    Priority Based Balancing Model of Resource Allocation in LTE Downlink
    (©Scholars Academic and Scientific Publisher, 2016) Лемешко, О. В.; Aymen Al-Dulaimi
    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.

    Realization of Resource Blocks Allocation in LTE Downlink in the Form of Nonlinear Optimization
    (2016) Aymen Al-Dulaimi; Mohammed Al-Dulaimi; Ageyev, D.
    In this paper proposed realization of resource blocks allocation in LTE downlink in the form of nonlinear optimization. In using improved model it is possible to avoid the control variables Boolean nature, which has a positive impact on the computational complexity of final technological solutions for resource allocation. Problem of RAT 1 was reduced to the problem solution of nonlinear optimization. In solving this problem minimized both the number of resource blocks used, and downlink bandwidth.
