- First monitoring control the user terminal continues to monitor a specific DCI (for example, at least one DCI (PDCCH) of (1) to (3) described later) during the BFR procedure. That is, the user terminal continues to monitor a specific DCI monitored before the start of the BFR procedure regardless of the start and / or success of the BFR procedure.

- the beam failure instance notification may be notified in the MAC layer in the PHY layer in a predetermined cycle.
- the beam failure instance notification may include information regarding the presence / absence of beam failure and / or information regarding the presence / absence of a new candidate beam.
- the MAC layer of the user terminal may trigger transmission of a BFR request when the value of the predetermined counter becomes equal to or exceeds a predetermined threshold. For example, in FIG. 2, at time T2, the beam failure instance counter becomes greater than or equal to a predetermined threshold value, so the MAC layer may notify the PHY layer of a BFR request transmission instruction (trigger information). The beam failure may be detected by the MAC layer when the BFR request is triggered.
