1. A terminal comprising:
a receiver that monitors, in a connected mode, a Physical Downlink Control CHannel (PDCCH) for at least one of a system information and a paging; and
a processor that, when a control resource set including the PDCCH is a control resource set with index 0, assumes a Quasi-Co-Location (QCL) relation of a DeModulation Reference Signal (DMRS) antenna port for the PDCCH by a first operation and, when the control resource set is not the control resource set with index 0, assumes a QCL relation of the DMRS antenna port by a second operation that is different from the first operation,
wherein the first operation is an operation that assumes a downlink reference signal notified by a Medium Access Control Control Element (MAC CE) and the DMRS antenna port have a QCL relation, or an operation that assumes a Synchronization Signal/Physical Broadcast Channel (SS/PBCH) block corresponding to a Physical Random Access Channel (PRACH) in a most recent random access procedure and the DMRS antenna port has a QCL relation,
the second opertaion is an operation that assumes a downlink reference signal indicated by a Transmission Configuration Indicator (TCI) state notified by a higher layer signaling and the DMRS antenna port have a QCL relation, and
the processor, when a list of a plurality of TCI states each corresponding to different Transmission and Reception Points (TRPs) is notified by the higher layer signaling, assumes that a downlink reference signal indicated by a TCI state activated by a MAC CE among the list and the DMRS antenna port have a QCL relation.
