    Abstract: A base station in a network system includes: a transmission unit configured to transmit a first reference signal to a terminal via a first non-terrestrial communication device; and a reception unit configured to receive information related to a reception timing at the terminal from the terminal. The transmission unit transmits information related to a propagation delay of the first reference signal and information related to the reception timing to LMF (Location Management Function), and the information related to the reception timing is a time difference between a reception timing of the first reference signal and a reception timing of a second reference signal that is transmitted from the base station or from a second base station that is different from the base station via a second non-terrestrial communication device.

    Abstract: A terminal according to one aspect of the present disclosure includes: a receiving section that receives a reference signal associated with a second physical cell ID (PCI) different from a first physical cell ID (PCI) corresponding to a serving cell; and a control section that controls, by using the reference signal, at least one of radio link monitoring (RLM), beam failure detection (BFD), and beam failure recovery (BFR). According to one aspect of the present disclosure, an RS to be used for at least one of the RLM, BFD, and BFR can be appropriately determined.

    Abstract: A terminal according to one aspect of the present disclosure includes a receiving section that receives configuration information related to a control resource set in a downlink bandwidth part, and a control section that determines, based on a plurality of transmission configuration indication (TCI) states corresponding to a specific control resource set based on the configuration information, at least one of a plurality of spatial relations and a plurality of pathloss reference signals to be applied to a plurality of repetition transmissions of a physical uplink control channel (PUCCH). According to one aspect of the present disclosure, it is possible to appropriately control operation related to a default TCI state/spatial relation/pathloss reference signal.

    Abstract: A terminal according to one aspect of the present disclosure includes a receiving section that, when a separate Transmission Configuration Indication (TCI) state is applied to each of a downlink (DL) and an uplink (UL), receives a specific configuration for enabling or disabling initiation of activation of the TCI state of at least one of the UL and the DL by a UE, and a control section that initiates activation of the TCI state. According to one aspect of the present disclosure, an appropriate TCI state can be activated.

    Abstract: A terminal according one aspect of the present disclosure includes: a transmitting section that transmits a random access channel, based on a first downlink control channel; and a control section that assumes that, when detection of downlink control information is performed in response to the transmission of the random access channel, the first downlink control channel and a second downlink control channel providing the downlink control information are quasi-co-located, wherein based on at least one of whether repetition transmission of the first downlink control channel is performed and whether repetition transmission of the second downlink control channel is performed, the control section judges a first downlink control channel and a second downlink control channel being in a quasi-co-location relationship.
