Dynamic Clustering for Multicell Cooperative Processing in Mobile Communications
Multicell cooperative processing (MCP) has been recognized as a promising technique for enhancing the spectral efficiency of future wireless systems.However,MCP inevitably requires increased radio feedback and backhaul overhead.Therefore,only a limited number of base stations can cooperate for an affordable system complexity in practice.In this paper,we propose a novel dynamic clustering scheme for the cellular system incorporating MCP.The clusters are formed dynamically from users point of view to minimize the co-channel interference,and are allowed to be overlapped.The objective of the clustering scheme is rate maximization of the cell-edge users.Compared with some conventional cooperation clustering schemes,the proposed scheme has proven to provide a good trade-off between user rates and overhead.Simulation results show that the user rates of the proposed scheme with a cluster consisting of two sectors can reach up to 95% of its upper bound.
