摘要： A state managing unit configured to control a prescribed communication resource allocating process and a reception processing unit configured to receive a control element (CE) are included. The prescribed communication resource allocating process is a process of allocating a communication resource at a predetermined time interval, and the state managing unit suspends an uplink grant configured for the prescribed communication resource allocating process in a case that the reception processing unit receives an SCell Activation/Deactivation MAC CE for deactivating a secondary cell, or an sCellDeactivationTimer configured for the secondary cell expires, and the state managing unit reinitializes the uplink grant suspended, in a case that the reception processing unit receives the SCell Activation/Deactivation MAC CE for activating the secondary cell after the state managing unit suspends the uplink grant.

摘要： According to the present invention, transmission is efficiently and repeatedly performed within a slot. The number of repetitions in the slot is calculated using OFDM symbol allocation in a slot notified using a predetermined field during RRC signaling or DCI formatting and the number of divisions in the slot notified by the RRC signaling (or the number of OFDM symbols serving as repetition unit). When the calculated number of repetitions does not satisfy a predetermined condition, repeated transmission is not performed.

摘要： Included are a receiver configured to receive first downlink data mapped to the first component carrier and second downlink data mapped to the second component carrier; and a transmitter configured to transmit a signal for indicating delivery confirmation of the first downlink data and the second downlink data. A timing to transmit the signal for indicating the delivery confirmation is defined by a prescribed number of time slots, and a length of each of the time slots is configured based on a subcarrier spacing of the first component carrier and a subcarrier spacing of the second component carrier.

摘要： To provide a base station apparatus, a terminal apparatus, and a communication method capable of ensuring high reliability and low latency of URLLC. There are included a receiver configured to detect first and second DCI formats and RRC information, and a transmitter capable of data transmission based on any of a first uplink grant to be available via activation by using a radio resource periodicity included in the RRC information and the first DCI format, a second uplink grant to be available via activation by using the radio resource periodicity included in the RRC information and the second DCI format, and a third uplink grant to be available after detection of the second DCI format, wherein multiple DCI formats are detected, the transmitter performs an override, in a case that the third uplink grant overlaps in a time domain with the second uplink grant, and performs an override, in a case that the first uplink grant overlaps in a time domain with the third uplink grant.

摘要： When a plurality of configured uplink grants are set for one serving cell or BWP, competition among resources for transmission thereof may occur, which prevents normal transmission of uplink (UL) data. The present disclosure includes a control unit that performs an uplink (UL) data transmission setting according to an radio resource control (RRC) message from an RRC; and, a transmitting unit that transmits UL data according to the UL data transmission setting; the RRC message includes setting information of a plurality of configured UL grants (CGs), the setting information includes at least a first and a second CGs for each bandwidth part (BWP), the setting information for the plurality of CGs includes setting information of transmission intervals for the first and the second CGs, the control unit sets a plurality of CGs for each BWP according to the setting information of the plurality of CGs for each BWP included in the RRC message, the transmitting unit, when at least a part of the respective transmission intervals of the first and the second CGs overlap, interrupts any one UL data transmission of the first and the second CGs and performs UL data transmission of the other.
