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： Efficient frequency hopping is performed in a case that repeated transmission is enabled in a slot. In a case that a configuration related to inter-slot frequency hopping is configured using RRC signaling, and a higher layer parameter related to a plurality of repeated transmissions in one slot is configured, frequency hopping is applied based on the current number of transmissions of transport blocks. On the other hand, in a case that the configuration related to the inter-slot frequency hopping is configured using the RRC signaling, and the higher layer parameter related to a plurality of repeated transmissions in one slot is not configured, frequency hopping is applied based on a current slot number.

摘要： In a case that an uplink timing alignment timer expires, Type 1 configured uplink grants configured in all serving cells belonging to a TAG associated with the uplink timing alignment timer are suspended. A random access response including a timing advance command configured for the TAG is received. In a case that a random access preamble included in the random access response is not a contention based random access preamble, or in a case that the random access response includes the contention based random access preamble and includes information indicating successful random access contention resolution, and the timing alignment timer associated with the TAG is not running, the Type 1 configured uplink grants configured and suspended in the all serving cells belonging to the TAG are re-initialized.

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： In a case of configuring multiple configured grants, signal detection in a base station apparatus is efficiently performed. For configured grant scheduling, by configuring a plurality of time offset values, multiple transmission opportunities are generated. To each of the transmission opportunities, a slot retransmission is applied. In a case that multiple transmission patterns are generated due to the plurality of time offsets, transmission is performed by using a transmission pattern, among the multiple transmission patterns, that causes the number of remaining retransmissions to increase.
