Abstract:
Apparatus and method for beam failure recovery (BFR) are proposed. The network node may allocate channel state information-reference signal (CSI) configuration for the user equipment (UE). The CSI configuration may comprise at least one CSI-reference signal (CSI-RS) associated with a serving transmission configuration indication (TCI) for the UE. In addition, the network node may transmit the CSI configuration to the UE. The UE may perform BFD procedure to determine whether a beam failure happens and transmit a beam failure recovery (BFR) request to the network node when the beam failure happens. In addition, the UE may perform operations based on the CSI-RS associated with the serving TCI when the UE receives a response from the network node for the BFR request.
