The UEs at the edge of the cell in TD-LTE-Advanced system suffer from a poor communication quality invariably. In this paper, a novel relay mechanism, called Device-to-Device mobile relay (D2DMR), is proposed. In the D2DMR mechanism, the UE at the edge of the cell or in a poor coverage area can communicate with eNodeB via another UE’s relay. The link between these two UEs is established in the Device-to-Device (D2D) communication mode. The D2DMR mechanism can expand the cell coverage and improve the system capacity of TD-LTE-Advanced system with little interference. Numerical analysis and simulation results show that the D2DMR mechanism can improve the throughput of the TD-LTE-Advanced system greatly. |
