In downlink CoMP transmission, we consider a UE-centric scheme called SHO (Soft Handover) grouping algorithm, which is basically different from recent cell-centric scheme. It could afford more freedom in UEs and cells grouping for collaboration, and provide significant performance gains. Simulation results are provided to show the considerable gains of the proposed algorithm, which have been scaled to compare with single-cell mode.
