Document Type and Number:
WIPO Patent Application WO/2023/011637
Kind Code:
A1
Abstract:
A method performed by a UE is provided. The method includes receiving a first DCI format for scheduling at least one HARQ-ACK codebook in at least one first PUCCH in at least one first slot; receiving a second DCI format in a second slot, the second DCI format (i) for scheduling a retransmission of the HARQ-ACK codebook in a second PUCCH and (ii) indicating a first slot offset; and transmitting the first HARQ-ACK codebook scheduled in one of the at least one first slot via the second PUCCH. If the first slot offset is a positive value, the first slot is determined by counting backward a number of slots indicated by the first slot offset from the second slot. If the first slot offset is a negative value, the first slot is determined by counting forward the number of slots indicated by the first slot offset from the second slot.
