COORDINATED BEAM REFINMENT AND COORDINATED BEAM FAILURE RECOVERY

Abstract:

Wireless communications systems and methods related to coordinated beam refinement and coordinated beam failure recovery (BFR) in a wireless communication network are provided. A first wireless communication device communicates, with a second wireless communication device of a group of wireless communication devices, a communication signal using a first beam characteristic. The first wireless communication device receives, from the second wireless communication device, at least one of beam feedback information or a beam change request. The first wireless communication device transmits, to the group of wireless communication devices in response to the at least one of the beam feedback information or the beam change request, a beam configuration indicating a second beam characteristic to be used by the group of wireless communication devices for communicating with the first wireless communication device, the second beam characteristic being different from the first beam characteristic.
