Research on Grouping Methods in CoMP Networks

Abstract

Coordinated multi-point (CoMP) networks are inter-cell cooperation mechanisms specifically proposed to enhance transmission of users at cell edge. Therefore, selection appropriate group of cells to provide better transmission service is an important research topic in CoMP networks. In this paper, we proposed two grouping methods in CoMP networks including: (1) the arriving user accesses the same empty channels of his best and second best link quality cells and (2) if there are no same empty channels from his best and second best link quality cells, allow the arriving user to access one of the empty channels from his best or second best link quality cells. Simulation Results show that the proposed model can effectively evaluate influences of system performance of these two grouping methods.
