Densification of network base stations is indispensable to achieve the stringent Quality of
Service (QoS) requirements of future mobile networks. However, with a dense deployment of …

In order to counteract the explosive escalation of wireless tele-traffic, the communication
spectrum has been gradually expanded from the conventional radio frequency (RF) band to …

Ultra-dense networks (UDNs) constitute one of the most promising techniques for supporting
the 5G mobile system. By deploying more small cells in a fixed area, the average distance …

A 5G wireless network requires an efficient approach to effectively manage and segment the
resource. A Centralized Radio Access Network (CRAN) is used to handle complex …

Radio resource management (RRM) for future fifth-generation (5G) heterogeneous networks
(HetNets) has emerged as a critical area due to the increased density of small-cell networks …

With the increase of access point (AP) density and the exponential growth of mobile devices
supported by ultradense networks (UDNs), user-centric overlapped clustering relying on AP …

This paper considers the unavailability of complete channel state information (CSI) in ultra-
dense cloud radio access networks. The user-centric cluster is adopted to reduce the …

The ultra-dense cloud radio access network (UD-CRAN), in which remote radio heads are
densely deployed in the network, is considered. To reduce the channel estimation overhead …

This paper studies user-specific clustering for a downlink cloud radio access network (C-
RAN), where a central unit (CU), connected to all base stations (BSs) via limited-capacity …

The weighted sum-rate maximization problem of ultra-dense cloud radio access networks is
considered. The user-centric clustering is adopted for reducing the complexity. To reduce …
