Today's world naturally depends on wireless devices for the daily necessities like
communication, smart car driving, smart medical check up, smart housing security, etc …

We consider a heterogeneous ultra dense network (HUDN) with both the hexagon and
Poisson point process (PPP) layouts, which is more relevant for practical scenarios. A user …

Driven by the vision of 5G communication, the demand for mobile communication services
has increased explosively. Ultra-dense networks (UDN) is a key technology in 5G. The …

In this paper, we propose a low complexity spectrum resource allocation scheme cross the
access points (APs) for the ultra dense networks (UDNs), in which all the APs are divided …

At present, inter-beam interference elimination has great development needs in multi-beam
mobile satellite communication. In this paper, based on the precoding technology research …

Heterogeneous ultra dense network (HUDN) is a promising technique to improve network
capacity for the fifth generation mobile communication system. However, HUDNs face the …

The performance of cloud radio access networks (Cloud-RAN) is constrained by the limited
fronthaul capacity. Physical layer caching is an effective technique to reduce the …

In ultra-dense cellular networks (UDNs) with user/control plane (U/C) splitting, frequent
handovers in user planes are unavoidable. This seriously degrades MS's transmission …
