摘要： A terminal apparatus for communicating with a base station apparatus, the terminal apparatus including: a radio receiving unit configured to receive a CSI reference signal; a controller configured to calculate channel state information (CSI); and a transmitter configured to transmit the CSI, wherein the controller calculates the CSI, based on an RRC parameter related to the number of repetitions in a case that a transport block error rate to be used in calculating the CSI is configured by a higher layer processing unit, and calculates the CSI that is not dependent on the RRC parameter related to the number of repetitions in a case that the transport block error rate to be used in calculating the CSI is not configured by the higher layer processing unit.

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： A terminal apparatus includes a control information detection unit configured to detect first and second DCI, and a transmitter configured to perform UL data transmission based on the first DCI or cancel a resource allocated in the second DCI. A UL grant using the first DCI is detected, when performing UL data transmission based on the UL grant, after the data transmission, a first timer for a corresponding HARQ process is started and a second timer is stopped, and when the first timer expires, the second timer for a HARQ process is started. When cancellation of the UL data transmission using the second DCI is detected, at a timing for the data transmission canceled, the second timer is restarted in a case that the first timer expires and the second timer is running, and the second timer is started in a case that the second timer is not running.

摘要： A terminal apparatus includes a transmitter configured to transmit PUSCH data and a receiver configured to receive RRC information. The transmitter transmits the PUSCH data by using a resource associated with an HARQ process ID determined by symbol information for transmission of the PUSCH data, a period, and the number of HARQ processes. In a case that the receiver receives no response to the transmission of the PUSCH data with the HARQ process ID after the transmission of the PUSCH data is performed and before a timer included in the RRC information expires, the transmitter transmits new PUSCH data by using the resource associated with the HARQ process ID determined by the symbol information for the transmission of the PUSCH data, the period, and the number of HARQ processes.

摘要： A terminal apparatus and a method for communicating with a base station apparatus are provided. The method includes receiving Radio Resource Control (RRC) signaling and a first DCI format addressed to a Cell-Radio Network Temporary Identifier (C-RNTI); determining a first priority of a first uplink grant based on a priority field in the RRC signaling; and transmitting a first Physical Uplink Shared Channel (PUSCH) scheduled by the first uplink grant and a second PUSCH scheduled by a second uplink grant. The first uplink grant is a configured uplink grant notified by the RRC signaling. The second uplink grant is notified by the first DCI format.
