Abstract
Device-to-Device (D2D) links in cellular networks are expected to satisfy the increasing the local data traffic demands. This technique aims to admit more users into the network, providing spectral gains over traditional cellular communication. In this paper, we study a latency-aware resource allocation problem in which cellular devices in proximity communicate with each other directly. We consider the D2D link to underlay the cellular uplink where one cellular user and a group of D2D candidate users exist. Based on the channel state and the latency constraint, one of the D2D users are chosen to share the channel with the cellular user in non-orthogonal multiple access (NOMA) fashion. We formulate the problem as a mixed integer non-linear programming, where the sum data rate is maximized subject to the interference and latency restrictions, and evaluate the performance in terms of latency and throughput for different implementation strategies.
