1. A method, comprising:
determining, based on motion data from a motion sensor coupled to a wireless device, that a channel is stable for communications between the wireless device and a remote device;
selecting, from a set of available beams, a set of candidate beams;
for a candidate beam of the set of candidate beams, establishing signaling for a physical downlink shared channel (PDSCH);
determining a modulation and coding scheme (MCS) threshold set by the remote device for the PDSCH signaling;
estimating, based at least on the MCS threshold, a channel capacity of the PDSCH; and
selecting, based at least on the estimated channel capacity, a particular beam from the set of candidate beams, for further PDSCH communication.
