This paper provides an overview of cognitive radio (CR) networks, with focus on the recent
advances in resource allocation techniques and the CR networks architectural design. The …

This article surveys different resource allocation algorithms developed for the downlink of
multiuser OFDM wireless communication systems. Dynamic resource allocation algorithms …

Multitenant cellular network slicing has been gaining huge interest recently. However, it is
not well-explored under the heterogeneous cloud radio access network (H-CRAN) …

The emerging non-orthogonal multiple access (NOMA), which enables mobile users (MUs)
to share same frequency channel simultaneously, has been considered as a spectrum …

The mitigation of intercell interference is an importance issue for current and next-generation
wireless cellular networks where frequencies are aggressively reused and hierarchical …

Orthogonal frequency division multiplexing (OFDM) with dynamic scheduling and resource
allocation is a key component of most emerging broadband wireless access networks such …

We present a design of a complete and practical scheduler for the 3GPP Long Term
Evolution (LTE) downlink by integrating recent results on resource allocation, fast …

The utilization of licensed spectrum provides an opportunity to the cognitive users to utilize
these spectrum bands when unused by the primary users (PU x). The possibility of spectrum …

Since non-orthogonal multiple access (NOMA) with successive interference cancellation
(SIC) can achieve superior spectral-efficiency and energy-efficiency, the concept of SCN …

The fifth generation mobile networks will be developed to improve area spectral and energy
