1. A method, comprising:
obtaining motion data from one or more motion sensors coupled to a wireless device;
determining, based at least on the motion data, that the wireless device is static relative to a remote device that is in communication with the wireless device using a beam generated by the wireless device;
obtaining data representing one or more link metrics of the beam, the one or more link metrics being associated with a period of time that the wireless device is static;
determining, from the one or more link metrics, a link stability value associated with the beam, for the period of time that the wireless device is static;
determining that the wireless device is out of coverage (OoC) with respect to the remote device based on the link stability value associated with the beam;
in response to determining that the wireless device is OoC with respect to the remote device, selecting a first beam group including one or more first beams generated by the wireless device;
determining, for each beam of the first beam group, a respective link stability value for the beam;
selecting, based on the determining, a particular beam of the one or more first beams; and
reestablishing communication with the remote device using the particular beam.
