Abstract

Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive sidelink control information (SCI) associated with a remote vehicle; identify a threat metric associated with the remote vehicle based at least in part on one or more characteristics of the remote vehicle, wherein the one or more characteristics are determined based at least in part on vehicle information received in one or more transport blocks corresponding to prior SCI associated with the remote vehicle and received prior to the SCI; and process the SCI based at least in part on the threat metric. Numerous other aspects are provided.

Claims

1. A method of wireless communication performed by a user equipment (UE), comprising:

receiving sidelink control information (SCI) associated with a remote vehicle;

identifying a threat metric associated with the remote vehicle based at least in part on one or more characteristics of the remote vehicle,

wherein the threat metric indicates a degree to which the remote vehicle presents a threat to a vehicle associated with the UE, and

wherein the one or more characteristics are determined based at least in part on vehicle information received in one or more transport blocks corresponding to previously received SCI associated with the remote vehicle and received prior to the SCI;

processing the SCI based at least in part on the threat metric; and

transmitting information associated with the processed SCI to influence an operation of the vehicle associated with the UE.

2. The method of claim 1, wherein the SCI and the previously received SCI both include a same vehicle identifier that identifies the remote vehicle.

3. The method of claim 2, wherein the threat metric is identified based at least in part on a stored indication of an association between the same vehicle identifier and the threat metric.

4. The method of claim 3, wherein the stored indication of the association is stored based at least in part on analyzing the vehicle information received in the one or more transport blocks corresponding to the previously received SCI.

5. The method of claim 1, wherein the one or more characteristics include at least one of:

a type of vehicle-to-everything (V2X) message received from the remote vehicle,

a location of the remote vehicle,

a time at which the remote vehicle was located at the location,

a speed or velocity of the remote vehicle,

an acceleration of the remote vehicle,

a trajectory of the remote vehicle,

a size of the remote vehicle,

a driving pattern associated with the remote vehicle, or

some combination thereof.

6. The method of claim 1, wherein the threat metric is determined based at least in part on sensor data measured in connection with the remote vehicle.

7. The method of claim 1, wherein the SCI is processed at a rate determined based at least in part on the threat metric.

8. The method of claim 1, wherein processing of the SCI is prioritized based at least in part on the threat metric.

9. The method of claim 1, wherein the SCI is scheduled for processing at a particular time determined based at least in part on the threat metric.

10. The method of claim 1, wherein the SCI is processed based at least in part on a list of vehicle identifiers, corresponding to SCI, sorted according to corresponding threat metrics.

11. The method of claim 1, wherein processing the SCI comprises at least one of demodulating or decoding the SCI and at least one transport block corresponding to the SCI.

12. The method of claim 1, wherein processing the SCI comprises preventing at least one of demodulating or decoding of at least one transport block corresponding to the SCI.

13. The method of claim 1, further comprising modifying the threat metric based at least in part on a change in the one or more characteristics.

14. A user equipment (UE) for wireless communication, comprising:

memory; and

one or more processors operatively coupled to the memory, the memory and the one or more processors configured to;

receive sidelink control information (SCI) associated with a remote vehicle;

identify a threat metric associated with the remote vehicle based at least in part on one or more characteristics of the remote vehicle,

wherein the threat metric indicates a degree to which the remote vehicle presents a threat to a vehicle associated with the UE, and

wherein the one or more characteristics are determined based at least in part on vehicle information received in one or more transport blocks corresponding to previously received SCI associated with the remote vehicle and received prior to the SCI;

process the SCI based at least in part on the threat metric; and

transmit information associated with the processed SCI to influence an operation of the vehicle associated with the UE.

15. The UE of claim 14, wherein the SCI and the previously received SCI both include a same vehicle identifier that identifies the remote vehicle.

16. The UE of claim 15, wherein the threat metric is identified based at least in part on a stored indication of an association between the same vehicle identifier and the threat metric.

17. The UE of claim 16, wherein the stored indication of the association is stored based at least in part on analyzing the vehicle information received in the one or more transport blocks corresponding to the previously received SCI.

18. The UE of claim 14, wherein the one or more characteristics include at least one of:
