  • 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.

    Abstract: A base station apparatus receives an uplink shared channel and a reference signal, the uplink shared channel including uplink data, an identifier of a terminal apparatus that has transmitted the uplink data, a first CRC generated from the identifier bits, and a second CRC generated from the uplink data bits. In a case that an error is detected based on the first CRC, the base station apparatus transmits a first NACK by using a control signal associated with the reference signal sequence. In a case that an error is detected based on the second CRC, the base station apparatus transmits a second NACK by using a control signal associated with the identifier indicating the terminal apparatus.

  • Patent number: 11026184
    Abstract: To improve throughput in a communication environment in which a large number of terminal apparatuses access, a receiver receives information indicating whether a radio resource allocated by a base station apparatus is a grant free access resource or a scheduled access resource, as well as transmission power control information in the scheduled access resource and transmission power control information in the grant free access resource; and a transmitter configured to transmit a transmission signal to the base station apparatus. In a case of communicating by using the scheduled access resource, a transmission power control is performed based on the first transmission power control information to transmit the transmission signal. In a case of communicating by using the grant-free access resource, the transmission power control is performed based on the second transmission power control information to transmit the transmission signal.

  • Patent number: 11012111
    Abstract: In a case that a large number of terminal apparatuses that are accommodated by contention-based radio communication technologies share a frequency resource, the number of data signals of the terminal apparatus that are non-orthogonally multiplexed in the spatial domain increases. If terminal apparatuses, of which the number exceeds the number of receive antennas or the spreading factor transmit uplink data at the same time, it is tantamount to a presence of terminal apparatuses using the same spreading code, and inter-user interference becomes a problem.

    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.
