The unprecedented growth of wireless data traffic not only challenges the design and
evolution of the wireless network architecture, but also brings about profound opportunities …

Fully cloudified mobile network infrastructure, which is featured by the joint deployment of
heterogeneous cloud radio access networks and edge computing, will successfully cope …

Beam hop** (BH) is considered to provide a high level of flexibility to manage irregular
and time-varying traffic requests in future multi-beam satellite systems. In BH optimization …

In ultra-dense heterogeneous networks, caching popular contents at small base stations is
considered as an effective way to reduce latency and redundant data transmission …

In this paper, we investigate the problems of sum power minimization and sum rate
maximization for multi-cell networks with non-orthogonal multiple access. Considering the …

Optimizing non-orthogonal multiple access (NOMA) in multi-cell scenarios is much more
challenging than the single-cell case because inter-cell interference must be considered …

Low earth orbit (LEO) satellite-assisted communications have been considered as one of the
key elements in beyond 5G systems to provide wide coverage and cost-efficient data …

In this paper, we study a class of minimum-energy scheduling problems in non-orthogonal
multiple access (NOMA) systems. NOMA is adopted to enable efficient channel utilization …

In this paper, we minimize the transmit power for multiple-input single-output and
nonorthogonal multiple access systems. In our analysis, a large number of users are …

Multi-connectivity is emerging as promising solution to provide reliable communications and
seamless connectivity at the millimeter-wave frequency range. Due to the obstacles that …
