    Abstract: The present invention is designed so that uplink control information such as delivery acknowledgment signals can be transmitted properly, even when UL/DL configurations are changed, in a communication system that is configured to use listening. According to one aspect of the present invention, a user terminal has a receiving section that receives downlink control information and downlink data, a transmission section that transmits a delivery acknowledgment signal in response to the downlink data, and a control section that controls transmission of the delivery acknowledgment signal based on a result of UL listening which is executed before transmission of the delivery acknowledgment signal, and based on information that is contained in the downlink control information and/or timing that is configured in advance on a per DL burst basis.

    Abstract: A terminal according to one aspect of the present disclosure includes: a control section that determines a transmission configuration indication (TCI) state to apply to a physical downlink shared channel (PDSCH), based on at least one of whether Doppler pre-compensation is applied to the PDSCH, a frequency range, a magnitude relation between an offset from reception of downlink control information (DCI) for scheduling the PDSCH to reception of the PDSCH and a threshold value, and the DCI; and a receiving section that receives the PDSCH by using the TCI state. According to one aspect of the present disclosure, operation related to a TCI state/default TCI state can be appropriately controlled.

    Abstract: A terminal according to one aspect of the present disclosure includes a receiving section that receives information indicating two transmission configuration indication (TCI) states for a physical downlink shared channel (PDSCH), and a control section that does not apply a first quasi co-location (QCL) parameter in a plurality of QCL parameters included in a specific TCI state in the two TCI states to reception of the PDSCH, and applies a second QCL parameter other than the first QCL parameter in the plurality of QCL parameters to the reception of the PDSCH. According to one aspect of the present disclosure, downlink signals from a plurality of transmission points can be appropriately received.

    Abstract: A user terminal according to one aspect of the present disclosure includes a transmitting section that transmits a demodulation reference signal (DMRS) based on π/2-BPSK modulation in uplink transmission of at least one of an uplink shared channel and an uplink control channel, before radio resource control (RRC) connection establishment, and a control section that performs the RRC connection establishment, based on the uplink transmission. According to an aspect of the present disclosure, it is possible to appropriately perform uplink transmission employing π/2-BPSK modulation.

    Abstract: To properly control UL transmissions of A/N in response to a plurality of DL transmissions with different requirements and the like, one aspect of a user terminal in the present disclosure has a transmitting section that transmits a first delivery acknowledgement signal (A/N) in response to a first PDSCH and a second A/N in response to a second PDSCH transmitted later than the first PDSCH, and a control section that controls to transmit at least one of the first A/N and the second A/N, using one of an uplink control channel configured for the first A/N and another uplink control channel configured for the second A/N, in a case where transmission timing of the first A/N overlaps transmission timing of the second A/N.
