Utility-Based Opportunistic Scheduling Under Multi-Connectivity With Limited Backhaul Capacity

Multi-connectivity is a 5G key enabler to fulfill multi-service quality-of-service (QoS) requirements. This letter examines an opportunistic resource allocation problem under multi-connectivity and limited backhaul capacity in evolved LTE using two utility functions: 1) proportional fairness (PF) and 2) utility proportional fairness (UPF). We then propose an efficient algorithm to deal with the fo...
