Dynamic Hardware Resource Provisioning in Hybrid Radio Access Networks

This work uses the mobile network operators’ knowledge regarding mobile subscriber movement in the current infrastructure, i.e., Decentralized Radio Access Network (D-RAN), to dimension the infrastructure needed for the new generation of mobile infrastructure, i.e., Cloud/Centralized Radio Access Network (C-RAN). We propose a heuristic considering two approaches, one focused on the coverage of users and another focusing on the aggregated throughput. The performance assessment considers that the day is divided into three periods: working hours (morning), leisure hours (afternoon) and home hours (night). Results show that the heuristic allows mobile network operators to properly dimension the number of Small Cells (SCs) needed for a given area, maximizing the multiplexing and efficiency of the BaseBand Units (BBUs).
