Title:
APPARATUS AND METHOD FOR BEAM FAILURE RECOVERY
Document Type and Number:
WIPO Patent Application WO/2020/048443
Kind Code:
A1
Abstract:
Provided herein are apparatus and method for beam failure recovery. The disclosure provides an apparatus for a user equipment (UE), comprising: a radio frequency (RF) interface to receive beam failure recovery request (BFRQ) resource configuration information; and processor circuitry coupled with the RF interface, wherein the processor circuitry is to: determine a physical uplink control channel (PUCCH) resource unit for a BFRQ of a beam failure recovery (BFR) procedure based on the BFRQ resource configuration information received from the RF interface, wherein the BFRQ is to only indicate that beam failure happens; and cause transmission of the BFRQ via the PUCCH resource unit. Other embodiments may also be disclosed and claimed.
