Title:
METHOD FOR TRANSMITTING AND RECEIVING HARQ-ACK INFORMATION IN WIRELESS COMMUNICATION SYSTEM AND DEVICE FOR SAME
Document Type and Number:
WIPO Patent Application WO/2021/010705
Kind Code:
A1
Abstract:
Disclosed in the present invention are a method for transmitting and receiving HARQ-ACK information in a wireless communication system and a device for same. Specifically, a method for a UE to report HARQ-ACK information in a wireless communication system includes the steps of: transmitting a preamble for random access; receiving a response message for the random access corresponding to the preamble, wherein a radio remote control (RRC) connection is established on the basis of the preamble and the response message; receiving a plurality of pieces of downlink control information (DCI) through a physical downlink control channel (PDCCH), wherein control resource sets associated with the PDCCH, through which the pieces of DCI are received, correspond to different control resource set groups; receiving, in a slot n, a physical downlink shared channel (PDSCH) scheduled by means of each piece of DCI; and transmitting the HARQ-ACK information, corresponding to the PDSCH, in a slot n+k through a physical uplink control channel (PUCCH), wherein k is the number of slots, the resource of the PUCCH is determined on the basis of specific DCI among the plurality of pieces of DCI, and the specific DCI is determined on the basis of i) an index of a monitoring occasion pertaining to the PDCCH, (ii) a cell index, and (iii) the index of each control resource set group.
