Abstract: Various embodiments include methods and computing devices implementing such methods for detecting and responding to a non-acknowledgment message (NACK) attack. In some embodiments, a device vehicle processing system may perform an operation to determine whether a NACK attacker is present in response to a quantity of NACK messages received within a time interval exceeding a threshold quantity that is based on a vehicle communication environment proximate to the vehicle. The vehicle processing system may perform an operation to mitigate adverse effects of NACK messages received from the NACK attacker in response to determining that the NACK attacker is present.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a communication. The UE may transmit hybrid automatic repeat request (HARQ) feedback for the communication, wherein the HARQ feedback indicates whether the communication is decoded and whether a message is verified. Numerous other aspects are described.

Abstract: Techniques are provided for traffic intersection control information to vehicles via V2X communication links. An example method for providing traffic intersection control messages includes receiving vehicle information associated with a plurality of proximate vehicles, generating one or more vehicle groups based on the vehicle information, generating a traffic control plan based at least in part on the one or more vehicle groups, and transmitting one or more traffic intersection control messages to one or more of the plurality of proximate vehicles based at least in part on the traffic control plan.

Abstract: Aspects presented herein may improve the performance of mobile/computer applications. Aspects presented herein may enable mobile/computer applications to differentiate entities that are associated with UEs or entities running the navigations applications, thereby enabling the mobile/computer applications (or their associated servers) to have a more accurate understanding of the conditions surrounding the UEs and their users. In one aspect, a network node obtains first information including at least one feature associated with a plurality of devices. The network node selects a first subset of the plurality of devices for a measurement based on the at least one feature associated with the plurality of devices (or the network node may exclude a second subset of the plurality of devices from the measurement).

Abstract: 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).

Abstract: 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.

Abstract: Method and apparatus for maintaining C-V2X timing (e.g., in platoon scenarios). The apparatus of a slave UE determines a thermal condition of the respective slave UE within a platoon of UEs. The apparatus performs synchronization with a first synchronization source, directly or indirectly, based on the thermal condition of the slave UE. Synchronization is performed directly with the first synchronization source in response to a determination that the thermal condition of the slave UE is below a threshold. Synchronization is performed indirectly with the first synchronization source through a master UE within the platoon of UEs in response to a determination that the thermal condition exceeds a threshold. The apparatus may receive, from a master UE within the platoon of UEs, SLSS to synchronize indirectly to the first synchronization source through the master UE.

Abstract: Method and apparatus for C-V2X synchronization. The apparatus detects an object in an environment that obstructs synchronization with a network. The apparatus transmits, via at least one transceiver, to at least one second wireless device, a message indicating the object that obstructs the synchronization with the network. The apparatus may receive, from a third wireless device, an indication that identifies the object in the environment that obstruct the synchronization with the network. To detect the object in the environment, the apparatus may receive, from a wireless device, an indication that identifies the object in the environment that obstructs the synchronization with the network.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain an indication that a network node is configured to accept a request for the network node to perform network coding for a communication from the UE. The UE may transmit, based at least in part on the UE being within an area associated with the network node, the request for the network node to perform the network coding for the communication. Numerous other aspects are described.

Abstract: 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.
