Abstract: In order to control communication operations properly in a secondary cell even when a beam failure and/or a BR failure occur in the secondary cell, a user terminal, according to one aspect of the present disclosure, has a control section that controls adjustment of a deactivation timer for a certain secondary cell and/or indication of a beam failure and/or a beam recovery (BR) failure in the certain secondary cell, based on the beam failure and/or a result of BR in the certain secondary cell, and a transmission section that transmits information about the beam failure and/or the BR failure in the certain secondary cell by using another cell.

Abstract: A user terminal includes a receiving section that receives downlink control information including information indicating a first combination of one or more slot formats, and a control section that controls modification of the slot formats determined based on the information indicating the first combination in a case where another downlink control information including a second combination of one or more slot formats is detected on a monitoring occasion with periodicity shorter than a period corresponding to the one or more slot formats, based on the information indicating the second combination. This allows a slot format of each slot to be flexibly controlled.

Abstract: A terminal receives a plurality of SSBs in a frequency band including one frequency range or a plurality of frequency ranges and a different frequency band different from the frequency band. The SSBs are divided into a plurality of synchronization signal groups. The terminal receives the synchronization signal groups transmitted according to a periodicity shorter than a defined transmission periodicity.

Abstract: A terminal receives a radio frame having a second slot pattern to be used in a case in which a modulation system (FTN) different from a modulation system in a case of using a first slot pattern is applied. The terminal applies for the second slot pattern a configuration of an uplink and a downlink according to a time division duplex in the radio frame by using a reference subcarrier spacing same as that for the first slot pattern.

Abstract: The present invention is designed to allow co-presence with other systems, and, furthermore, achieve improved spectral efficiency in cells (for example, unlicensed bands) in which pre-transmission listening is employed. The present invention provides a transmitter that transmits a downlink (DL) signal, a controller that controls DL transmission by applying listening before performing transmission of the DL signal, and a receiver that receives a delivery acknowledgement signal (ACK/NACK) in response to the DL transmission, wherein the controller controls a contention window value to apply to listening based on a number of acknowledgements (ACKs) in response to the DL transmission within a predetermined period, and a number of codewords and/or a number of transport blocks for the DL transmission.
