METHOD AND DEVICE FOR TRANSMITTING AND RECEIVING SIGNALS IN WIRELESS COMMUNICATION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2020/167104

Kind Code:

A1

Abstract:

In a method and device for a wireless communication system according to one embodiment of the present invention, downlink control information (DCI) for downlink data transmission on a primary cell (PCell) is received, a downlink assignment index (DAI) value included in the DCI is 1, the downlink data is received on the basis of the DCI, and hybrid automatic repeat request (HARQ) information about the downlink data is transmitted. In addition, on the basis of a channel state information (CSI) and/or scheduling request (SR) transmission set in a subframe in which the HARQ information is transmitted, (i) the HARQ information and (ii) the CSI and/or the SR are transmitted together in the subframe, and on the basis of multi radio-dual connectivity (MR-DC) being set in a terminal, (i) the HARQ information and (ii) the CSI and/or the SR are transmitted on a resource related to PUCCH format 3.
