Resource allocation with LBS information for cellular based D2D communication networks

D2D (Device-to-Device) communication is emerging technique to increase resource utilization and spectrum efficiency. However, D2D communication has a problem that the efficiency decreases due to interference is increased. we propose a resource allocation scheme to decrease interference. D2D communication utilizes the location information and SINR (Signal-to-Interference-plus-Noise Ratio). In this case, eNB (eNodeB) know the location of all devices. The proposed scheme ensures performance of the D2D communication when the D2D link share the resources of the cellular network in the uplink. Simulation results show that the proposed scheme has the throughput better than scheme with location information.
