Assignee: LG ELECTRONICS INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 9:
10. A device configured to control a terminal in a wireless communication system, the device comprising:
a memory configured to store instructions; and
a processor configured to execute the instructions to perform operations,
wherein the operations comprise:
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; and
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
wherein, based on the first periodic UL resource being activated through the activation information, the operations further comprise 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.
