Fairness and User Assignment in Cloud-RAN

2017 IEEE 86th Vehicular Technology Conference (VTC-Fall), 2017
In this paper, we extend our previous work on user assignment in Cloud-RAN, where we proposed an algorithm for user assignment (UA). We motivate the inherent fairness issue that is present in the latter UA scheme, since some users in the system will never get served. For that purpose, we propose two schemes to be used in conjunction with aforementioned
