User Allocation Algorithm with Rate Guarantees for Multi-rate Mobile Networks with Backhaul Constraints

This paper has presented a BS assignment algorithm that takes into account radio and backhaul constraints in allocating users from different service classes. The authors concentrate in scenarios where few base stations have limited backhaul capacity. A user from each service class requires to be served with a fixed data rate transmission in the downlink. They use a utility-based framework to quantitatively translate user (e.g., resource consumption) or operator benefits (i.e., revenue) into a utility function. It has been shown that with the presented algorithm users are likely to be attracted towards the BS with less loaded radio and backhaul constraint and the number of user assignment is increased.
