Abstract
In this paper, we propose a cooperating scheme to maximize network throughput while guaranteeing user quality of experience (QoE) demands in multiple-input-multiple-output (MIMO) systems. One of the aspired-to targets of the fifth generation (5G) network is to boost QoE everywhere, especially in the cell-edge areas. User equipments (UEs) in the edge areas are vulnerable to QoE violations, and they need dual connectivity from two nearby transmission points. Hence, UEs are categorized into two groups: single-connectivity and dual-connectivity. After classification, transmission power is allocated to maximize the network capacity while guaranteeing the minimum QoE. By comparing performance with a single connectivity-based algorithm and a fixed multi-connectivity-based algorithm, we show that our proposed algorithm not only satisfies all the UEs in the system but also maximizes the network capacity.
