Device-to-device (D2D) communication is a promising and rapidly evolving technology and it plays a significant role in reducing pressure on the base station. In this paper, we focus on how to achieve the goal of maximizing system throughput by adjusting the transmitted power of each D2D user. Due to the uncertainty of channel states and state transition probabilities, this problem can be modeled as the reinforcement learning (RL) algorithm. We first use the fuzzy clustering algorithm to group D2D users of which the attribute values are in a large dissimilarity so as to reduce interference, then each group is treated as an agent in the RL algorithm. Therefore, a multi-agent RL based on fuzzy clustering algorithm is established. Finally, we verified the superiority of the proposed algorithm through simulations.

In this paper, we investigate resource allocation algorithm design for secure non-orthogonal multiple access (NOMA) systems empowered by wireless power transfer. With the consideration of an existing eavesdropper, the objective is to obtain secure and energy efficient transmission among multiple users by optimizing time, power and subchannel allocation. Moreover, we also take into consideration for the practical case that the statistics of the channel state information of the eavesdropper is not available. In order to address the optimization problem and its high computational complexity, we propose an iterative algorithm with guaranteed convergence to deliver a suboptimal solution for general cases. For some special cases, the solution ensures the global optimum. Numerical studies demonstrate the competitiveness of the proposed algorithmic solution over conventional orthogonal multiple access systems as well as over other existing NOMA resource allocation schemes.

Geo-location database is an efficient way to delivery the spectrum occupancy information, which is defined as "cognitive information", to unlicensed users in cognitive radio networks (CRNs). In this paper, we study the compression of cognitive information in geo-location database supported CRNs. We propose a delaunay triangulation based triangle mesh division algorithm. It is proved that the RPE of triangle meshes is smaller than that of rectangle meshes when the number of meshes are the same. Then the triangle meshes are clustered to reduce the redundancy of cognitive information. Finally, the boundaries of the clusters are extracted, which form polygons and the cognitive information is further compressed. The numerical results are provided to verify the correctness of the theoretical analysis and the efficiency of the cognitive information compression algorithms.

In this paper, we propose a novel M-ary frequency shift keying (MFSK) modulation scheme for the Tag in ambient backscatter communications system. Leveraging on the frequency shifting feature of the MFSK modulation, the direct interference from the ambient RF signal is removed with the assistance of a set of band-pass filters. A simple energy detector is proposed for symbol detection according to the post-filter signals. Closed-form expressions for the symbol error rate (SER) and outage probability of the system are derived, based on which, the modulation order, operating signal-to-noise ratio (SNR), and the tag location is optimized. The findings of the paper suggest that the impact of modulation order on the SER performance depends heavily on the operating SNR, and the optimal modulation order exhibits a binary behavior.

In a dynamic time division duplex multi-cell system, the uplink (UL) and downlink (DL) transmissions may co-exist. The asymmetric UL-DL modes introduce more complex and diverse interference among the adjacent cells. In this paper, we propose an interference alignment (IA) scheme for asymmetric UL-DL multi-cell multi-user multi-antenna system. This system involves conventional inter-cell and intra-cell interference in symmetric directions and new asymmetric inter-cell interference. We characterize the properties of the new interference and use these properties to implement partial IA and guarantee feasibility of IA. Through minimizing weighted sum minimum mean square error, we design a regularized IA transceiver to compensate the performance degradation in low and moderate signal-noise-ratio region. The numerical simulations demonstrate that the proposed schemes outperform the previous works for the asymmetric UL-DL multi-cell system.

To develop the future intelligent intersection vehicular traffic management strategies in automated vehicle era, increasing attentions have been paid to the non-signalized intersection scenarios by leveraging the connected vehicle techniques. In the paper, we present an optimal automated vehicle traffic scheduling solution to non-signalized intersection management to maximize the intersection throughput without collision risk. First, we formulate the collision-free vehicular traffic scheduling problem, in which a general vehicular traffic arrival model considering both individual vehicle and platoon cases has been developed. Furthermore, a heuristic algorithm is proposed to calculate the optimal entering time of each automated vehicle and enhance the efficiency of the intersection management to the utmost extent, namely optimal entering time scheduling (OETS) algorithm. Simulation results demonstrate that the proposed OETS algorithm can significantly reduce the traffic delay and is much efficient than traditional traffic lights.

Recently, as the benefit of its compelling applications, vehicle-to-everything (V2X) communications have attracted more and more attentions. Non-orthogonal multiple access (NOMA) provides a new solution for V2X services to ease traffic congestion and reduce latency. Different from existing works, we propose two NOMA-based schemes for V2X broadcasting and multicasting, and investigate the power allocation problems for them. The power allocation problems are formulated to maximize the minimum achievable vehicle rate for the purpose of fairness. In addition, we show that the formulated problem is neither convex nor concave. Fortunately, it is shown that the considered problem is quasi-concave, and hence we obtain the solution to the problem by a power allocation algorithm based on a bisection procedure. Simulation results demonstrate that the proposed scheme out-performs the scheme with fixed power allocation obviously and achieves a significant performance improvement with respect to a suboptimal fractional transmit power allocation (FTPA) method and the optimized time division multiple access (TDMA) scheme.

While increasing access points(APs) densification is considered as a useful solution to cater for the explosive growth of throughput demands, its impact on the handover needs to be carefully handled. In order to reduce unnecessary handover and improve the users’ experience, this paper proposes an optimal AP selection algorithm for the mobile user based on mobility prediction. According to the historical data of the mobile user, we use a semi-Markov model with finite conditions to predict the user’s next possible location. Then, according to the user’s demand for network resources, the most suitable AP is selected based on the proposed optimization model in the expected location. The proposed handover scheme selects the best AP connectivity, by skipping handover of some APs along the moving trajectory. Simulation results show that the proposed scheme achieves a better performance compared with existing schemes in terms of the prediction accuracy.

In this paper, we propose a novel Cooperative Non-orthogonal Division Multiple Access (NOMA) based Visible Light Communication (VLC)/Radio Frequency (RF) system with Simultaneous Wireless Information and Power Transfer (SWIPT). In the proposed system, the Near User (NU) not only receives information but also harvests the energy from the light signals emitted by LED. The harvested energy is then utilized by NU to forward the information to the Far User (FU) who cannot directly communicate with LED through RF channel. To support such cooperative multi-user transmission, NOMA is adopted. We analyze the outage performance of both NU and FU and discuss the impact of Power Splitting (PS) ratio on the performance. It was found through theoretical analysis and numerical results that one can trading off the outage performance of users through PS ratio. In addition, there exists the optimal design of PS ratio which can minimize the outage probability of users.
