  • Publication number: 20240080140
    Abstract: A terminal comprising: a control unit that performs feedback control to transmit two or more acknowledgments over one physical uplink control channel, wherein the control unit performs, when the two or more acknowledgments include a first acknowledgment with a first priority and a second acknowledgment with a second priority different from the first priority, the feedback control using a resource related to a specific acknowledgment of either the first acknowledgment or the second acknowledgment.

  • Publication number: 20240049195
    Abstract: A terminal includes: a reception unit configured to receive a block including a synchronization signal and a broadcast channel, a control channel carrying control information, and a shared channel carrying system information by applying single beamforming; and a control unit configured to perform an initial access, based on the system information. The block and one or both of the control channel and the shared channel are frequency-multiplexed, and the control channel and the shared channel are time-multiplexed.

  • Publication number: 20240032013
    Abstract: A terminal includes a reception unit configured to receive, from a base station, a configuration concerning semi persistent scheduling (SPS) and a physical downlink shared channel (PDSCH) according to the SPS; a control unit configured to determine hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback information corresponding to the PDSCH according to the SPS, configure a HARQ-ACK codebook concerning the feedback information, and determine a bit with respect to the feedback information by applying the codebook; and a transmission unit configured to transmit the feedback information to the base station. The control unit is configured to configure the codebook based on the configuration concerning the SPS.

  • Publication number: 20240023081
    Abstract: A terminal includes: a reception unit configured to receive data according to SPS (Semi persistent scheduling) from a base station; a control unit configured to determine HARQ-ACK (Hybrid automatic repeat request Acknowledgement) feedback information corresponding to the data, wherein transmission of the HARQ-ACK feedback information is required to be postponed until a valid uplink resource is found, configure a HARQ-ACK codebook related to the feedback information, and determine bits of the feedback information by applying the codebook; and a transmission unit configured to transmit the feedback information to the base station. The control unit configures the codebook based on priorities configured to the bits.

  • Publication number: 20240015750
    Abstract: A terminal includes: a control unit that multiplexes uplink control information on an uplink shared channel; and a communication unit that transmits an uplink signal using the uplink shared channel on which the uplink control information is multiplexed. The control unit multiplies a number of bits constituting the uplink control information by a coefficient in a rate matching of the uplink control information. The control unit applies, as a range of coefficient, a specific range corresponding to a combination of a priority of the uplink control information and a priority of the uplink shared channel.

  • Publication number: 20230397214
    Abstract: A terminal comprises: a control unit that multiplexes two or more uplink control information having mutually different priorities on an uplink control channel; and a communication unit that transmits an uplink signal using the uplink control channel on which the two or more uplink control information are multiplexed; wherein the control unit determines a number of resource blocks related to the uplink control channel in a separate coding of the two or more uplink control information.

  • Publication number: 20230379098
    Abstract: A terminal according to an aspect of the present disclosure includes: a receiving section configured to receive information regarding skipping of a hybrid automatic repeat request acknowledgement (HARQ-ACK) for a semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH) that is not transmitted; and a control section configured to control HARQ-ACK bundling for a SPS PDSCH that is transmitted, on the basis of information included in downlink control information (DCI). According to one aspect of the present disclosure, it is possible to suitably transmit and receive a semi-persistent scheduling PDSCH and a HARQ-ACK corresponding to the PDSCH.

  • Publication number: 20230379898
    Abstract: A terminal includes a receiver configured to receive data according to SPS (Semi Persistent Scheduling); a controller configured to postpone transmission of a first channel for transmitting feedback information with respect to the data until a valid uplink resource is determined, and determine a resource for transmitting the first channel in a case where the postponed first channel is overlapped in a time domain with a second channel, the second channel being another uplink channel; and a transmitter configured to transmit the feedback information to a base station in the determined resource.

  • Publication number: 20230276436
    Abstract: Embodiments of the present disclosure relate to the field of wireless communication technologies, and a communication method, a user equipment, a network device, and a computer storage medium are disclosed. The communication method includes: determining a number of repetitions of a physical uplink shared channel (PUSCH), wherein the PUSCH is a PUSCH of Msg3 in a random access procedure and the number of repetitions is a positive integer; and then transmitting the PUSCH to the network device with the number of repetitions. By using the communication method provided by an embodiment of the present disclosure, the user equipment may determine a number of repetitions for a Msg3 PUSCH (a PUSCH of Msg3), thus providing a solution for supporting the repetitions of Msg3 PUSCH and solving a critical technical problem of uplink coverage enhancement, and improving the uplink coverage range of the Msg3 PUSCH greatly.
