Fully immersive virtual reality (VR) applications require ultra-high data rates and time-varying viewport rendering to ensure smooth operation. Therefore, this letter proposes a mobile edge computing-assisted wireless VR streaming transmission scheme to pursue a better quality of experience (QoE) and alleviate the computing burden of VR users. Our goal is to minimize the weighted energy consumption and distortion while ensuring the required QoE. The formulated problem is NP-hard and involves the optimization of quantization parameters, rendering offloading decisions, transmit precoding, and computing resource allocation. Simulation results validate the efficiency of the proposed algorithm in terms of the QoE performance.
