abstract = "This paper studies device-to-device (D2D) group association and channel assignment in uplink multi-cell non-orthogonal multiple-access (NOMA) networks. In particular, the goal is to assign D2D groups to cellular user channels at each base-station, while accounting for the interference caused by pairing users with D2D groups. To that end, a multi-objective signal-to-interference-plus-noise ratio (SINR)-maximizing power allocation solution procedure is proposed to determine the optimal power allocation for each (D2D group, user) pair, while meeting quality-of-service (QoS) requirements. After that, the joint D2D group association and channel assignment problem is modeled as a student-project allocation with preferences over (student, project) pairs matching problem. Then, a polynomial-time complexity stable matching algorithm is proposed to pair D2D groups with users, and associate them with base-stations. Simulation results are presented to evaluate the proposed matching algorithm, and compare it to a joint D2D group association, channel assignment and power allocation (J-GA-CA-PA) scheme. The proposed algorithm is shown to efficiently yield comparable SINR - per user and D2D receiver - to the J-GA-CA-PA scheme, while maintaining QoS requirements.",
