Deep Reinforcement Learning-Based Resource Allocation for QoE Enhancement in Wireless VR Communications

Abstract

Wireless virtual reality (VR) communication applications have emerged as a transformative technology, offering innovative solutions in various areas of everyday life. However, the successful deployment of these applications faces challenges in ensuring high quality of experience (QoE), especially in environments with limited network resources. This research paper presents a novel approach to address the challenge of enhancing QoE by incorporating deep reinforcement learning (DRL) techniques in the resource allocation process. The proposed model takes into account the quality of service (QoS) parameters of the 5G new radio (NR) network to optimize its operation, ensuring a seamless and immersive VR experience. Specifically, the resource allocation strategy adopts a policy that maximizes the transmission-related QoE value based on the evolving characteristics of the communication channel and user interactions. To evaluate the effectiveness of the proposed approach, extensive simulations and comparative analyses against traditional resource allocation methods are performed. The results demonstrate significant improvements in the transmission-related QoE values and highlight the superiority of the DRL-based resource allocation approach in the dynamic and unpredictable wireless environments.
