“…In [46], the authors employed the Lyapunov optimization theory to decompose the dynamic communication mode selection problem and provide a lower bound of the system throughput and proposed an algorithm to achieve approximate maximization. In [47], the joint relay selection and resource allocation problem were solved in a multi-user, multi-carrier and multi-cellular network, thus increasing the throughput of users in the cell-edge. As the co-channel interference exists in the underlying mode of the D2D communication network, the resource allocation problem must be solved under the interference constrains to guarantee the quality of communications [48,49].…”

Device-to-device (D2D) cooperative relay can improve network coverage and throughput by assisting users with inferior channel conditions to implement multi-hop transmissions. Due to the limited battery capacity of handheld equipment, energy efficiency is an important issue to be optimized. Considering the two-hop D2D relay communication scenario, this paper focuses on how to maximize the energy efficiency while guaranteeing the quality of service (QoS) requirements of both cellular and D2D links by jointly optimizing relay selection, spectrum allocation and power control. Since the four-dimensional matching involved in the joint optimization problem is NP-hard, a pricing-based two-stage matching algorithm is proposed to reduce dimensionality and provide a tractable solution. In the first stage, the spectrum resources reused by relay-to-receiver links are determined by a two-dimensional matching. Then, a three-dimensional matching is conducted to match users, relays and the spectrum resources reused by transmitter-to-relay links. In the process of preference establishment of the second stage, the optimal transmit power is solved to guarantee that the D2D link has the maximized energy efficiency. Simulation results show that the proposed algorithm not only has a good performance on energy efficiency, but also enhances the average number of served users compared to the case without any relay.

In the next-generation wireless networks, cooperative communication is one of the auspicious techniques through which spatial diversity could be achieved by permitting the single antenna to act as virtual multiple input multiple output (VMIMO). The fundamental principle of cooperative communication was established on different types of relaying protocols and implementation of different relaying protocols according to the requirements of communication scenarios. The challenging task for achieving a high performance in cooperative communication is to find out the optimal relay node (RN) among different prevailing RNs. The basic purpose of cooperative communication is to maximize the performance of the network and minimize the overhead triggered by RNs by considering different communication metrics, i.e., signal to noise ratio (SNR), channel state information (CSI), and bit error rate (BER). This study presents a review of different cooperative relaying protocols with best relay selection techniques in the next-generation wireless network. Moreover, the different challenges faced by millimeter wave in 5G wireless networks and the role of cooperative communication to overcome those challenges are discussed. Turkey is that it transmits the duplicates of a signal to the destination independently. Many ideas regarding cooperative communication were first derived by Nichola et al. [5]. In the next-generation wireless network, cooperative communication may be one of the promising approaches for achieving the high data rates as well as efficient utilization of the bandwidth. Cooperative communication uses a RN, to provide coverage in the holes within the Long-Term Evolution-Advanced (LTE-A) cellular networks [6]. Similarly, in mm-wave communication that is considered in 5G, the relaying techniques are used to overcome different challenges of link blockage, backhaul connectivity, and path loss etc. Moreover, to make this technology more efficient and reliable, further improvements are required to achieve these goals.This study presents a broad overview of different relaying protocols with optimal relay selection methods used in different wireless networks. In addition, this study presents the potential benefits of using cooperative communication to overcome different challenges faced by the next generation of wireless networks. The remainder of this article is organized as follows. Section 2 presents existing research on cooperative communication. Section 3 gives an overview of cooperative communication, in which different relaying protocols are presented and comparison between them. In Section 4, we discuss the review of optimal relay selection techniques. In Section 5, we explain the different challenges faced by mm-wave and how to overcome them by cooperative communication. Section 6 summarizes the future challenges in cooperative communication and finally the conclusion is given in Section 7. Sami et al. [7] demonstrate a survey and taxonomy on medium access control for cooperative communication. This study classifies ...

“…Besides, we assume that D2D transmissions occupy the uplink channel and the channel state information (CSI) G SB and G RB are perfectly known at the DUE transmitter and the relay respectively in order to implement power control 5 . As a result, all interference can be classified into three categorizes, which are the interference from the CUE to the DUE receiver and the relay, the interference from the DUE and the relay to the BS and the residual SI due to adopting full-duplex forwarding protocol.…”

“…As observed in (4), the random instantaneous channel gain G RB is a common term in both equations and thus will result in correlation when analyzing the minimum function in (5). To temporarily eliminate this correlative effect, we condition on P R = p, so that we can first analyze the outage probability at the first and second hop P {Γ SR < s|p} and P {Γ RD < s|p}, independently, and thus analyze the distribution of the minimum function in (5). Now, let us take a close look at the denominator of Γ SR as given in (4).…”

This paper proposes a full-duplex cooperative device-to-device (D2D) communication system, where the relay employed can receive and transmit signals simultaneously. We adopt such a system to assist with D2D transmission. We first derive the conditional cumulative distribution function (CDF) and the probability density function (PDF) of a series of channel parameters when the interference to the base station (BS) is taken into consideration and power control is applied at the D2D transmitter and the relay node. Then, we obtain an exact expression for the outage probability as an integral and also a closed-form expression for a special case, which can be used as a good approximation to the general case when residual selfinterference (SI) is small. Additionally, we also investigate the power allocation problem between the source and the relay and formulate a sub-optimal allocation problem, which we prove to be quasi-concave. Our analysis is verified by Monte Carlo simulations and a number of important features of full-duplex cooperative D2D communications can be thereby revealed. Index Terms-Cooperative device-to-device (D2D) communications, full-duplex system, outage performance, power allocation. I. INTRODUCTION Underlay device-to-device (D2D) communication coexisting with traditional cellular communication has been a frequent topic of research in both academia and industry for years, because of its high power efficiency, high spectral efficiency and low transmission delay [1]-[3]. Meanwhile, cooperative communication has also gained interest, since it can effectively enhance network reliability and performance [4]. Recently, researchers have tried to combine the merits of both communication systems and have proposed the concept of cooperative D2D communication [5]. However, most recent works only treat the combination of D2D communication with half-duplex relays, which will degrade the system throughput by a fraction due to the use of multiple orthogonal time or frequency slots for one complete transmission. On the other hand, full-duplex relaying is capable of overcoming this shortcoming, but at the cost of producing residual self-interference (SI) [6]. A simplified full-duplex D2D network model is proposed in [7]. The effects of residual SI are analyzed and a numerical optimization of the total transmit power in this full-duplex D2D network model is carried out without presenting analytical results in [8]. Power allocation problems in full-duplex D2D
