Abstract: A Hybrid Automatic Repeat reQuest ACKnowledgement (HARQ-ACK) codebook construction method and transmission method, and a device, are provided. The HARQ-ACK codebook construction method includes: obtaining a time domain feedback record set, where each time domain feedback record in the time domain feedback record set includes a time domain resource assignment record and an equivalent feedback time offset corresponding to the time domain resource assignment record, and the equivalent feedback time offset is a feedback time offset value actually applied when a HARQ-ACK for the time domain resource assignment record corresponding to the equivalent feedback time offset is fed back in an uplink slot; dividing the time domain feedback record set into subsets based on equivalent feedback time offset(s), where each equivalent feedback time offset corresponds to one subset; and constructing a HARQ-ACK codebook based on the subsets obtained through division, to perform feedback in the uplink slot.

Abstract: A HARQ ACK feedback method and apparatus, a terminal, and a storage medium are provided. The HARQ ACK feedback method in embodiments of this application includes: determining, by a terminal, a candidate physical downlink shared channel PDSCH reception occasion set based on a slot timing set corresponding to an actual HARQ ACK feedback unit, where in the slot timing set, each element corresponds to one first slot set and each element corresponds to a different first slot set, where the first slot set comprises at least two consecutive slot units; and determining, by a terminal, a HARQ ACK feedback codebook based on the candidate PDSCH reception occasion set.

Abstract: Embodiments of the present application discloses an information indicating method, a device and a system. The method includes: sending a physical uplink shared channel (PUSCH), wherein the PUSCH bears uplink control information (UCI), the UCI is used to indicate at least one of the following: remaining MCOT information which is used to indicate a remaining maximum channel occupancy time (MCOT) of a channel occupancy time (COT) within which a user equipment (UE) performs uplink transmission, or a target time period. The target time period includes: a time period for allowing a network device to transmit downlink data within COT within which uplink transmission is performed.

Abstract: Embodiments of this disclosure disclose a method for sharing a channel occupancy time and a device. The method includes: determining uplink control information UCI, where the UCI includes first indication information, the first indication information is used to enable a network device to determine related information about downlink transmission in a target time period, a terminal device shares a target channel occupancy time COT in the target time period with the network device, and the target COT is obtained by the terminal device based on listen before talk LBT; and transmitting the UCI.
