Over the last few years, interference has been a major hurdle for successfully implementing
various end-user applications in the fifth-generation (5G) of wireless networks. During this …

The integration of cognitive radio (CR) technology and non-orthogonal multiple access
(NOMA) techniques, referred to as CR-based NOMA systems, has been recently configured …

Non-orthogonal multiple access (NOMA)-based cognitive radio (CR) networks have recently
emerged as a promising solution to enhance the spectral efficiency and massive …

This paper investigates outage and throughput performance of non-orthogonal multiple
access (NOMA) based underlay cognitive radio (ie, CR-NOMA) network under partial relay …

The stringent requirements of wireless multimedia transmission lead to very high radio
spectrum solicitation. Although the radio spectrum is considered as a scarce resource, the …

In this paper, we consider a Q-learning-based power allocation strategy for a secure
physical-layer system under dynamic radio environments. In such a system, the transmitter …

In a conventional cognitive radio (CR) network, only when the primary user's (PU) frequency
bands are sensed to be free, secondary users (SUs) can utilize these frequency band …

The fresh and rising demands for high-reliability and ultrahigh-capacity wireless
communication have led to extensive research into 5G communications. The wide progress …

Resource allocation (RA) is a key technique to guarantee the quality of service of users and
maximize the system capacity in cognitive nonorthogonal multiple access (NOMA) networks …

We investigate a distributed caching strategy based on multi-agent reinforcement learning
(MARL) in a cache-aided network, where all wireless nodes have limited storage capacity …
