Feedback delay can severely impact network performance in mobile network and the theoretical quantification of performance degradation has attracted much research interest recently. In this paper, we conduct coverage analysis of mobile ultra-dense networks (UDNs) where coordinated multipoint (CoMP) technology is adopted to enhance network performance and the available channel state information (CSI)...
Caching popular contents in the storage of users is deemed as an efficient approach to increase energy efficiency, decrease latency, as well as offload backhauls. Due to the mobility feature of use terminals in the real environment, the analysis of successful transmission is particular important in mobile networks. In this paper, the position of cache-enabled users are distributed as a Homogeneous...
This paper conducts handover probability analysis in Coordinated multipoint (CoMP) based ultra-dense networks (UDNs) where access points (APs) jointly serve the user. To thoroughly investigate the effect of mobility on handover probability, we compare several handover schemes of CoMP coordinating set (CCS) handover and serving cell handover. From the perspective of CCS handover, three schemes are...
Directed influence between multiple channel signal measurements is important for the understanding of large dynamic systems. This research investigates a method to analyze large, complex multi-variable systems using directional flow measure to extract relevant information related to the functional connectivity between different units in the system. The directional flow measure was completed through...
