The vision of the fifth generation of mobile networks (5G) lies in bringing enhanced performances with respect to the previous mobile technologies. 5G has been planned to provide revolutionary high throughput, extremely low latency, for miscellaneous devices with massive and ubiquitous connections. To achieve these goals, many advanced technologies have been introduced and utilized in 5G, like massive MIMO, mmWave, efficient Radio Resource Management (RRM) techniques, etc. Among all, an efficient RRM could have a significant impact on effective spectrum utilization, massive connections. One thriving solution is represented by virtual Radio Access Network (vRAN) technology and is profitable in terms of cost and scalability for the mobile network operators.
