Abstract
Various embodiments of the present disclosure relate to a next-generation wireless communication system for supporting high data transfer rates beyond the 4th generation (4G) wireless communication system. 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.
Claims11
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.
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.
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.
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.
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.
