A Fairness-Based Preemption Algorithm for LTE-Advanced

In this paper, the authors propose a fairness-based preemption algorithm for 3GPP LTE-Advanced. It considers bearers' priorities as well as their QoS over-provisioning with respect to their minimum QoS needs into the partial preemption decision. They define a preemption contribution metric for each established bearer and they evaluate the proposed scheme both in terms of inter- and intra-priority preemption fairness. Through a simulation approach, they conclude substantial improvements in preemption fairness when compared to a traditional preemption approach. They discuss that the proposed scheme does not affect the main performance measurements of the network, i.e. the bearers' blocking and dropping probabilities due to congestion.
