Power allocation for device-to-device communication underlaying massive MIMO multicasting networks

Abstract

Device-to-device communication (D2D) is an emerging technology aiming at enhancing the performance of next generation wireless communication systems. D2D communication enables two mobile stations to communicate directly without traversing the Base Station (BS). Smart techniques should be applied to manage the interference between the BS and the D2D communicating devices. In this paper, we investigate the problem of BS precoder design and Power Allocation (PA) to deploy D2D communication in a single-cell network. We assume that the BS uses a very large number of antennas, referred to as Massive Multiple-Input-Multiple-Output (MIMO). We propose solution algorithms to maximize the sum of the achievable data rates of the D2D pairs, or their minimum, while maintaining some Quality of Service (QoS) constraints on the Cellular User Equipments (CUEs) which communicate with the BS. Simulation results show that the proposed solutions are superior to the conventional power allocation schemes.
