A method of receiving a signal by a user equipment, UE, in a wireless communication system, the method comprising: receiving at least one physical downlink control channel, PDCCH, carrying downlink control information based on configuration information for at least one control resource set, CORESET; and receiving at least one physical downlink shared channel, PDSCH, based on the at least one PDCCH, characterized in that wherein, based on that i) the at least one PDCCH includes a first PDCCH carrying unicast DCI and ii) the at least PDSCH includes a unicast PDSCH scheduled by the unicast DCI, iii) the unicast DCI does not include a transmission configuration indication, TCI, field, and iv) a time offset between the first PDCCH and the unicast PDSCH is equal to or greater than a first threshold, the UE determines that a TCI state or a quasi-co-location, QCL, assumption for the unicast PDSCH is identical to a TCI state or a QCL assumption for a first CORESET related to the first PDCCH, wherein, based on that v) the at least one PDCCH includes a second PDCCH carrying multicast DCI and vi) the at least PDSCH includes a multicast PDSCH scheduled by the multicast DCI, vii) the multicast DCI does not include a TCI field, and viii) a time offset between the second PDCCH and the multicast PDSCH is equal to or greater than a second threshold, the UE determines that a TCI state or a QCL assumption for the multicast PDSCH is identical to a TCI state or a QCL assumption for a second CORESET related to the second PDCCH, wherein, for the TCI state or the QCL assumption for the unicast PDSCH, the UE determines the first threshold to be a first value related to the UE's own capability reported by the UE, and wherein, for the TCI state or the QCL assumption for the multicast PDSCH, the UE determines the second threshold to be a second value related to a lowest UE capability for supporting the multicast PDSCH. receiving at least one physical downlink control channel, PDCCH, carrying downlink control information based on configuration information for at least one control resource set, CORESET; and receiving at least one physical downlink shared channel, PDSCH, based on the at least one PDCCH, characterized in that wherein, based on that i) the at least one PDCCH includes a first PDCCH carrying unicast DCI and ii) the at least PDSCH includes a unicast PDSCH scheduled by the unicast DCI, iii) the unicast DCI does not include a transmission configuration indication, TCI, field, and iv) a time offset between the first PDCCH and the unicast PDSCH is equal to or greater than a first threshold, the UE determines that a TCI state or a quasi-co-location, QCL, assumption for the unicast PDSCH is identical to a TCI state or a QCL assumption for a first CORESET related to the first PDCCH, wherein, based on that v) the at least one PDCCH includes a second PDCCH carrying multicast DCI and vi) the at least PDSCH includes a multicast PDSCH scheduled by the multicast DCI, vii) the multicast DCI does not include a TCI field, and viii) a time offset between the second PDCCH and the multicast PDSCH is equal to or greater than a second threshold, the UE determines that a TCI state or a QCL assumption for the multicast PDSCH is identical to a TCI state or a QCL assumption for a second CORESET related to the second PDCCH, wherein, for the TCI state or the QCL assumption for the unicast PDSCH, the UE determines the first threshold to be a first value related to the UE's own capability reported by the UE, and wherein, for the TCI state or the QCL assumption for the multicast PDSCH, the UE determines the second threshold to be a second value related to a lowest UE capability for supporting the multicast PDSCH.
