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: Apparatus, methods, and computer-readable media for facilitating autonomous synchronization are disclosed herein. For example, a UE may be configured to perform an initial synchronization directly to PSCCH and PSSCH when other synchronization sources, such as GNSS, a base station, and/or SLSS, are unavailable. An example method for wireless communication at a user equipment includes receiving a PSCCH. The example method also includes performing an initial synchronization based on the PSCCH. In some examples, the method may also include receiving a PSSCH, and determining a logical subframe number modulo 10 based on the PSSCH. The logical subframe number modulo 10 may correspond to a sequence seed.

Abstract: Certain aspects of the present disclosure provide techniques for determining a cable loss associated with a transmission cable of an apparatus. An example method includes sending, to a radio modem of the apparatus, a request for the radio modem to use a target power when sending one or more signals to the signal compensator device for determining a cable loss associated with a transmission cable communicatively coupling the radio modem with the signal compensator device, receiving, at a signal compensator device of the apparatus, the one or more signals from the radio modem sent using the target power, and determining the cable loss associated with the transmission cable based on the one or more signals.

Abstract: A method of controlling a radio-frequency (RF) transaction region comprises: determining a value of a characteristic associated with an ability of roadside equipment, associated with an RF transaction, to obtain information from a user equipment (UE) in the RF transaction region; determining, based on the value of the characteristic, a value of a parameter affecting the ability of the roadside equipment to obtain the information from the UE in the RF transaction region; and conveying the value of the parameter to the UE to affect transmission of messages from the UE to the roadside equipment.

Abstract: This disclosure discloses various vehicle-to-everything (V2X) wireless communication processes that use switching diversity to improve coverage over that of a single transmit antenna. Switching diversity may be implemented by alternating the transmit antennas according to a certain switching pattern. A V2X device determines a pattern for alternating a plurality of antennas for transmitting data packets. The V2X device selects, based on the pattern, a first antenna of the plurality of antennas, and transmit a first packet of the data packets using the first antenna. The V2X device further select, based on the pattern, a second antenna of the plurality of antennas, and transmit a second packet of the data packets using the second antenna.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE), such as a roadside unit (RSU), located in an area of limited or no global navigation satellite system (GNSS) coverage may circulate sidelink synchronization signal (SLSS) neighbor information, such as in the form of an SLSS neighbors list (SNL). The SLSS neighbor information may include one or more of an index number, an SLSS identifier (ID), a timing source in-coverage flag, an RSU ID, a hop ID, a geographic location, a transmission synchronization offset, a synchronization source, and/or a coordinated universal time (UTC) time.

Abstract: Disclosed are systems and techniques for road usage charging. For example, a vehicle (e.g., using a vehicle computing device (VCD)) can receive an encryption key of a first charging entity and determine a first road usage charge associated with the first charging entity based on a first charge policy. The vehicle can determine a total usage charge (based on the first road usage charge) for road usage (e.g., associated with the first charging entity) and can encrypt the total usage charge based on the encryption key. The vehicle can determine information associated with the total usage charge and can encrypt the information associated with the total usage charge based at least in part on the encryption key. The vehicle can transmit the encrypted total usage charge to a first network entity and can transmit the encrypted information to a second network entity for verifying the encrypted total usage charge.

Abstract: Apparatus, methods, and computer program products for cache building for cryptographic verification that may be used in connection with a V2X communication system are provided. An example method includes receiving, from a second wireless device, at least one V2X message of a plurality of V2X messages, the at least one V2X message being associated with a verification key. The example method further includes determining whether the verification key for the at least one V2X message is a target verification key. The example method further includes determining, if the verification key is the target verification key, to generate an entry in a cache for the verification key. The example method further includes generating, upon determining to generate the entry in the cache, the entry in the cache for the verification key.

Abstract: Methods and devices and systems for implementing the methods for authenticating plaintext and ciphertext in a vehicle-to-everything (V2X) message include generating ciphertext from a plaintext message to be transmitted in a V2X message, generating a hash of the ciphertext and a hash of the plaintext message, generating a digital signature of a concatenation of the hash of the ciphertext and the hash of the plaintext message, and sending to a network node a V2X message that includes the ciphertext, the hash of the plaintext message, and the digital signature. The hash of the plaintext message, and the digital signature may be configured to enable the network node to verify that the V2X endpoint node signed the concatenation.

Abstract: Disclosed are techniques for performing thermal mitigation for one or more devices. For instance, a temperature, humidity, amount of light, and/or other characteristic or factor associated with a vehicle can be obtained. Whether to transition one or more communication functions from the vehicle to a user device can be determined based on the temperature, humidity, etc. In response to a determination to transition the one or more communication functions, the one or more communication functions can be transitioned from a communication unit of the vehicle to a communication unit of the user device.
