a cooperating set to improve system throughput, especially for the users in cell edges. Existed studies have discussed how to mitigate overloading scenarios and enhance system throughput with CoMP statically. However, static cooperation fixes the set size and neglects the fast-changing of B4G/5G networks. Thus, this paper provides a full study of off-peak hours and overloading scenarios. During off-peak hours, we propose to reduce BSs’ transmission power and use the free radio resource to save energy while guaranteeing users’ QoS. In addition, if large-scale activities happen with crowds gathering or in peak hours, we dynamically compose the cooperating set based on instant traffic requests to adjust base stations’ BSs’ transmission power; thus, the system will efficiently offload the traffic to the member cells which have available radio resources in the cooperating set. Experimental results show that the proposed schemes enhance system throughput, radio resource utilization, and energy efficiency, compared to other existing schemes.
