標題: Immersive Cloud VR Gaming and Beyond

Cloud VR gaming shifts computationally intensive games to cloud servers, alleviating strain on Head-Mounted Displays. Yet, ensuring high-quality experiences faces challenges like human perception complexities and network variability. We introduce dynamic foveation techniques to enhance gamer Quality of Experience (QoE) by prioritizing resources to foveal regions, improving visual fidelity and bandwidth usage. We next present predictive models to adjust encoding settings for better gamer QoE. Our studies stream 2D video codecs from cloud servers to HMD clients, with the potential for emerging 3D representations. Along that direction, we share a novel error concealment pipeline for dynamic 3D point clouds, enhancing streaming quality under high packet loss rates. These advancements in cloud VR gaming open avenues for future research and development.

標題: Beam Prediction for Mobile Users in mmWave Communications

The vast availability of Millimeter wave (mmWave) spectrum holds the promise of data rates several tens of times faster than those of mid- and low-bands. However, a significant challenge of mmWave communication lies in the severe propagation loss, necessitating compensation through directional beamforming. Accurate beamforming becomes particularly challenging in scenarios involving user movement. This talk begins by elucidating the fundamental principle of beam alignment, outlining its importance in mmWave communication systems. Subsequently, it introduces a novel approach that harnesses the predictive capability of machine learning (ML) models to achieve high beam alignment accuracy. Through this innovative method, the talk aims to address the challenges posed by user mobility in mmWave communication systems.
