  • Publication number: 20240163869
    Abstract: A user equipment (UE) is described. The UE may comprise high-layer processing circuitry configured to acquire a RRC parameter and transmission circuitry configured to transmit a PUSCH in multiple slots. The RRC parameter may indicate that the multiple slots are determined according to slots which are available for transmission(s) of the PUSCH. If the RRC parameter is not provided, processing time for canceling a transmission of the PUSCH may be required to be shorter than or equal to a first length. If the RRC parameter is provided, the processing time for canceling a transmission of the PUSCH may be required to be shorter than or equal to a second length. The second length is longer than the first length.

  • Publication number: 20240155610
    Abstract: A terminal apparatus includes a reception circuitry that receives a PDCCH including a DCI format; and a transmission circuitry that transmits a PUCCH. The DCI format indicates transmission of the PUCCH. In a case that a first higher layer parameter NrofSlots indicating the number of repetitions is configured for a PUCCH format corresponding to the transmission of the PUCCH, the number of repetitions of the transmission of the PUCCH is determined based on the first higher layer parameter. In a case that the number of repetitions per transmission of the PUCCH is indicated to be valid for the transmission of the PUCCH based on a second higher layer parameter, the number of repetitions of the transmission of the PUCCH is determined based on a value set in a PUCCH-RepetitionFactor field for the transmission of the PUCCH, included in the DCI format.

  • Publication number: 20240137935
    Abstract: A terminal apparatus includes a reception circuitry that receives a PDCCH where a DCI format is mapped; and a transmission circuitry that transmits a PUCCH corresponding to a PUCCH resource indicated based on the DCI format. A first higher layer parameter is configured for a PUCCH format corresponding to the PUCCH. In a case that a second higher layer parameter is configured for the PUCCH resource, the number of repetitions of the PUCCH is a value of the second higher layer parameter, and in a case that the second higher layer parameter is not configured, the number of repetitions of the PUCCH is a value of the first higher layer parameter.

  • Publication number: 20240107583
    Abstract: Terminal device attempts to initiate a COT-u after the channel is sensed to be idle and transmit a configured grant PUSCH. A start of a time domain resource of the configured grant PUSCH is aligned with the start of the FFP-u. In a case that the FFP-u does not overlap with an IP-g of an FFP-g, the COT-u is initiated and the configured grant PUSCH is transmitted.

  • Publication number: 20240098777
    Abstract: Terminal device attempts to transmit a PUSCH scheduled by a DCI format after the channel is sensed to be idle. When the start of the PUSCH is not aligned with an FFP-u, in a case that the channel access mode is configured to as semi-static, the terminal device does not initiate a COT, regardless of indication by a ChannelAccess-CPext field in the DCI format.
