Abstract

Virtual cell (VC) is an emergent concept in cellular networks that shifts the base-station-centric point of view to a user-centric one. Instead of traditional base station assignment, VCs contain a number of transmission points with an association pattern that is created for, and moves with, every user in the network. This study targets VCs for vehicle-To-everything (V2X) communications, where V2X messages are broadcast to groups of vehicles. We extend the VC concept to broadcast groups and form VCs for hotspots (HSs) of vehicles. Our goal is to serve a maximum number of HSs sharing the same radio resource, with as little energy as possible, while guaranteeing a certain communication reliability to the served vehicles. The proposed solution consists of three optimization stages, which are the admission control, the transmission weight selection and the power control. Performance of the solution is assessed by investigating the impact of various system-level parameters, and compared with baselines. Results promise an increased capacity, reliability and power efficiency of the network.
