Demo and dataset for mmWave multi-beam tracking using mMobile 28 GHz testbed

Abstract

Constructive multi-beam communication for mmWave is a new trend where the base station utilizes multiple paths to improve link throughput and reliability. This demo addresses a key challenge on maintaining a mmWave multi-beam link under user mobility. Traditional user-tracking algorithms for single-beam links do not directly apply to a multi-beam link due to large probing overhead. We demonstrate a low-overhead channel-based solution that only requires multi-beam channel estimates in the background to track multi-beams. We collect and release a one-of-its-kind channel dataset using our 28 GHz mMobile testbed.
