Patent ID: 11784761

Abstract:
A method performed by a terminal in a wireless communication system according to an embodiment of the present disclosure comprises the steps of: receiving a group-common transmission regarding a TB from a network; transmitting hybrid automatic repeat request (HARQ) acknowledgement (ACK) or non-acknowledgement (NACK) information regarding the group-common transmission to the network, on the basis of whether the TB is successfully decoded; and receiving first transmission from the network after a first round trip time (RTT) has lapsed since transmission of the HARQ ACK/NACK information regarding the group-common transmission. The first transmission corresponds to group-common transmission or terminal-specific transmission. The first transmission may correspond to retransmission of the TB on the basis that the first transmission is terminal-specific transmission associated with the same HARQ process as the group-common transmission, and that a new data indicator (NDI) value is not toggled.
