1. Introduction
The next generation LTE-Advanced (LTE-A) network is expected to adopt technologies that not only improve system performance but also build up foundation for new type of services. Direct communication with short range or Device-to-Device (D2D) communication [1,2] is a candidate to satisfy this requirement and has become one of the study items under investigation in releasing 12 of 3GPP LTE. D2D communication allows devices to transmit data directly without passing it through eNodeB(eNB). D2D communication provides high throughput, reduce power consumption [3], and enables new service opportunities and reliable communication while reducing the Base Station (BS) load. Spectrum sharing is one way of reusing spectrum and has been frequently used to improve the performance of wireless networks [4,5]. D2D communication in LTE shares the licensed radio resource with regular LTE links [6]. It has significant advantages on spectral efficiency and power consumption [7]. Furthermore, it is possible to gain higher spectrum usage by letting the D2D links utilize the spectrum resource of cellular links [8] without causing substantial performance degradation to each other. Such way of communication requires a smart design on radio traffic management [9]. Knowing that the ideas of integrating multi-hop relaying systems into cellular networks is not new [10,11]. The advantages of D2D communications in cellular spectrum have been identified and analyzed only recently [12]. Specifically, it has been found that Single-Hop (SH) D2D communication can increase the spectral and energy efficiency of cellular networks by taking advantage of the proximity, reuse, and hop gains. Another line of research suggests that networkassisted Multi-Hop (MH) communications, including mobile relays and relay assisted D2D communications, can not only enhance the achievable transmission capacity, but also improve the coverage of cellular networks. In this paper, we argue that single-hop D2D technology can be applied to further increase the spectral efficiency and energy if the key D2D radio resource management algorithms [13] are suitably extended to support cellular network assisted multi-hop D2D communications. In this work, we consider multi-hop D2D communication underlaying a 3GPP LTE-A network. For better total performance, D2D links and cellular links share the same radio resource and the management of interference becomes a crucial task. We propose a radio resource allocation for multi-hop D2D links based on interference avoidance approach. The problem is to optimize the transmitting power levels of D2D users in order to maximize the cell throughput while preserving the SINR performance for the cellular user [14]. We introduce the scenario of multi-hop communications, and discuss that how to build multi-hop communication, how D2D Users Equipment (UEs) are distributed, and how to reduce the outage probability in D2D enabled cellular network [15]. In this context, the outage probability is an important metric that can improve the network QoS [7]. As a major contribution, we derive outage probability closed form expressions for the D2D link. Then we study and analyze the outage performance of a multi-hop D2D route. We derive the general closed form expression of outage probability of the multi-hop D2D routes. We discuss that how to build multi-hop communication, how D2D UEs are distributed, and how to reduce the outage probability in D2D-enabled cellular network. We analyze and compare the proposed scheme and many others schemes in terms of system throughput for DL and outage probability according to the distance constraint. Simulation results show that the proposed scheme has better performance than the other resource allocation schemes performance in terms of the system throughput and outage probability. The paper will be organized as follows. In Section 2, we present the scenario description and system model. In Section 3, we propose a novel scheme to realize DL resources sharing avoiding interference ARIA for network assisted ad-hoc D2D communications. Section 4 presents the new way to determine the multi-hop D2D outage probability that is able to enhance the system performance. Finally, performance evaluation and discussions are presented in Section 5 and conclusion is given in Section 6.
