Techniques are provided for filtering object detection information provided via V2X communication links. An example method for partially filtering a sensor data sharing message includes receiving the sensor data sharing message from a vehicle, decoding a first portion of the sensor data sharing message to determine an area of interest associated with the vehicle, determine a relative position of the area of interest, and decoding or discarding a second portion of the sensor data sharing message based on the relative position of the area of interest.

Filtering V2X sensor data messages

A method of wireless communication at a first V2X device is described herein. The method includes obtaining a message including a MAC header, an L1 source ID, and an L1 destination ID. The method includes decoding the MAC header to produce an L2 source ID associated with the message based on at least one of (1) the L1 destination ID of the message matching a first number of bits of an L2 source ID of the first V2X device or (2) the L1 source ID of the message matching a second number of bits of the L2 source ID of the first V2X device. The method includes outputting an indication of a MAC cloning attack based on the L2 source ID of the message matching the L2 source ID of the first V2X device.

MAC address cloning attack detection for V2X devices

Systems and techniques are described for providing optimized vehicle-to-everything (V2X) safety messages over a wide area network (Uu) interface. For example, method for wireless communications may include receiving, by a network device, one or more first messages from one or more vehicles. Each of the first message(s) includes vehicle information associated with a respective vehicle of the vehicle(s). The method may include determining, at the network device, one or more recipient vehicles for one or more second messages based on at least a portion of the vehicle information from the first message(s) and characteristics associated with a respective recipient vehicle of the recipient vehicle(s). The method may include transmitting, at the network device, the second message(s) to the recipient vehicle(s).

Optimized vehicle-to-everything (V2X) messaging

Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, an example of a process includes determining, at the first network device, an estimated location of a second network device. The process may further include comparing, at the first network device, the estimated location with an expected location for the second network device. The process may include determining, at the first network device, whether the second network device is a misbehaving device based on the comparing. The process may further include generating, at the first network device, a report based on the determining of whether the second device is a misbehaving device.

Misbehavior detection service for sharing connected and sensed objects

Systems and techniques are described for assigning a reputation score for vehicle-to-everything (V2X) communications. For example, a process may include receiving, at a receiving device (e.g., a vehicle, network entity, etc.), vehicle-based messages from a transmitting device (e.g., a vehicle, network-equipped infrastructure, etc.). Each of the vehicle-based messages includes information associated with the transmitting device. The process may include determining, at the receiving device, a reputation score for the transmitting device based on at least a portion of the information associated with the transmitting device from each vehicle-based message of the plurality of vehicle-based messages.

Reputation score assignment for vehicle-based communications

Systems and techniques are described for sidelink synchronization source selection. For example, a method for wireless communications at a user equipment (UE) may include transmitting, from the UE to a target UE, a message including information associated with a first synchronization reference source associated with the UE. The method may include receiving, at the UE from the target UE in response to the message, a response message including an indication of whether the target UE can use the first synchronization reference source for sidelink positioning. The method can further include determining, at the UE based on the response message, whether to use the first synchronization reference source or a different synchronization reference source as a master synchronization reference source for the sidelink positioning.

Sidelink synchronization source selection

Disclosed are techniques for performing wireless communication. In some aspects, a wireless communication device may determine that a prospective position of the wireless communication device is in a geographic area associated with a deficient global navigation satellite system (GNSS) signal. In some cases, the wireless communications device can transmit a sidelink synchronization signal to at least one user equipment (UE) device that is located within the geographic area associated with the deficient GNSS signal.

Optimizing transmission of a sidelink synchronization signal by a wireless device

Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, an example of a process includes detecting an object based on sensor data from at least one sensor of the network device. The process further includes receiving, by the network device, a vehicle-based message comprising message data related to the object. The process further includes comparing, by the network device, the sensor data and the message data and detecting, by the network device, malicious behavior based on the comparing.

Systems and techniques are described for validating object detection. For example, an apparatus can receive a message from a wireless device. The message includes object data corresponding to one or more objects reported by the wireless device to be within a field-of-view of the apparatus. The apparatus can further determine, based on the object data, whether the wireless device has misreported at least one of the one or more objects.

Misbehavior detection using sensor sharing and collective perception

Method and apparatus for cooperative early threat detection. In some aspects, the apparatus detects one or more object data signals having data that interferes with wireless resources utilized in automated driving decisions. The apparatus transmits, to at least a second wireless device, a message indicating the one or more object data signals having the data that interferes with wireless resources utilized in automated driving decisions. The one or more object data signals may correspond to a misbehaving wireless device. The data of the misbehaving wireless device may comprise implausible data related to at least one characteristic of the misbehaving wireless device.

For example, a system can receive, from a navigation system, navigation timestamp information at a first instance and a second instance. The system can determine a navigation system time difference based on the navigation timestamp information at the first instance and the second instance. The system can further receive, from a wireless device, network timestamp information at the first instance and the second instance. The system can determine a network time difference based on the network timestamp information at the first instance and the second instance. The system can further determine whether time reporting by the navigation system is correct based on the navigation system time difference and the network time difference.
