Title:
HYBRID AUTOMATIC REPEAT REQUEST FEEDBACK METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/032005
Kind Code:
A1
Abstract:
Disclosed in the present application are a hybrid automatic repeat request feedback method and device; a HARQ-ACK codebook comprises HARQ-ACK information of M PDSCH, the M PDSCH all being scheduled by a first type PDCCH, and the first type PDCCH being used for activating an SPS configuration; the order of the HARQ-ACK information of the M PDSCH in the HARQ-ACK codebook is sorted according to at least one parameter value amongst the respective cell index, the BWP index, the SPS configuration index, and the PDSCH transmission time of the M PDSCH. The embodiments of the present application also comprise a hybrid automatic repeat request feedback method involving a second type PDCCH used for SPS release and a third type PDCCH used for dynamic configuration. The present application also comprises a terminal device and a network device using said method. The present invention solves the problem of how to generate a HARQ-ACK codebook when there are multiple PDSCH under an SPS configuration.
