Beam Tracking Using Downlink Data Reception and Motion Sensing Information

Abstract:

This disclosure relates to performing receive beam tracking using motion sensing information in a cellular communication system. A wireless device and a cellular base station may establish a cellular link. A receive beam configuration may be selected for the cellular link. A downlink data beam may be received using the selected receive beam configuration. A possible modification to the receive beam configuration may be selected based at least in part on motion sensing information for the wireless device. It may be determined whether the possible modification to the receive beam configuration improves downlink data beam reception. It may be determined whether to modify the receive beam configuration for the cellular link in accordance with the possible modification to the receive beam configuration, for example based on whether the possible modification to the receive beam configuration improves downlink data beam reception.
