The authors consider the multiuser cognitive radio network, where a primary link coexists
with multiple secondary transmitters (STs) which intend to communicate with an access point …

In cooperative cognitive radio networks (CCRNs), through cooperating with primary
transmissions, secondary users (SUs) could access the spectrum resource when primary …

With wireless resource virtualization, multiple Mobile Virtual Network Operators (MVNOs)
can be supported over a shared physical wireless network and traffic loads in a Base Station …

Cognitive radio is regarded as the ideal candidate for enhancing the efficiency of spectrum
usage for next-generation wireless systems. In fact, this emerging technology allows …

In this paper, we consider the problem of hierarchical bandwidth sharing in cognitive radio
(CR) environment. In the system model under consideration, a primary service provider …

In this paper, we present a novel power allocation scheme for multicarrier cognitive radio
networks. The proposed scheme performs subchannel power allocation by incorporating …

We develop a framework based on deep reinforcement learning (DRL) to solve the spectrum
allocation problem in the emerging integrated access and backhaul (IAB) architecture with …

Radio spectrum underutilization and energy inefficiency become urgent bottleneck problems
to the sustainable development of wireless technologies. The research philosophies of …

One of the many problems faced by current cellular network technology is the
underutilization of the dedicated licensed spectrum of network operators. An emerging …

Cooperative Communications in Cognitive Radio (CR) have been introduced as an
essential and efficient technique to improve the transmission performance of primary users …
