“…Our goal is to maximize the the users' utility function considering the traffic load, so the reward can be assigned as the sum value of the users' utility function as expressed in (11). The learning process is driven by the reward function in the RL framework, and the system performance can be improved when the design of the reward function for each step is related to the desired objective.…”

The network-assisted full-duplex (NAFD) system realizes flexible duplex in the spatial domain within the same time-frequency resource. With the explosive growth of the number of users and remote antenna units (RAUs) under 6G scenario, the resource utilization of the system is lower. When the resource of users is selected by the RAUs to send or receive, collisions or congestion may occur due to mechanisms such as grant-free. Aiming at making better use of system resources, a load-aware dynamic mode selection scheme with NAFD scheme is proposed to improve the access efficiency and resource utility of the system. This paper first propose a centralized Q-learning algorithm which determines a clever strategy to approach the ultimate goal by itself and excels in environment dynamics. However, the size of the Q-table used in the centralized Q-learning algorithm for storage is huge. Further, a distributed multi-agent Q-learning algorithm is proposed which has a smaller size of Q-table and lower complexity to suit for actual scenarios. The simulation results showed that the proposed load-aware dynamic mode selection scheme can significantly improve resource utility and throughput performance than other traditional schemes.

“…As a result, the concept of simultaneous wireless information and power transfer (SWIPT) was introduced in [22]. In recent years, SWIPT has aroused great interest in wireless communication networks [23]- [28], and has also been considered in networked control systems [29]. In [29], a novel power control problem for remote state estimation was formulated, where the signal transmitted by the remote estimator served as the energy source of the sensor, and the transmission power allocations of the remote estimator and the sensor are jointly optimized.…”

“…These days due to massive IoT (mIoT) deployment, NOMA is now becoming a more favourable and feasible multiple access (MA) technique than conventional OMA. An energy-efficient simultaneous wireless information and power transfer (SWIPT)-assisted NOMA system was presented in [15][16][17][18] and [19] in order to deal with spectrum sensing overhead and battery draining issues of cognitive radio (CR) network, and to enable massive connectivity at underutilized spectrum. [20], [21] applied NOMA for the massive connectivity and explored energy efficiency (EE) of mobile edge computing (MEC) in IoT networks.…”

The fifth-generation (5G) of cellular technology is currently being deployed over the world. In the next decade of mobile networks, beyond 5G (B5G) cellular networks with the under-development advanced technology enablers are expected to be a fully developed system that could offer tremendous opportunities for both enterprises and society at large. B5G in more ambitious scenarios will be capable to facilitate much-improved performance with the significant upgrade of the key parameters such as massive connectivity, ultra-reliable and low latency (URLL), spectral efficiency (SE) and energy efficiency (EE). Equipping non-orthogonal multiple access (NOMA) with other key drivers will help to explore systems' applicability to cover a wide variety of applications to forge a path for future networks. NOMA empowers the networks with seamless connectivity and can provide a secure transmission strategy for the industrial internet of things (IIoT) anywhere and anytime. Despite being a promising candidate for B5G networks a comprehensive study that covers operating principles, fundamental features and technological feasibility of NOMA at mmWave massive MIMO communications is not available. To address this, a simulation-based comparative study between NOMA and orthogonal multiple access (OMA) techniques for mmWave massive multiple-input and multiple-output (MIMO) communications is presented with performance discussions and identifying technology gaps. Throughout the paper, aspects of operating principles, fundamental features and technological feasibility of NOMA are discussed. Also, it is demonstrated that NOMA not only has good adaptability but also can outperform other OMA techniques for mmWave massive MIMO communications. Some foreseeable challenges and future directions on applying NOMA to B5G networks are also provided.
