Inband Full-Duplex D2D Communications Underlaying Uplink Networks with Mutual SIC NOMA

Abstract : This paper studies the combination of full-duplex (FD) and half-duplex (HD) device-to-device (D2D) communications while underlaying a cellular system. Non-orthogonal multiple access (NOMA) is used to manage the interference between devices and cellular users using mutual successive interference cancellation (SIC) and to boost the performance of D2D underlay systems, which are mainly interference-limited. For this purpose, we derive the conditions allowing for the application of mutual SIC in FD-D2D and HD-D2D systems. We compare the performance of the proposed strategy against state-of-the-art, where SIC is not applied between D2D devices and cellular users. The results show that important gains can be achieved by using NOMA in this context and highlight the importance of self-interference (SI) cancellation factors for determining the best transmission mode. Index Terms-Non-orthogonal multiple access, D2D, mutual SIC, full duplex, half duplex, residual self interference.
