  • Publication number: 20200236570
    Abstract: A user equipment (UE) is configured with at least one bandwidth part (BWP) specific configuration information. The UE receives a configuration information specific to the bandwidth part (BWP). The configuration information configures an initial value of a beam failure detection (BFD) timer and a beam failure indication (BFI) count threshold. The UE starts or re-starts the BFD timer from the initial value when receiving a beam failure indication (BFI) from a lower sublayer, and counts a number of the received BFIs using a BFI counter. The UE resets the BFI counter to zero when receiving a reconfiguration information. The reconfiguration information, that is specific to the BWP, re-configures at least one of the initial value of the BFD timer and the BFI count threshold.
