According to the various embodiments, a method of transmitting and receiving signals in a wireless communication system and apparatus for supporting the same may be provided. ## Claims ### Claim 1 A method of performing a semi-persistent scheduling (SPS) operation by a user equipment (UE) in a wireless communication system, the method comprising: receiving information on multiple SPS configurations including a UE-specific SPS configuration and a multicast SPS configuration configured with different SPS configuration indexes; activating the multicast SPS configuration based on a reception of downlink control information (DCI) with a cyclic redundancy check (CRC) scrambled by a group-Configured Scheduling (G-CS)-radio network temporary identifier (RNTI); and receiving a SPS PDSCH (physical downlink shared channel) including a MAC PDU (Medium Access Control Protocol Data Unit) based on the multicast SPS configuration, wherein the UE determines whether to obtain a data unit included in the MAC PDU based on an identifier related to a service included in the sub-header of the MAC PDU. ### Claim 2 (depends on 1) The method according to claim 1, wherein the DCI includes scheduling information for SPS physical downlink shared channel (PDSCH) for the multicast. ### Claim 3 (depends on 1) The method according to claim 1, wherein the UE-specific SPS configuration is activated only by a DCI with the CRC scrambled by the CS-RNTI. ### Claim 4 (depends on 1) The method according to claim 1, wherein, based on a plurality of services being mapped to the G-CS-RNTI, whether each of the plurality of services is needed is determined based on the identifier related to the service included in the sub-header of the MAC PDU. ### Claim 5 A user equipment (UE) configured to operate in a wireless communication system, the UE comprising: at least one transceiver; and at least one processor connected to the at least one transceiver, wherein the at least one processor is configured to control the at least one transceiver to: receive information on multiple SPS configurations including a UE-specific SPS configuration and a multicast SPS configuration configured with different SPS configuration indexes; activate the multicast SPS configuration based on a reception of downlink control information (DCI) with a cyclic redundancy check (CRC) scrambled by a group-Configured Scheduling (G-CS)-radio network temporary identifier (RNTI); receive a SPS PDSCH (physical downlink shared channel) including a MAC PDU (Medium Access Control Protocol Data Unit) based on the multicast SPS configuration; and determine whether to obtain a data unit included in the MAC PDU based on an identifier related to a service included in the sub-header of the MAC PDU. ### Claim 6 A method of performing a semi-persistent scheduling (SPS) operation by a base station in a wireless communication system, the method comprising: transmitting information on multiple SPS configurations including a UE-specific SPS configuration and a multicast SPS configuration configured with different SPS configuration indexes; transmitting downlink control information (DCI) with a cyclic redundancy check (CRC) scrambled by a group-Configured Scheduling (G-CS)-radio network temporary identifier (RNTI) to activate the multicast SPS configuration; and transmitting a SPS PDSCH (physical downlink shared channel) including a MAC PDU (Medium Access Control Protocol Data Unit) based on the multicast SPS configuration; and wherein whether or not to obtain a data unit included in the MAC PDU is determined based on an identifier related to a service included in the sub-header of the MAC PDU. ### Claim 7 (depends on 6) The method according to claim 6, wherein the DCI includes scheduling information for SPS physical downlink shared channel (PDSCH) for the multicast. ### Claim 8 (depends on 6) The method according to claim 6, wherein the UE-specific SPS configuration is activated only by the DCI with the CRC scrambled by the CS-RNTI. ### Claim 9 (depends on 6) The method according to claim 6, wherein, based on a plurality of services being mapped to the G-CS-RNTI, whether each of the plurality of services is needed is determined based on the identifier related to the service included in the sub-header of the MAC PDU. ### Claim 10 A base station configured to operate in a wireless communication system, the base station comprising: at least one transceiver; and at least one processor connected to the at least one transceiver, wherein the at least one processor is configured to control the at least one transceiver to: transmit information on multiple SPS configurations including a UE-specific SPS configuration and a multicast SPS configuration configured with different SPS configuration indexes; transmit downlink control information (DCI) with a cyclic redundancy check (CRC) scrambled by a group-Configured Scheduling (G-CS)-radio network temporary identifier (RNTI) to activate the multicast SPS configuration; and transmit a SPS PDSCH (physical downlink shared channel) including a MAC PDU (Medium Access Control Protocol Data Unit) based on the multicast SPS configuration; and, wherein whether or not to obtain a data unit included in the MAC PDU is determined based on an identifier related to a service included in the sub-header of the MAC PDU. ### Claim 11 At least one computer-readable memory operably connected to at least one processor and storing instructions that, based on being executed by the at least one processor, control a user equipment operating in a wireless communication system to perform operations comprising: receiving information on multiple SPS configurations related to each of SPS configuration indexes including a UE-specific SPS configuration and a multicast SPS configuration configured with different SPS configuration indexes; activating the multicast SPS configuration based on a reception of first-downlink control information (DCI) with a cyclic redundancy check (CRC) scrambled by a group-Configured Scheduling (G-CS)-radio network temporary identifier (RNTI); and receiving a SPS PDSCH (physical downlink shared channel) including a MAC PDU (Medium Access Control Protocol Data Unit) based on the multicast SPS configuration; and wherein whether or not to obtain a data unit included in the MAC PDU is determined based on an identifier related to a service included in the sub-header of the MAC PDU.
