Document Type and Number:
WIPO Patent Application WO/2019/072074
Kind Code:
A1
Abstract:
Provided in the present application are a HARQ-ACK feedback codebook sending method, an apparatus and a device. The method comprises a terminal detecting DCI on multiple time units of at least one carrier, a type of the DCI being a first DCI type or a second DCI type, first DCI being used to indicate feedback of CBG-level HARQ-ACK information for first DCI scheduled data, and second DCI being used to indicate feedback of TB-level HARQ-ACK information for second DCI scheduled data; the terminal sending a HARQ-ACK feedback codebook to a network device, the codebook comprising HARQ-ACK information of at least one DCI scheduled data; and the HARQ-ACK feedback codebook being determined by a DCI type and a HARQ-ACK feedback codebook type. The present invention can solve the problem of how to perform HARQ-ACK feedback codebook transmission in a HARQ-ACK multiplexing scenario.
