Abstract
An apparatus and related operating method of a mmWave WHMD, are provided. The apparatus utilizes beamforming information to determine direction information indicating a direction of a received signal from an external component that is connected to the apparatus via a VR data link. The apparatus selects and sets a current MCS that supports a data load of the VR data link. The apparatus, while maintaining the VR data link, determines a VR data link condition by a determination that a received signal is stronger or weaker than a predetermined signal strength level for the current MCS of the VR data link. When stronger, the processing circuitry is configured to signal a transceiver to widen a beam from a current beamwidth to a new wider beamwidth in a direction based on the direction information to maintain the current MCS and data load of the VR data link.
