Title:
METHOD AND APPARATUS FOR DETERMINING UPLINK CONTROL CHANNEL AND SIGNAL RESOURCE IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/025502
Kind Code:
A1
Abstract:
A method performed by a terminal in a wireless communication system includes: receiving at least one downlink control information (DCI) from a base station; determining a physical uplink control channel (PUCCH) resource based on the at least one DCI; and transmitting a PUCCH including hybrid automatic repeat request acknowledgement (HARQ-ACK) information to the base station based on the determined PUCCH resource, wherein the determining of the PUCCH resource comprises: in case that a physical downlink shared channel (PDSCH)-to-HARQ feedback timing indicator field is present in the at least one DCI, determining the PUCCH resource based on information in the PDSCH-to-HARQ feedback timing indicator field in the at least one DCI; and in case that the PDSCH-to-HARQ feedback timing indicator field is not present in the at least one DCI, determining the PUCCH resource based on an radio resource control (RRC) signaling received from the base station.
