“…Contrary to in-band D2D communication, it is infeasible to control interference using an out-band approach. Out-band Controlled communication and autonomous communication are two types of D2D communication [97]. In the former case, the cellular network is in charge of and controls the D2D communication.…”

Due to the vast rise of users, the variety of application requirements, and the enormous necessity for ubiquitous connectivity anytime and anywhere, integration of new technologies and ideas are required. Therefore, Device to Device (D2D) communication technology has been regarded as a critical concern for Beyond Fifth Generation (B5G) networks. In the D2D technology, devices in close proximity may connect without using a Base Station (BS). Consequently, improving the capacity and performance of traditional networks. The major objectives are to accomplish a high geared data rate, increase the network coverage with low latency, and improve Energy Efficiency (EE) and Spectrum Efficiency (SE). However, the coexistence of D2D technology in the traditional network can pose many issues and challenges, such as power control, interference, spectrum access, security, and mode selection. Consequently, a comprehensive survey that includes an investigation of the current issues in D2D technology is required. In this survey, we present a new categorization of the most important aspects of resource management in B5G D2D communication, such as power allocation, spectrum allocation, interference management, and mode selection. Furthermore, we discuss the limitations and open issues of the current techniques and propose a model approach and future directions for D2D communication in B5G wireless networks. Our survey aims to assist researchers in exploring and improving D2D communication within the framework of forthcoming wireless networks.

From the above literature, we can conclude that the tradeoff between SE and EE in NOMA HetNets has not been investigated sufficiently, where both co-tier and crosstier interference contribute to the PC problem.…”

In this paper, the tradeoff between spectrum efficiency (SE) and energy efficiency (EE) is investigated in terms of interference management and power allocation for heterogeneous networks (HetNets) with non-orthogonal multiple access (NOMA). The EE and SE tradeoff is modeled as a multiobjective problem (MOP) under the maximum power and quality of service (QoS) constraints, which is non-convex. The MOP is relaxed into a convex single objective problem (SOP) by adopting a weighted sum strategy with the hypograph transformation. The SOP is solved in two steps. In the first step, we propose a power allocation technique based on non-cooperative (NC) game for EE and SE in NOMA HetNets. In the proposed NC game, the macro base station (MBS) and the small BSs (SBSs) compete with an equal priority in order to optimize their transmit powers towards maximizing the weighted sum of SE and EE. In the second step, a closed-form formula is proposed to control the power allocated to users taking into account both QoS constraint and successive interference cancellation (SIC) condition. From simulations, the proposed technique can, in some dedicated settings, considerably improve the tradeoff between EE and SE over conventional techniques.INDEX TERMS Heterogeneous networks (HetNets), energy efficiency (EE), spectrum efficiency (SE), interference mitigation, power control (PC), non-cooperative (NC) game .

“…Common single-node spectrum sensing algorithms include energy detection (ED) [10][11][12][13][14][15][16], matching filters [17][18][19][20], cyclic stationary detection [21][22][23], and compressive spectrum sensing [24,25], and they have different requirements, advantages, and disadvantages. The ED algorithm has low complexity, is based on a simple principle, and is easy to implement.…”

Matching filtering has been proven to be the optimal spectrum sensing algorithm under Gaussian white noise. However, the application of this algorithm is limited because of its dependence on prior information. In this paper, we propose a spectrum sensing algorithm based on blind matching filtering (BMF) by using the correlation between adjacent received signals under dispersive channels. Theoretical analysis shows that the proposed algorithm can achieve a performance comparable to that of the matching filtering algorithm without requiring the prior information of the primary user. Thus, this algorithm shows superior detection performance. Moreover, an improved BMF (IBMF) algorithm is proposed on the basis of the correlation between different time-delay signals. IBMF utilizes more comprehensive correlation information of the received signals and achieves better detection performance compared to BMF. Furthermore, the two proposed algorithms have lower computational complexity than the classical approaches based on the covariance matrix of the received signals. Numerical simulations confirm the superior performance of the proposed detectors and validate the theoretical analysis.
