Abstract:

Device-to-Device (D2D) communication is a promising way to improve spectral, energy and latency performance in future wireless networks. This paper focuses on the network-controlled approach considering that overlay D2D communications are enabled in a multi-cell system, where legacy users coexist with potential D2D pairs. Two of the most critical problems in the D2D concept, mode selection and user scheduling are jointly addressed. In particular, aiming at maximizing the total system uplink throughput, we present the joint optimization mode selection and scheduling problem in a multi-cell environment with intra-cell and cross-cell D2D communications enabled. Due to the non-linear and non-convex form of the initial problem, we employ a linearization method reformulating it as a 0-1 integer program. In a multi-cell environment, the interference and densification significantly affect the D2D communication gain, as well as the cross-cell D2D concept, which is usual ignored. System-level simulations are executed to evaluate the performance of the proposed scheme and examine the trends of total D2D communication benefit, consisting of direct and offloading gain, for various system parameters.
