Abstract

In this paper, cooperative non-orthogonal multiple access (NOMA) network

is investigated to aid device-to-device (D2D) communication. In such D2D

NOMA, Amplify and Forward (AF) and Decode and Forward (DF) mode are

deployed to signal processing at relay who intends to serve NOMA far user.

To ensure the quality of service (QoS) for the NOMA devices, a minimum rate

requirement is pre-defined for each device. Two main schemes are considered

insightfully: i) The first scenario is that the first device intends to commu￾nicate with the second device through the assistance of AF/DF-assisted base

station (BS), where equips individual power; and ii) The second scenario is that

the wireless powered device is able to communicate with non-energy harvesting

device. Because of the QoS requirement, it is first necessary to determine per￾formance gap in two folds: relay and direct mode; non-wireless power transfer

(NWPT) scenario and wireless power transfer (WPT) scenario, by comparing

the outage performance with the required power for satisfying the QoS of the

devices. To further evaluation, we extend our analysis on non-linear energy har￾vesting policy and multiple NOMA far users which are deployed in such D2D

transmission. If feasible, a closed-form solution is provided for system perfor-

of the proposed D2D transmission strategies.

1 1. INTRODUCTION

2 To fill disadvantages of the fourth generation (4G) systems, many antici￾3 pated functionalities such as internet of things (IoT) and cloud based applica￾4 tions require higher data rates to adapt QoS constraint in the fifth generation

5 (5G) communication systems [1]. Much research effort has been carried out to

6 study novel schemes to satisfy challenging requirements such as high power effi￾7 ciency, massive connectivity, higher data rates, low latency and higher spectral.

8 This requirement can be satisfied if a variety of new technologies such as new

9 multiple access techniques, multi-antenna techniques (MIMO, Beamforming),

10 full-duplex (FD) communications, novel spectrum and Wireless Power Trans￾11 fer (WPT) methods, and an interesting example as in [2]. In these proposi￾12 tions, Non-Orthogonal Multiple Access (NOMA) has been acknowledged as the

13 prospective multiple access scheme for 5G communication system with several

14 advantages including user fairness, spectral efficiency, massive connectivity, and

15 low latency [3]. Since NOMA is able to process signals simultaneously in the

16 same time, frequency, or code considering power domain, it supports multiple￾17 users. By evaluating the channel conditions, base station in NOMA is able

18 to distinguish users among group. The higher power level provides for users

19 with poor channel conditions (so-called weak users) while lower power services

20 users with better channel conditions (so-called strong users). The superimposed

21 multiple information messages is deployed to help the base station of NOMA

22 to transmit to the anticipated receivers using superposition coding (SC) tech￾23 nique. Each NOMA user first consider stronger users’ messages as a noise, and

24 then using successive interference cancellation to eliminate all weaker users’ in￾25 formation messages in order to decode the own message [4]. In [5], to allocate
