Abstract: A first uplink channel is obtained to carry joint information of second uplink control information carried on a second channel and third uplink control information carried on a third uplink channel. In response to the first and third uplink channels meeting a first condition, the joint information is sent on the first uplink channel. Otherwise, the third uplink control information is sent on the third uplink channel. The first condition includes at least one of: (i) a distance between ending symbols on the first and third uplink channels is less than or equal to a first threshold, (ii) a distance between starting symbols on the first and third uplink channels is less than or equal to a second threshold, or (iii) a difference between coding rates of the first and third uplink channels is less than or equal to a third threshold.

Abstract: This application discloses that a terminal device determines at least one target time parameter set based on N time parameter sets, where time unit lengths corresponding to at least two of the N time parameter sets are different; determines M target times based on a first time and the at least one target time parameter set, generates a codebook based on response information corresponding to downlink information received at at least one of the M target times, and sends the codebook to a network device at the first time. Correspondingly, the network device determines, based on the response information included in the codebook, whether the downlink information corresponding to the response information is successfully transmitted. Therefore, when the time unit lengths corresponding to the at least two of the N time parameter sets are different, the network device and the terminal device have a consistent understanding of the codebook.

Abstract: This application provides a feedback information transmission method and an apparatus. The method includes a terminal device that receives indication information from a network device. The indication information indicates to generate a semi-static codebook. The terminal device detects a first physical downlink shared channel (PDSCH) at M candidate receiving positions in a first time unit. The first PDSCH is a semi-persistent scheduling (SPS) PDSCH or a grant-free PDSCH, and M is a positive integer. The terminal device determines, based on a detection result of the first PDSCH, whether to send first feedback information to the network device. The first feedback information includes acknowledgement (ACK) information or negative acknowledgement (NACK) information indicating whether the first PDSCH detected at the M candidate receiving positions is correctly decoded.

Abstract: This application provides a method for transmitting hybrid automatic repeat request HARQ feedback information and a communications apparatus. A terminal device receives downlink data channels. Each of the downlink data channels has a corresponding transmission parameter group, and at least two downlink data channels correspond to different transmission parameter groups. The terminal device determines a first transmission resource based on first information including the transmission parameter groups, and sends, on the first transmission resource, HARQ feedback information corresponding to the downlink data channels, so that a plurality of pieces of HARQ feedback information can be smoothly fed back. This helps improve service transmission reliability.

Abstract: Embodiments of this application provide slot format configuration method and device. According to the method, a network device determines a slot format index for performing uplink-downlink transmission with a terminal device. The slot format index corresponds to a row in a slot format information table, and each row in the slot format information table includes positions of uplink symbols, positions of downlink symbols, and positions of unknown symbols in a slot. The network device sends the slot format index to the terminal device. The terminal device determines a slot format for the uplink-downlink transmission from the slot format information table based on the slot format index. The uplink-downlink slot configuration method provided in the embodiments of this application may satisfy specific requirements of low-latency and high-reliability communication scenarios.
