  • Patent number: 11265912
    Abstract: 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.

  • Publication number: 20220060215
    Abstract: 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.

  • Publication number: 20220022208
    Abstract: Efficient transmission is performed in a case that an allocation periodicity is shorter than an interval based on repeated transmission. For configuration grant scheduling, in a case that the allocation periodicity is shorter than the interval based on the repeated transmission, a port number for a DMRS is determined according to the number of repetitions to allow a base station apparatus to determine which periodicity corresponds to the start of the transmission. Thus, by detecting the port number for the DMRS, the base station apparatus can recognize the start or the end of the transmission by the terminal apparatus.

  • Publication number: 20220014235
    Abstract: 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.

  • Publication number: 20210307017
    Abstract: 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.

  • Patent number: 11115960
    Abstract: 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.
