Apparatuses and systems for providing multiple structures to enable flexibility of a multiple multiple transmission and reception point ultra-reliable low-latency communication (M-TRP URLLC) operation and reduce measurement effort and power consumption from a transceiving apparatus such as a UE are provided. The techniques disclosed here feature a transceiving apparatus including a transceiver and circuitry. The transceiver, in operation, receives signals from multiple transmission and reception points (M-TRPs) in a network on at least physical downlink shared channels (PDSCHs). The circuitry, in operation, performs beam failure recovery (BFR) by evaluating beam failure detection (BFD) and candidate new beam detection (CBD) for the signals from at least a first one of the M-TRPs. The signals from the first one of the M-TRPs comprise signals received on a physical downlink control channel (PDCCH), and the circuitry determines to skip evaluation of one or both of the BFD and the CBD for one or more additional ones of the M-TRPs in response to one or more conditions.
