Priority Based Balancing Model of Resource Allocation in LTE Downlink

Abstract

Investigation of priority based balancing model of resource allocation in LTE downlink supporting RAT 1 presented. The novelty of model is that it can be used to describe the process of resource blocks allocation in LTE downlink given user equipments requests priority. Using the model allows to optimize the process of resource allocation in LTE downlink in solving the problem by mixed-integer linear programming. The advantage of the model is that the balancing of resource blocks number allocated to each of user equipments is performed based on QoS requirements: demanded bit rate, priority and resource type (with or without guarantee). Results of research confirmed the efficiency of model and adequacy of obtained on its basis solutions.
