Title:
METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING SIGNAL IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/091258
Kind Code:
A1
Abstract:
A user equipment according to an embodiment of the present invention: receives DCI via a PDCCH; and transmits a HARQ-ACK report, wherein, on the basis of the DCI indicating the HARQ-ACK report based on a specific type codebook for transmitting ACKs/NACKs for all HARQ processes of serving cells on a one-shot basis and the user equipment being configured to report each NDI bit via the HARQ-ACK report based on the specific type codebook, even though spatial bundling has been configured on the user equipment, the user equipment may transmit the HARQ-ACK report based on the specific type codebook without the spatial bundling.
