Maximum proportional fairness of full duplex cooperative NOMA with SWIPT communication in millimeter wave networks

Abstract

In this paper, we investigate a power allocation problem for cooperative communication with non-orthogonal multiple access and simultaneous wireless information and power transmission (C-NOMA-SWIPT) in the millimeter wave networks. There are two users (near user and edge user) in each cooperative communication network. The near user receives the information and power from the base station (BS) using power splitting in SWIPT network, then decodes and forwards the data to the edge user simultaneously. The edge user receives the information from the BS and the relay near user, then decodes in the maximum rate combining mode. Full duplex relaying mode with millimeter wave network are jointly explored. With the purpose of the fairness and maximum sum data rate consideration, we formulate the power allocation problem as a non-convex programing problem (NP-hard). We propose a low-complexity two steps solution to solve the problem in polynomial time. The simulation results indicated that the fairness and sum data rates of users of our strategy are much better than those of the conventional NOMA and OMA strategies.
