Method for transmitting and receiving signal by terminal in wireless communication system
An embodiment relates to a method for a first terminal operating in a wireless communication system, the method comprising the steps of: transmitting application information from an application layer to a vehicle-to-everything (V2X) layer; generating, in the V2X layer, sidelink (SL) discontinuous reception (DRX) information on the basis of the application information; transmitting the SL DRX information from the V2X layer to an AS layer; and communicating with a second terminal by applying the SL DRX information in the AS layer, wherein the application information includes at least one application requirement.
1. A method for a first user equipment (UE) operating in a wireless communication system, the method comprising:
determining a service type identified based on an intelligent transport systems-application object identifier (ITS-AID) or a provider service identifier (PSID);
configuring sidelink (SL) discontinuous reception (DRX) for groupcast based on the service type and a layer-2 identifier; and
monitoring first sidelink control information (SCI) based on the SL DRX,
wherein the SL DRX is configured with parameters including SL drx-onDurationTimer, SL drx-InactivityTimer, SL drx-RetransmissionTimer and SL drx-HARQ-RTT-Timer.
2. The method according to claim 1 , wherein the parameters further includes at least one of SL drx-SlotOffset, SL drx-LongCycleStartOffset, SL drx-ShortCycle, SL drx-ShortCycleTimer.
3. The method according to claim 1 , wherein the SL DRX is transmitted to other UEs which are not connected to the first UE.
4. The method according to claim 1 , wherein the SL DRX is transmitted to a second UE through a physical sidelink broadcast channel (PSBCH).
5. The method according to claim 1 , wherein the SL DRX is transmitted to a second UE through second sidelink control information (SCI).
6. The method according to claim 5 , wherein first SCI includes an indicator indicating whether the SL DRX is included in the second SCI.
7. The method according to claim 5 , wherein based on a part of the SL DRX being included in the second SCI, remaining SL DRX is transmitted to the second UE through a physical sidelink shared channel (PSSCH).
8. The method according to claim 7 , wherein the second SCI includes an indicator indicating whether the remaining SL DRX is included in the PSSCH.
9. The method according to claim 1 , wherein the SL DRX is transmitted to a second UE through a PSSCH.
10. A first user equipment (UE) configured to operate in a wireless communication system, the first UE comprising:
at least one processor; and
at least one computer memory operably coupled to the at least one processor and storing instructions which when executed, cause the at least one processor to perform operations,
wherein the operations include:
determining a service type identified based on an intelligent transport systems-application object identifier (ITS-AID) or a provider service identifier (PSID);
configuring sidelink (SL) discontinuous reception (DRX) for groupcast based on the service type and a layer-2 identifier; and
monitoring first sidelink control information (SCI) based on the SL DRX,
wherein the SL DRX is configured with parameters including SL drx-onDurationTimer, SL drx-InactivityTimer, SL drx-RetransmissionTimer and SL drx-HARQ-RTT-Timer.
11. A processor for performing operations for a first user equipment (UE) configured to operate in a wireless communication system,
wherein the operations include:
determining service type identified based on an intelligent transport systems-application object identifier (ITS-AID) or a provider service identifier (PSID);
configuring sidelink (SL) discontinuous reception (DRX) for groupcast based on the service type and a layer-2 identifier; and
monitoring first sidelink control information (SCI) based on the SL DRX,
wherein the SL DRX is configured with parameters including SL drx-onDurationTimer, SL drx-InactivityTimer, SL drx-RetransmissionTimer and SL drx-HARQ-RTT-Timer.
12. The first UE according to claim 10 , wherein the first UE communicates with at least one of another UE, a UE related to an autonomous driving vehicle, a base station, or a network.
