V2X QoS and congestion control for new radio (NR) systems
Embodiments herein provide methods of sidelink communication between nodes including resource selection, congestion control, and/or resource signaling. Other embodiments may be described and claimed.
1. A user equipment (UE) comprising:
one or more processors; and
one or more non-transitory computer-readable storage media comprising instructions that, upon execution of the instructions by the one or more processors, are to cause the UE to:
identify a priority that is related to a physical sidelink channel transmission on a sidelink channel;
transmit a sidelink control information (SCI) that includes an indication of a resource for the physical sidelink channel transmission and an indication of the priority;
increase a power level for transmission of the physical sidelink channel transmission, wherein the increase in the power level is based on the priority; and
transmit the physical sidelink channel transmission on the resource based on the power level.
2. The UE of claim 1 , wherein the instructions are further to perform congestion control on the sidelink channel.
3. The UE of claim 1 , wherein the SCI includes a priority field to indicate the priority.
4. The UE of claim 1 , wherein the priority is related to resource preemption of the physical sidelink channel transmission.
5. The UE of claim 1 , wherein increasing the power level includes increasing the power level based on a plurality of pre-defined power level increase values that are to be applied to a transmission power level of the physical sidelink channel transmission.
6. The UE of claim 5 , wherein the plurality of pre-defined power level increase values includes 3 decibels (dB) and 6 dB.
7. The UE of claim 1 , wherein increasing the power level includes increasing the power level by an amount that is proportional to the priority.
8. One or more non-transitory computer-readable storage media comprising instructions that, upon execution of the instructions by one or more processors of a user equipment (UE), are to cause the UE to:
identify a priority that is related to a physical sidelink channel transmission on a sidelink channel;
transmit a sidelink control information (SCI) that includes an indication of a resource for the physical sidelink channel transmission and an indication of the priority;
increase a power level for transmission of the physical sidelink channel transmission, wherein the increase in the power level is based on the priority; and
transmit the physical sidelink channel transmission on the resource based on the power level.
9. The one or more non-transitory computer-readable media of claim 8 , wherein the instructions are further to perform congestion control on the sidelink channel.
10. The one or more non-transitory computer-readable media of claim 8 , wherein the SCI includes a priority field to indicate the priority.
11. The one or more non-transitory computer-readable media of claim 8 , wherein the priority is related to resource preemption of the physical sidelink channel transmission.
12. The one or more non-transitory computer-readable media of claim 8 , wherein increasing the power level includes increasing the power level based on a plurality of pre-defined power level increase values that are to be applied to a transmission power level of the physical sidelink channel transmission.
13. The one or more non-transitory computer-readable media of claim 8 , wherein increasing the power level includes increasing the power level by an amount that is proportional to the priority.
14. An apparatus for use in a user equipment (UE), wherein the apparatus comprises:
memory to store an indication of a priority that is related to a physical sidelink channel transmission on a sidelink channel; and
one or more processors configured to:
identify the priority;
facilitate transmission of a sidelink control information (SCI) that includes an indication of a resource for the physical sidelink channel transmission and an indication of the priority;
facilitate an increase of a power level for transmission of the physical sidelink channel transmission, wherein the increase in the power level is based on the priority; and
facilitate transmission of the physical sidelink channel transmission on the resource based on the increased power level.
15. The UE of claim 14 , wherein the one or more processors are further configured to perform congestion control on the sidelink channel.
16. The UE of claim 14 , wherein the SCI includes a priority field to indicate the priority.
17. The UE of claim 14 , wherein the priority is related to resource preemption of the physical sidelink channel transmission.
18. The UE of claim 14 , wherein the increase in the power level is based on a plurality of pre-defined power level increase values.
19. The UE of claim 18 , wherein the plurality of pre-defined power level increase values includes 3 decibels (dB) and 6 dB.
20. The UE of claim 14 , wherein the increase in the power level is an amount that is proportional to the priority.
