Systems and methods for beamforming

Abstract

Systems and methods for beamforming include a device including at least one of a head wearable display (HWD) or a console. The device establishes a first connection between an active HWD radio-frequency integrated circuit (RFIC) and an active console RFIC. The device compares a modulation and coding scheme (MCS) of the first connection to an MCS threshold.The device performs MCS measurements for a second connection of at least one of an idle HWD RFIC or an idle console RFIC, while the first connection is maintained, in response to the MCS not satisfying the MCS threshold. The device compares the MCS measurements of the second connection to the MCS threshold. The device switches to the second connection when at least one of the one or more MCS measurements satisfies the MCS threshold and/or above the MCS of the first connection.
