    The concept of full duplex (FD)-assisted relay has been introduced to support the relaying transmission using device-to-device (D2D) communications for enhancing communication reliability. Motivated by the recent advance in heterogeneous network using relaying techniques, we consider the D2D communication provided by dedicated FD relay where forward signal from a base station (BS) to the conventional cellular user and D2D user. We mainly derive the instantaneous rate by taking into account the SNR and power allocation parameters, and propose the transmission mode for D2D link. After deriving the rate of the D2D link, we explore the effects of the network parameters on the instantaneous rate.

    In this paper, the outage possibility of device-to-device (D2D)-communication with non-orthogonal multiple access (NOMA) enabled cellular networks from a common threshold-based perspective is studied. Particularly, this work propose NOMA signal processing scheme of D2D transmission mode with or without help of the base station help a portable user equipment (UE) forwarding superimposed signals in relay and direct mode. A united framework is supplied to inspect the link outage possibility in each pair of D2D users over Rayleigh fading channel.

    This paper analyzes the effect of co-channel interference on device-to-device (D2D) communication using amplified-and-forward technique. This paper considered the outage probability of D2D communication using two-way amplify-and-forward relaying protocol over Rayleigh fading channels. For this purpose, this paper presents closed expressions for the cumulative distribution function (CDF) of the signal-to-noise ratio plus the co-channel noise (SINR), throughput of such network under impact of the co-channel interference. The results of this analysis will be verified by the Monte-Carlo simulation method and simulated on Matlab.

    In this paper, we design a energy harvesting-assisted relay which collects energy from signals radiated by PU (primary user) transmitters, then SU (secondary user) transmitters can be used to forward signal to PU receivers. In this model, transmit power of PU transmitters are divided into two equal part for primary network and secondary network in cognitive radio. This paper will discuss how to evaluate system performance under impacts of energy harvesting coefficients through the outage performance. Such analytical expression can be verified through Monte-Carlo simulation to confirm advantage of the proposed model.

    In this paper, we consider one-way relay with energy harvesting system based on power beacon (PB), in which the relay node harvests transmitted power from the PB station to forward signals to destination. We also analyse the relay network model with amplify-and-forward (AF) protocol for information cooperation and Power Splitting-based Relaying (PSR) protocol for power transfer. In particular, the outage probability and optimal energy harvesting (EH) power splitting fraction of novel scheme in are presented. We obtain analytical closed-form expression of optimal energy harvesting (EH) power splitting fraction to minimize the outage probability of system. Using numerical and analytical simulations, the performances of different cases are presented and discussed.
