Title:
METHOD, USER EQUIPMENT, PROCESSING DEVICE, AND STORAGE MEDIUM FOR TRANSMITTING HARQ-ACK INFORMATION, AND METHOD AND BASE STATION FOR RECEIVING HARQ-ACK INFORMATION
Document Type and Number:
WIPO Patent Application WO/2023/055048
Kind Code:
A1
Abstract:
The UE may: on the basis that transmission of first HARQ-ACK information for PDSCH reception based on an SPS configuration including information about maximum HARQ deferral range K1_def,max overlaps a downlink symbol in a first slot, determine, as a second slot, a slot to which the transmission of the first HARQ-ACK information is deferred, among slots which have, as a time difference between the slots and the first slot, a value equal to or less than K1_def,max; and on the basis that repetition factor R is configured in a PUCCH resource for the transmission of the first HARQ-ACK information in the second slot, and that a difference between the first slot and a slot of the last repetition among R repetitions of PUCCH transmission for the transmission of the first HARQ-ACK information based on the PUCCH resource is equal to or less than R+K1_def,max, perform HARQ deferral so that the transmission of the first HARQ-ACK information is deferred to the second slot.
