Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a misbehavior condition in a local vehicle-to-everything (V2X) information source. The UE may receive an incoming V2X message. The UE may generate a misbehavior decision for the incoming V2X message based at least in part on the misbehavior condition in the local V2X information source. Numerous other aspects are described.

First claim

What is claimed is:

1 . A method of wireless communication performed by a user equipment (UE), comprising:
detecting, via an on-board unit of the UE, a misbehavior condition in a local vehicle-to-everything (V2X) information source, wherein the local V2X information source comprises a local global navigation satellite system (GNSS) receiver; receiving an incoming V2X message; and generating, via a receive-side local misbehavior detection system of the on-board unit, a misbehavior decision for the incoming V2X message based at least in part on the misbehavior condition in the local V2X information source and information corresponding to one or more previously received V2X messages;
wherein generating the misbehavior decision for the incoming V2X message includes assigning a lower weight to one or more inputs from the local V2X information source associated with the misbehavior condition, and disabling the receive-side local misbehavior detection system based at least in part on a number of local V2X information sources associated with misbehavior conditions equaling or exceeding a threshold, and
wherein, in response to detecting the misbehavior condition in the local GNSS receiver, the on-board unit initiates a system-level action to stop operation of a position overlap detector that relies on inputs from the local GNSS receiver.

2 . The method of claim 1 , wherein generating the misbehavior decision for the incoming V2X message includes filtering or ignoring one or more inputs from the local V2X information source associated with the misbehavior condition.

3 . The method of claim 1 , wherein generating the misbehavior decision for the incoming V2X message includes enabling or disabling one or more misbehavior detectors that are configured to receive one or more inputs from the local V2X information source associated with the misbehavior condition.

4 . The method of claim 1 , wherein generating the misbehavior decision for the incoming V2X message includes modifying one or more misbehavior detection parameters based at least in part on an error or an uncertainty caused by the misbehavior condition associated with the local V2X information source.

5 . The method of claim 1 , further comprising:
transmitting, to a management entity, a report that includes information associated with the misbehavior condition.

6 . The method of claim 1 , wherein generating the misbehavior decision for the incoming V2X message includes obtaining one or more inputs from a backup data source for the local V2X information source.

7 . The method of claim 1 , wherein the misbehavior condition is detected in the local V2X information source by a transmit-side local misbehavior detection system of the on-board unit.

8 . A user equipment (UE) for wireless communication, comprising:
one or more memories; and one or more processors, coupled to the one or more memories, configured to:
detect, via an on-board unit of the UE, a misbehavior condition in a local vehicle-to-everything (V2X) information source, wherein the local V2X information source comprises a local global navigation satellite system (GNSS) receiver;
receive an incoming V2X message; and
generate, via a receive-side local misbehavior detection system of the on-board unit, a misbehavior decision for the incoming V2X message based at least in part on the misbehavior condition in the local V2X information source and one or more previously received V2X messages;
wherein the one or more processors, to generate the misbehavior decision for the incoming V2X message, are configured to:
assign a lower weight to one or more inputs from the local V2X information source associated with the misbehavior condition,
disable the receive-side local misbehavior detection system based at least in part on a number of local V2X information sources associated with misbehavior conditions equaling or exceeding a threshold, and
in response to detecting the misbehavior condition in the local GNSS receiver, initiate a system-level action to stop operation of a position overlap detector that relies on inputs from the local GNSS receiver.

9 . The UE of claim 8 , wherein the one or more processors, to generate the misbehavior decision for the incoming V2X message, are configured to filter or ignore one or more inputs from the local V2X information source associated with the misbehavior condition.

10 . The UE of claim 8 , wherein the one or more processors, to generate the misbehavior decision for the incoming V2X message, are configured to enable or disable one or more misbehavior detectors that are configured to receive one or more inputs from the local V2X information source associated with the misbehavior condition.

11 . The UE of claim 8 , wherein the one or more processors, to generate the misbehavior decision for the incoming V2X message, are configured to modify one or more misbehavior detection parameters based at least in part on an error or an uncertainty caused by the misbehavior condition associated with the local V2X information source.

12 . The UE of claim 8 , wherein the one or more processors are further configured to:
transmit, to a management entity, a report that includes information associated with the misbehavior condition.

13 . The UE of claim 8 , wherein the one or more processors, to generate the misbehavior decision for the incoming V2X message, are configured to obtain one or more inputs from a backup data source for the local V2X information source.

14 . The UE of claim 8 , wherein the misbehavior condition is detected in the local V2X information source by a transmit-side local misbehavior detection system of the on-board unit.

15 . A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:
one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to:
detect, via an on-board unit of the UE, a misbehavior condition in a local vehicle-to-everything (V2X) information source, wherein the local V2X information source comprises a local global navigation satellite system (GNSS) receiver;
receive an incoming V2X message; and
generate, via a receive-side local misbehavior detection system of the on-board unit, a misbehavior decision for the incoming V2X message based at least in part on the misbehavior condition in the local V2X information source and one or more previously received V2X messages;
wherein the one or more instructions, that cause the UE to generate the misbehavior decision for the incoming V2X message, cause the UE to:
assign a lower weight to one or more inputs from the local V2X information source associated with the misbehavior condition,
disable the receive-side local misbehavior detection system based at least in part on a number of local V2X information sources associated with misbehavior conditions equaling or exceeding a threshold, and
in response to detecting the misbehavior condition in the local GNSS receiver, initiate a system-level action to stop operation of a position overlap detector that relies on inputs from the local GNSS receiver.

16 . The non-transitory computer-readable medium of claim 15 , wherein the one or more instructions, that cause the UE to generate the misbehavior decision for the incoming V2X message, cause the UE to filter or ignore one or more inputs from the local V2X information source associated with the misbehavior condition.

17 . The non-transitory computer-readable medium of claim 15 , wherein the one or more instru
