Abstract: A method of default uplink beam determination after a beam failure recovery (BFR) procedure in a beamforming system is proposed.

The configuration includes spatial relation information that indicates the spatial filter to be used by UE for the corresponding PUCCCH transmission. After BFR procedure is completed and before the first spatial relation information indication for a PUCCH resource is received by UE, a default UE TX beam for the PUCCH resource can be determined based on the UE TX beam used during the BFR procedure, e.g., the UE TX beam used to transmit a beam failure recovery request (BFRQ) during the BFR procedure.

Abstract: A method of beam failure recovery request (BFRQ) transmission is proposed. In a first step of beam failure detection, UE detects a beam failure condition of the original serving beam. In a second step of new candidate beam identification, UE performs measurements for candidate beam selection. In a third step of beam failure recovery request (BFRQ) transmission, UE transmits a BFRQ message to BS upon the triggering condition for BFRQ transmission is satisfied. In a fourth step of monitoring BS response, UE monitors BS response to decide the success or failure of the BFRQ transmission attempt. In one advantageous aspect, the BFRQ transmission is over dedicated contention-free PRACH or PUCCH resources or over contention-based PRACH resources. Furthermore, a beam failure recovery timer is used to oversee the initiation and the termination of the BFRQ transmission.
