Virtual reality (VR) applications are becoming increasingly popular in both entertainment and commercial industries. Improving the immersive experience is essential to meet the expectations of users. To achieve the highest quality of experience (QoE), various factors such as delay, refresh rate, and data rate must be considered. Streaming only the field of view (FoV) of users based on gaze movement is a common method to improve the performance of end-to-end (E2E) delay. In this paper, we propose a novel non-overlapped tile streaming approach with dynamic resource allocation in VR networks to enhance the E2E delay with efficient resource block (RB) utilization. Our approach exploits the existence of overlapping tiles in consecutive FoV requests for reducing the number of tiles that need to be transmitted to users. By combining the non-overlapped tile streaming scheme with the flexible resource allocation, our proposed approach provides VR users with an enhanced QoE, particularly in terms of shorter E2E delay.
