    Abstract: A terminal according to one aspect of the present disclosure includes: a receiving section that receives configuration information including a configuration related to a transmission configuration indication (TCI) state to be applied to a plurality of types of channels and indication of the TCI state, a TCI field codepoint included in the indication being associated with a plurality of the TCI states; and a control section that determines, based on information related to application initiation timing of the TCI state included in the configuration information and the indication, the application initiation timing of the TCI state. According to one aspect of the present disclosure, it is possible to appropriately recognize a TCI state.

    Abstract: A terminal according to one aspect of the present disclosure includes a receiving section that receives a downlink control channel, and a control section that judges, based on the presence or absence of configuration or support of scheduling of a plurality of downlink shared channels in a plurality of transmission/reception points using downlink control information provided by the downlink control channel, at least one of a transmission configuration indication (TCI state) indicated by the downlink control information and a TCI state corresponding to a downlink shared channel scheduled by the downlink control information.

    Abstract: A terminal includes a reception unit configured to receive downlink data scheduled by SPS (Semi-Persistent Scheduling); a control unit configured to perform postponement of HARQ-ACK (Hybrid Automatic Repeat reQuest-ACKnowledgement) corresponding to the downlink data, a maximum postponement period being configured to the postponement; and a transmission unit configured to transmit an uplink control channel that carries uplink control information including the HARQ-ACK via a resource determined based on the postponement of the HARQ-ACK. The control unit performs carrier switching of the uplink control channel as necessary, and determines whether the postponement of the HARQ-ACK exceeds the maximum postponement period, based on a subcarrier spacing of: a cell before performing the carrier switching; a cell after performing the carrier switching; or a cell indicated by a semi-static cell pattern.

    Abstract: A terminal includes a reception unit configured to receive, from a base station, a configuration concerning semi persistent scheduling (SPS) and a physical downlink shared channel (PDSCH) according to the SPS; a control unit configured to determine hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback information corresponding to the PDSCH according to the SPS, configure a HARQ-ACK codebook concerning the feedback information, and determine a bit with respect to the feedback information by applying the codebook; and a transmission unit configured to transmit the feedback information to the base station. The control unit is configured to configure the codebook based on the configuration concerning the SPS.

    Abstract: A terminal includes a receiver configured to receive data according to SPS (Semi Persistent Scheduling); a controller configured to postpone transmission of a first channel for transmitting feedback information with respect to the data until a valid uplink resource is determined, and determine a resource for transmitting the first channel in a case where the postponed first channel is overlapped in a time domain with a second channel, the second channel being another uplink channel; and a transmitter configured to transmit the feedback information to a base station in the determined resource.

    Abstract: A terminal according to one aspect of the present disclosure includes a transmitting section that transmits a plurality of repetitions of a physical random access channel by using a plurality of different beams, and a control section that determines a reference beam corresponding to one of the plurality of different beams and that determines, on the basis of reception of a response to the physical random access channel, a subsequent uplink beam, the reception using the reference beam. According to one aspect of the present disclosure, it is possible to improve coverage in a random access procedure.
