Query: InferBeam: A Fast Beam Alignment Protocol for Millimeter-wave Networking   We introduce fast millimeter-wave base station (BS) and its antenna sector
selection for user equipment based on its location. Using a conditional random
field inference model with specially designed parameters, which are robust to
change of environment, InferBeam allows the use of measurement samples on best
beam selection at a small number of locations to infer the rest dynamically.
Compared to beam-sweeping based approaches in the literature, InferBeam can
drastically reduce the setup cost for beam alignment for a new environment, and
also the latency in acquiring a new beam under intermittent blockage. We have
evaluated InferBeam using a discrete event simulation. Our results indicate
that the system can make best beam selection for 98% of locations in test
environments comprising smallsized apartment or office spaces, while sampling
fewer than 1% of locations. InferBeam is a complete protocol for best beam
inference that can be integrated into millimeter-wave standards for
accelerating the much-needed fast and economic beam alignment capability.
