Title: "Sometimes Less is More: Guessing one's way to reduced blockage"

Abstract: High frequency (mmWave and higher) systems are being used for curb-to-home systems and indoor networks. In these systems, the transmitter and receiver positions are generally fixed, while the environment between the transmitter and receiver can shift suddenly and cause blockages.  Using two simultaneous narrow beams can mitigate the blockage due to pesky animals and leaves. However, a phase and time delay can cause a drop in rate.  This talk discusses a simple 1-bit feedback system that guesses the a phase and delay that is good enough to increase the transmission rate.  As the received channel can change quickly due to blockages and thus require a different transmission rate, we propose a low-complexity feedback system that adjusts the transmission rate so that when one of the beams is blocked, an outage is prevented.
