Title:
METHOD AND DEVICE FOR TRANSMITTING AND RECEIVING HYBRID AUTOMATIC REPEAT REQUEST ACKNOWLEDGEMENT INFORMATION
Document Type and Number:
WIPO Patent Application WO/2023/204677
Kind Code:
A1
Abstract:
The disclosure relates to a 5th generation (5G) or 6th generation (6G) communication system for supporting a higher data transmission rate. A method and device for transmitting hybrid automatic repeat request acknowledgement (HARQ-ACK) information are provided. The method includes receiving, from a base station (BS), downlink control information (DCI) scheduling one or more multicast physical downlink shared channels (PDSCHs), wherein the DCI includes a downlink assignment indication (DAI) associated with the one or more multicast PDSCHs, receiving, from the BS, the one or more multicast PDSCHs based on the DCI, in case that a number of hybrid automatic repeat request-acknowledgement (HARQ-ACK) bits for the one or more multicast PDSCHs is one, transmitting, to the BS, a first physical uplink control channel (PUCCH) resource including a NACK (negative acknowledgement) value, and in case that the number of HARQ-ACK bits for the one or more multicast PDSCHs is more than one, transmitting, to the BS, a second PUCCH resource among configured PUCCH resources according to the number of the HARQ-ACK bits.
