  In this paper, a novel proactive computing and mmWave communication for
ultra-reliable and low latency wireless virtual reality (VR is proposed. By
leveraging information about users' poses, proactive computing and caching are
used to pre-compute and store users' HD video frames to minimize the computing
latency. Furthermore, multi-connectivity is exploited to ensure reliable mmWave
links to deliver users' requested HD frames. The performance of the proposed
approach is validated on a VR network serving an interactive gaming arcade,
where dynamic and real-time rendering of HD video frames is needed and impulse
actions of different players impact the content to be shown. Simulation results
show significant gains of up to $30\%$ reduction in end-to-end delay and $50\%$
in the $90^{\textrm{th}}$ percentile communication delay.
