In millimeter wave (mmW) dense femto-networks, major challenges are overcoming the
performance loss imposed by the channel and managing the co-channel interference. The …

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 …

In this paper, we consider the network utility maximization problem with various user
priorities via jointly optimizing user association, load distribution, and power control in a load …

In this paper, we consider the problems of minimizing sum power and maximizing sum rate
for multicell networks with load coupling, where coupling relation occurs among cells due to …

In a cloud radio access network (C-RAN), distributed remote radio heads (RRHs) are
coordinated by baseband units (BBUs) in the cloud. The centralization of signal processing …

Cloud-based Radio Access Network (C-RAN) is a promising architecture for future cellular
networks, in which Baseband Units (BBUs) are placed at a centralized location, with …

Small cells deliver cost-effective capacity and coverage enhancement in a cellular network.
In this work, we present the interplay of two technologies, namely Wi-Fi offloading and small …

Ultra-dense SCNs have been regarded as a promising technology to handle the future data
traffic explosion. However, the complicated relationships among large scale users and cells …

This paper aims at network utility maximization via jointly optimizing user association,
resource allocation and power control in a load-coupled heterogeneous network. We first …
