Optimal Resource Allocation in Multicast Device-to-Device Communications Underlaying LTE Networks
Optimal Resource Allocation in Multicast Device-to-Device Communications Underlaying LTE Networks
In this paper, we present a framework for resource allocations for multicast device-to-device (D2D) communications underlaying a cellular network.The objective is to maximize the sum throughput of active cellular users (CUs) and feasible D2D groups in a cell, while meeting a certain signal-to-interferenceplus-noise ratio (SINR) constraint for both the CUs …
