Resource Allocation in Heterogeneous Cognitive Radio Network With Non-Orthogonal Multiple Access

Resource Allocation in Heterogeneous Cognitive Radio Network With Non-Orthogonal Multiple Access

In this paper, we study resource allocation problems for a two-tier cognitive heterogeneous network in interweave spectrum sharing mode. Secondary users (SUs) in small cells (SCs) opportunistically access the licensed spectrum resources. Non-orthogonal multiple access (NOMA) is used to boost the num...
