Title:
METHOD AND DEVICE FOR TRANSMITTING/RECEIVING HARQ-ACK SIGNAL
Document Type and Number:
WIPO Patent Application WO/2019/168338
Kind Code:
A1
Abstract:
The present invention provides a method for transmitting, by a terminal, a hybrid automatic repeat request-acknowledgement (HARQ-ACK) signal in a wireless communication system. In particular, in the method, at least one first physical downlink shared channel (PDSCH), associated with the HARQ-ACK signal, is received within a first bandwidth part (BWP); downlink control information (DCI) is received to change an activated BWP associated with a downlink signal from the first BWP to a second BWP; at least one second PDSCH associated with the HARQ-ACK signal is received within the second BWP; and the HARQ-ACK signal is transmitted, wherein the HARQ-ACK signal does not include HARQ-ACK information for the at least one first PDSCH.
