Methods and devices to determine the quality of service mechanisms for vehicle-to-everything mobile device communications
A method performed by a WTRU may comprise determining application layer information and receiving QoS policy configuration information. A QoS mechanism may be determined based on the application layer information and the received QoS policy configuration information. A QoS value applicable to the determined QoS mechanism may then be determined for a data packet. Subsequently, the determined QoS value may be transmitted to another WTRU over a PC5 interface, with or without the data packet. The QoS mechanism may be determined as one of a PPPP mechanism or a QFI mechanism. The QoS policy configuration information may be received via a gNB. In an embodiment, the application layer information may include an application identifier, a PSID or an ITS-AID. The QoS policy configuration information may indicate a mapping of V2X application IDs to respective QoS mechanisms.
1. A wireless transmit/receive unit (WTRU) comprising a processor and memory, the processor and memory configured to:
determine application layer information associated with a vehicle-to-everything (V2X) service;
receive quality of service (QOS) policy configuration information from a network, wherein the QoS policy configuration information comprises a mapping of a V2X identifier associated with the V2X service to at least one flow based QoS parameter;
apply a per-flow based QoS mechanism for device-to-device communications for the V2X service in accordance with the at least one flow based QoS parameter associated with the V2X identifier associated with the V2X service; and
transmit information indicative of the at least one flow based QoS parameter to a radio access network.
2. The WTRU of claim 1 , wherein the at least one flow based Qos parameter comprises at least one of a packet delay budget (PDB), a packet error rate (PER), or a priority.
3. The WTRU of claim 1 , wherein the V2X identifier is associated with a geographic area.
4. The WTRU of claim 1 , wherein the per-flow based QoS mechanism for device-to-device communications for the V2X service is applied, based at least in part, on a geographic location of the WTRU.
5. The WTRU of claim 1 , wherein the QoS policy configuration information is received via a next generation Node B (gNB).
6. The WTRU of claim 1 , the processor and memory further configured to transmit the information indicative of the at least one flow based QoS parameter over a PC5 interface.
7. A method performed by a wireless transmit/receive unit (WTRU), the method comprising:
determining application layer information associated with a vehicle-to-everything (V2X) service;

applying a per-flow based QoS mechanism for device-to-device communications for the V2X service in accordance with the at least one flow based QoS parameter associated with the V2X identifier associated with the V2X service;

8. The method of claim 7 , wherein the at least one flow based QoS parameter comprises at least one of a packet delay budget (PDB), a packet error rate (PER), or a priority.
9. The method of claim 7 , wherein the V2X identifier is associated with a geographic area.
10. The method of claim 7 , wherein applying the per-flow based QoS mechanism for device-to-device communications for the V2X service is based at least in part, on a geographic location of the WTRU.
11. The method of claim 7 , wherein the QoS policy configuration information is received via a next generation Node B (gNB).
12. The method of claim 7 , further comprising transmitting the information indicative of the at least one flow based QoS parameter over a PC5 interface.
