Abstract: This paper proposes a maximum-weight-matching resource allocation algorithm. Under the constraints that guarantee the quality of service requirement of the cellular users, and SNR threshold of D2D user, the proposed algorithm coordinates resource allocation between D2D users and cellular users to maximize system throughput. The simulation result show that the proposed algorithm can improve the system throughput, and under 110 dB of SI cancellation, D2D link throughput of full-duplex mode is nearly twice than half-duplex mode.
