Overview

In this project, we propose to innovate the 5G technology in its software stack (in the form of protocols) from the device side. We use robotic applications to drive our design effort. We challenge the conventional wisdom that wireless access is the sole roadblock for low latency and high reliability. Instead, we take the device perspective on 5G software innovation, which poses as an equally critical pathway from our initial results. We propose three concrete research thrusts: (1) we refine the software stack of 5G for low latency without the standards framework from the device side. (2) we improve high reliability through device-centric software techniques on the 5G system. (3) we provision 5G devices with new capabilities of both learning and reasoning for both common usage settings and failure-prone scenarios.
