Classification: CPC H | IPC H

Claim 9:
10. A device configured to control a user equipment (UE) configured to receive a signal in a wireless communication system, the device comprising:
a memory configured to store instructions; and
a processor configured to perform operations by executing the instructions,
wherein the operations performed by the processor comprise:
receiving information regarding one or more group radio network temporary identifiers (G-RNTIs) through higher layer signaling;
receiving a physical downlink control channel (PDCCH) based on the first SSB and the one or more G-RNTIs; and
receiving a physical downlink shared channel (PDSCH) based on the PDCCH,
wherein the received PDCCH is a PDCCH for a multicast broadcast service (MBS) associated with a first G-RNTI from among the one or more G-RNTIs,
wherein the PDSCH carries one or more codewords for the MBS,
wherein a scrambling sequence for each codeword of the PDSCH is initialized based on a formula ‘nRNTI*215+q*214+nID’, where ‘q’ is a codeword index,
wherein based on that the PDCCH is the PDCCH for the MBS which is received based on the first G-RNTI, the processor determines ‘nRNTI’ to be the first G-RNTI, and ‘nID’ to be a first scrambling ID,
wherein in a case where a higher-layer parameter ‘dataScramblingIdentityPDSCH’ is configured for the MBS, the first scrambling ID is determined to be the higher-layer parameter ‘dataScramblingIdentityPDSCH’, and
wherein in a case where the higher-layer parameter ‘dataScramblingIdentityPDSCH’ is not configured for the MBS, the first scrambling ID is determined to be a cell ID.
