20220006506 · 2022-01-06 ·

Various embodiments disclosed herein provide for a beam recovery when there has been a partial control channel failure. Transient obstructions, and other interference effects can cause the failure of a beam pair link which can comprise a transmit beam and a receive beam associated with respective antennas on a transmitter and receiver. A group of control channels (downlink control channels) (configured as a control resource set “CORESET”) on a group of beam pair links can be associated with a group of uplink control resources (Physical Uplink Control Channel resources). When a subset of the CORESET group fails, the user equipment (UE) device can find another PUCCH that is associated with a working CORESET to send an indication to the network about the failure. When the network receives the indication, the network can switch the failed CORESET to a new beam pair link.
