Claim of US Patent No. 11,071,160


1. A method for wireless communications by a user equipment (UE), comprising:signaling information to a base station (BS) that the UE is seeking recovery of a beamformed link between the BS and the UE; and
participating in recovery of the beamformed link in accordance with the information, wherein recovery of the beamformed link comprises performing a beam sweep sequence to re-establish the beamformed link between the BS and the UE, wherein:performing the beam sweep sequence comprises:transmitting signaling to the BS for a single special beam recovery sequence or multiple sequences; and
using the special beam recovery sequence or the multiple sequences to perform the beam sweep sequence to re-establish the beamformed link between the BS and the UE.
