Claim 0:
1. A method for transmitting a signal by a terminal in a wireless communication system, the method comprising:
receiving information about a plurality of periodic uplink (UL) resources for transmission of hybrid automatic repeat request-acknowledgement (HARQ-ACK) information for multicast data;
monitoring a physical downlink control channel (PDCCH) in a search space for multicast configured on a specific downlink frequency resource;
detecting, as a result of the monitoring of the PDCCH, downlink control information (DCI) having a cyclic redundancy check (CRC) scrambled with a group-radio network temporary identifier (G-RNTI),
wherein the DCI includes activation information associated with a first periodic UL resource among the plurality of periodic UL resources; and
based on the first periodic UL resource being activated through the activation information, transmitting, through the first periodic UL resource, a message including the HARQ-ACK information and activation confirmation information set to an index of the activated first periodic UL resource.
