Joint processing in multi-cell coordinated shared relay network

This paper investigates multi-cell coordinated shared relay with joint processing (JP) scheme in interference limited network. In general, multi-cell coordinated shared relay network increases the Signal to Interference-plus-Noise Ratio (SINR) in cell edge users, but resource usage efficiency is decreased by two-phase transmission of relay protocol. We propose JP of cooperating BSs and shared relay station (RS) in the relay transmission phase (second phase) to increase resource usage efficiency, and introduce the SVD precoding with phase correction based on the multi-cell coordinated shared RS network to mitigate other cell JP interference in the cluster. Simulation results show that the proposed scheme leads to network capacity enhancement.
