… Abstract—This paper addresses the joint spectrum sharing and power allocation problem
for device-to-device (D2D) communications underlaying a cellular network (CN). In the context …

… with multiple D2D receivers simultaneously … D2D groups and power allocation in each D2D
group. • For the subchannel assignment, we first give the fixed power allocation in each D2D …

… conducted on D2D power allocation, … D2D power allocation with SWIPT power-splitting
architecture, and address it by establishing a novel game-theoretic model. Two power allocation …

… SYSTEM MODEL We consider D2D communication as an underlay coexistence with … It
is assumed that D2D communications utilize the uplink spectrum of cellular networks with …

… Then, we perform power allocation for a single D2D link and its reuse partner, assuming
fixed subcarrier assignment. Finally, we present the complete EHGRA algorithm based on two …

… new D2D communication scheme that allows D2D links to underlay cellular downlink by
assigning D2D … The system objective is to optimize the achievable rates for the D2D users while …

… ratio and the transmit power constraints. Then, we develop an optimal power allocation
algorithm to maximize the minimum transmission rate of the scheduled D2D links. Numerical …

… , reducing the power consumption, and increasing the instantaneous data rate. In this paper,
we propose a distributed power allocation scheme for D2D OFDMA communications and, in …
