Abstract: This application discloses a method for waveform switching, a device, and a chip. The method includes: The terminal receives a first downlink control information (DCI) from a network device, where the first DCI is used to schedule physical channels of a plurality of cells; and the terminal uses pre-configured waveforms of the physical channels of the plurality of cells, where when the first DCI is used to schedule the physical channels of the plurality of cells, the terminal does not support dynamic waveform switching.

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: 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.
