Spectral Efficiency Maximization for D2D Communications Underlaying a Cellular System

초록

This paper considers device-to-device (D2D) communications underlaying an uplink cellular network that adopts sparse code multiple access technology. We aim to maximize the spectral efficiency for D2D links in a transmission block via a joint power and resource allocation subject to the quality-of-service requirements for both cellular user equipments and D2Ds. We propose a low-complexity two-phase algorithm based on heuristic search and inner approximation method to efficiently solve the problem. © 2018 IEEE.
