1. A method performed by a User Equipment (UE) for Multicast/Broadcast Service (MBS) acquisition, the method comprising:
receiving system information from a Base Station (BS);
determining a first Control Resource Set (CORESET) configuration and a second CORESET configuration based on the system information, the first CORESET configuration for determining a first set of CORESETs scheduling at least one Multicast Control Channel (MCCH), the second CORESET configuration for determining a second set of CORESETs scheduling a plurality of Multicast Traffic Channels (MTCHs);
receiving an MCCH message on the at least one MCCH provided through a first beam of a plurality of beams associated with the BS; and
determining based on the second CORESET configuration and the MCCH message, a plurality of MBS-specific CORESET groups in the second set of CORESETs,
wherein;
each of the plurality of MBS-specific CORESET groups corresponds to a respective MBS session and comprises at least two CORESETs configured to be provided through at least two different beams of the plurality of beams,
a first MBS-specific CORESET group of the plurality of MBS-specific CORESET groups schedules a first set of the plurality of MTCHs for receiving data associated with a first MBS session, and
a second MBS-specific CORESET group of the plurality of MBS-specific CORESET groups schedules a second set of the plurality of MTCHs for receiving data associated with a second MBS session.
