Abstract
A user equipment (UE) may establish communication with a plurality of transmission reception points (TRPs) and determine one or more beam failures associated with a first or second TRP based on reference signals received from the first and second TRPs. The UE may then transmit a scheduling request requesting resources for indicating the beam failures associated with the first TRP or second TRPs. Upon receiving a response to the scheduling request allocating resources, the UE may then transmit, using allocated resources, a beam failure indication of the first one or more beam failures associated with the first TRP or second TRP. After receiving a beam failure response from the first or second TRP, the UE may then communicate with the first TRP and the second TRP using one or more new beams based on the beam failure indication and the beam failure response.
