Procedure enabling configuration of PC5 communication parameters for advanced vehicle to everything (V2X) services
Methods and apparatuses are described herein for dynamic PC5 communication adaptation. For example, a UE may receive, from a vehicle-to-everything control function (V2X CF) or a vehicle-to-everything application server (V2X AS), a V2X provisioning message that includes a first transmission profile and determine, based on the first transmission profile, a first range to configure PC5 communication of a plurality of UEs associated with the V2X platoon. When a number of UEs joining the V2X platoon exceeds a certain threshold, the UE may transmit, to the V2X CF or the V2X AS, a modification request message requesting a second transmission profile. The UE may receive, from the V2X CF or the V2X AS, a modification response message that includes the second transmission profile and determine, based on the second transmission profile, a second range to reconfigure the PC5 communication of the plurality of UEs associated with the V2X platoon.
1. A method for use in a wireless transmit/receive unit (WTRU), the method comprising:
receiving, from a vehicle to everything application server (V2X AS), a V2X provisioning message that includes a plurality of V2X group-related parameters indicating a role of the WTRU in a V2X group, a size of the V2X group and a V2X group identifier associated with the V2X group, wherein the V2X group comprises a plurality of WTRUs for group-based PC5 communication; and
transmitting the plurality of V2X group-related parameters to the plurality of WTRUs to enable the group-based PC5 communication, wherein a transmission range associated with the V2X group-related parameters is determined based on mapping information received from a V2X control function (V2X CF).
2. The method of claim 1 , wherein the transmission range is determined based on pre-stored mapping information in the WTRU.
3. The method of claim 1 , wherein the transmission range is a distance that a signal can reach within the V2X group or a distance between the plurality of WTRUs within the V2X group.
4. The method of claim 1 , wherein the mapping information received from the V2X CF includes a range mapping table specifying range values corresponding to a required coverage.
5. The method of claim 1 , wherein the mapping information is received on a condition that the WTRU is a leader in the V2X group.
6. The method of claim 1 , wherein the mapping information is provisioned in policy and parameters configuration information from the V2X CF.
7. The method of claim 1 , wherein the role of the WTRU in the V2X group is a leader or a follower.
8. The method of claim 1 , wherein the size of the V2X group is a maximum number of allowed WTRUs in the V2X group.
9. The method of claim 1 , wherein a plurality of V2X group-related parameters further include a maximum size of a WTRU, an arrangement of the V2X group and a type of required communication between WTRUs in the V2X group.
10. The method of claim 1 , wherein the V2X group identifier is converted to a layer 2 identifier set to the V2X group for the group-based PC5 communication.
11. A wireless transmit/receive unit (WTRU) comprising:
a processor;
a receiver; and
a transmitter, the processor and the receiver configured to receive, from a vehicle to everything application server (V2X AS), a V2X provisioning message that includes a plurality of V2X group-related parameters indicating a role of the WTRU in a V2X group, a size of the V2X group and a V2X group identifier associated with the V2X group, wherein the V2X group comprises a plurality of WTRUs for group-based PC5 communication; and
the processor and the transmitter configured to transmit the plurality of V2X group-related parameters to the plurality of WTRUs to enable the group-based PC5 communication, wherein a transmission range associated with the V2X group-related parameters is determined based on mapping information received from a V2X control function (V2X CF).
12. The WTRU of claim 11 , wherein the transmission range is determined based on pre-stored mapping information in the WTRU.
13. The WTRU of claim 11 , wherein the transmission range is a distance that a signal can reach within the V2X group or a distance between the plurality of WTRUs within the V2X group.
14. The WTRU of claim 11 , wherein the mapping information received from the V2X CF includes a range mapping table specifying range values corresponding to a required coverage.
15. The WTRU of claim 11 , wherein the mapping information is received on a condition that the WTRU is a leader in the V2X group.
16. The WTRU of claim 11 , wherein the mapping information is provisioned in policy and parameters configuration information from the V2X CF.
17. The WTRU of claim 11 , wherein the role of the WTRU in the V2X group is a leader or a follower.
18. The WTRU of claim 11 , wherein the size of the V2X group is a maximum number of allowed WTRUs in the V2X group.
19. The WTRU of claim 11 , wherein a plurality of V2X group-related parameters further include a maximum size of a WTRU, an arrangement of the V2X group and a type of required communication between WTRUs in the V2X group.
