Patent ID: 11245496

Abstract:
This application provides methods and apparatuses for sending a HARQ-ACK feedback codebook. One example method includes detecting DCI in a plurality of time units corresponding to at least one carrier, where a type of the DCI is a first DCI type or a second DCI type, where the first DCI is used to indicate to feed back CBG-level HARQ-ACK information for data scheduled by the first DCI, and where the second DCI is used to indicate to feed back TB-level HARQ-ACK information for data scheduled by the second DCI. A HARQ-ACK feedback codebook is then sent to a network device, where the codebook includes HARQ-ACK information of at least one piece of data scheduled by the DCI, and the HARQ-ACK feedback codebook is determined according to the type of the DCI and a type of the HARQ-ACK feedback codebook.
