“…Figure 6 illustrates the performance comparison of improved IWDs algorithm in terms of energy efficiency. Obviously, the energy efficiency obtained by employing the proposed algorithm is much higher than that of GA and Ant Colony Optimization (ACO) algorithm mentioned in [22]. That is, the better performance is achieved by using improved IWDs algorithm.…”

“…Figure 7 shows the relationship between energy efficiency and the distance between the users and BS, comparison of different resource allocation schemes. It is proven that the proposed improved IWDs algorithm obtains better performance than that of algorithms in [22]. At the same time, with the increasing of transmission distance, the energy efficiency is gradually reduced.…”

Appropriate resource allocation has great significance to enhance the energy efficiency (EE) for cooperative communication system. The objective is to allocate the resource to maximize the energy efficiency in single-cell multiuser cooperative communication system. We formulate this problem as subcarrier-based resource allocation and solve it with path planning in graph theory. A twolevel neural network model is designed, in which the users and subcarrier are defined as network nodes. And then we propose an improved intelligent water drops algorithm combined with Genetic Algorithm; boundary condition and initialization rules of path soil quantity are put forward. The simulation results demonstrate that the proposed resource allocation scheme can effectively improve the energy efficiency and enhance QoS performance.

“…The authors in [175] studied the relay selection for relay assisted LTE-advanced networks. The considered network assumes that the information exchange between user equipment and eNodeB is conducted using three possible transmission schemes, i.e., direct transmission, cooperative relaying, or a combination of network coding and cooperative relay.…”

To address the coverage and capacity challenges in fifth-generation (5G) wireless networks, the relay technique has been considered as a promising solution and recently attracted great attentions from academia. The multiway relay channel (mRC), which serves as a fundamental building block of a relay network, defines the family of all possible information-flow patterns between a relay node and its neighboring nodes. Combined with several new techniques, such as physical-layer network coding (PLNC), signal and interference alignments, multi-input multi-output (MIMO), etc., the mRC exhibits superior capability to assist multiuser information exchange. In this article, we aim to provide a comprehensive overview on the state-of-the-art of the mRC from the perspectives of both information-theoretic and communication-theoretic studies. The key results are summarized and discussed to identify the current research progress of the mRC. Open problems and research challenges are also discussed to spur future research towards the mRC.Index Terms-Multiway relay channel (mRC), physical-layer network coding (PLNC), multi-output multi-input (MIMO), degrees of freedom (DoF), precoding, relay selection.

“…Specifically, in the problem solving, the transmission mode selection and resource assignment are formulated as a job assignment problem which can be solved easily. Zainaldin et al [2] study the joint resource allocation and relay selection for bidirectional LTE-Advanced relay networks. In [2], the transmission mode selection is considered, and a three time slot scheme for time division duplexing (TDD) is proposed for LTE-Advanced frame architecture to accommodate a hybrid transmission scheme.…”

In this paper, we investigate the joint resource allocation for the non-orthogonal multiple access (NOMA)-enhanced relaying networks involving the subcarrier pair, subcarrier-user assignment, as well as power allocation. In the NOMA-enhanced relaying networks, the relay is capable of communicating with multiple users on one subcarrier using the NOMA technology. To maximize the system throughput, the joint resource allocation problem is formulated as a mixed-integer nonlinear programming problem, which is difficult to tackle in general. Furthermore, there is strong coupling between the subcarrier-user assignment and the power allocation due to the multiuser interference in the NOMA system. To reduce the complexity, we separate the joint resource allocation problem as two subproblems in terms of the subcarrier assignment (subcarrier pair and subcarrier-user assignment) and power allocation, respectively. In particular, we propose a subcarrier assignment scheme based on the simulated annealing algorithm to optimize the subcarrier pair and subcarrier-user assignment with the fixed power allocation. Then, the power allocation problem is transformed as a difference of convex functions programming problem, and the sequence convex programming method is adopted to solve it. The simulation results illustrate that the proposed algorithm can effectively improve the system throughput.
