Cell Selection Algorithm Based on Coordinated Beamforming

Abstract:

In LTE-A (LTE-Advanced) system, CoMP (Coordinated Multipoint Transmission) is used to improve system capacity and cell coverage. CB(Coordinated Beamforming), as a way of CoMP, using multi-cell coordination to improve the spectrum efficiency of edge users. Therefore, coordinated cell selection is important. To achieve better performance, multiple factors rather than a single one are considered in cell selection, channel gain as well as cell load is taken into account in the article. Multiple factors constitute a matrix to find the optimal coordinated cells, multi-objective optimization is used here. Simulation result shows system performance of the proposed algorithm is better than the one only considers channel gain.
