We consider an ultra-dense network where each mobile is attached to the access point, which provides the best reference signal received power considering both path-loss and small-scale fading. In order to evaluate the effect of outdated channel state information (CSI) brought by feedback delay, we first derive the estimated and accurate handover probability according to outdated and perfect CSI, respectively...
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...
