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 performed by a user equipment (UE) configured to operate in a wireless communication system, the method comprising:
determining a vehicle-to-everything (V2X) service type,
wherein the V2X service type is identified based on at least one of: an intelligent transport systems application identifier (ITS-AID) or a provider service identifier (PSID);
obtaining configuration information related to sidelink (SL) discontinuous reception (DRX) to configure DRX related parameters for SL groupcast and broadcast communication;
performing sidelink control information (SCI) monitoring based on the SL DRX; and
performing, based on the SCI, groupcast communication related to the SL DRX,
wherein the SL DRX is configured based on quality of service (QOS) related to the V2X service type and a layer-2 identifier (L2 ID), and
wherein the DRX related parameters comprise: SL on-duration timer, SL inactivity-timer, SL hybrid automatic repeat and request (HARQ) round trip time (RTT) timer and SL retransmission timer.
2. The method of claim 1 , wherein the DRX related parameters further comprise at least one of: SL drx-SlotOffset, SL drx-LongCycleStartOffset, SL drx-ShortCycle, or SL drx-ShortCycleTimer.
3. The method of claim 1 , wherein the SL DRX is commonly configured for multiple UEs comprising the UE.
4. The method of claim 3 , wherein the multiple UEs comprise at least one UE, and
wherein a radio resource control (RRC) connection is not established between the UE and the at least one UE.
5. The method of claim 3 , wherein the SL DRX is commonly configured for the multiple UEs based on at least one of: a physical sidelink broadcast channel (PSBCH), a physical sidelink control channel (PSCCH) or a physical sidelink shared channel (PSSCH).
6. A user equipment (UE) configured to operate in a wireless communication system, the UE comprising:
a transceiver; and
at least one processor coupled with the transceiver,
wherein the at least one processor is configured to:
determine a vehicle-to-everything (V2X) service type,
wherein the V2X service type is identified based on at least one of: an intelligent transport systems application identifier (ITS-AID) or a provider service identifier (PSID);
obtain configuration information related to sidelink (SL) discontinuous reception (DRX) to configure DRX related parameters for SL groupcast and broadcast communication;
perform sidelink control information (SCI) monitoring based on the SL DRX; and
perform, based on the SCI, groupcast communication related to the SL DRX,
wherein the SL DRX is configured based on quality of service (QOS) related to the V2X service type and a layer-2 identifier (L2 ID), and
wherein the DRX related parameters comprise: SL on-duration timer, SL inactivity-timer, SL hybrid automatic repeat and request (HARQ) round trip time (RTT) timer and SL retransmission timer.
