Abstract: Techniques described herein include utilizing a mobile device as a proxy receiver for a vehicle such that a driver of the vehicle can be presented driving assistance information based on messages received by the mobile device. The mobile device can determine that it is temporally located with the vehicle. If so, the mobile device can be configured to receive messages from other entities (e.g., vehicles, roadside units, traffic signals, and the like) in a vehicle-to-everything network. On reception, the mobile device may determine whether a received data message is relevant to the vehicle. In response to determining that the data message is, in fact, relevant to the vehicle, the mobile device may provide driving assistance information that is generated based at least in part on the information provided in the received data message.

An example method for downloading data on a mobile device includes determining an estimated time of arrival at a station based at least in part on almanac information, generating a data download request based at least in part on the estimated time of arrival at the station, transmitting the data download request, and receiving one or more data packets from the station based on the data download request.

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: In an aspect, a method includes determining, by a processor of a vehicle, that an original equipment manufacturer (OEM) subscription of the vehicle is set to a low capability subscription. The method includes determining, by the processor, that the low capability subscription is unable to access a network at a current location of the vehicle based on the low capability subscription. The method also includes determining, by the processor and based on sensor data received from one or more sensors of the vehicle, a probability of an accident occurring to the vehicle. The method further includes determining, by the processor, that the probability satisfies a threshold. The method includes switching, by the processor, the OEM subscription from the low capability subscription to a high capability subscription.

Abstract: Techniques described herein provide for filtering and prioritizing incoming messages, which can help reduce and smooth out the processing load on components used to process the incoming messages. Filtering techniques may comprise identifying a subset of nearby vehicles from which messages are to be processed, and further calculating remaining delay budgets with regard to the messages to prioritize them for processing. Different techniques for determining a subset of nearby vehicles can be used, and/or remaining delay budgets may be calculated and/or communicated in different ways.

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.

Abstract: Techniques described herein include utilizing a mobile device as a proxy receiver for a vehicle in a V2X environment. In some embodiments, the mobile device may be configured to obtain vehicle and/or occupant metadata and store such data in memory at the mobile device. At a subsequent time, the mobile device may receive a V2X data message from a remote device (e.g., a V2X capable vehicle, another proxy device, a roadside unit, or any suitable device of the V2X environment that is different from the mobile device). The mobile device may process the data message based at least in part on the vehicle metadata and/or occupant metadata and perform one or more operations in response to processing the data message.

Abstract: Techniques described herein include utilizing a mobile device as a proxy receiver and/or transmitter for a vehicle in a V2X network. In some embodiments, the mobile device associated mobile device capabilities may be configured to obtain vehicle capabilities and store such data in memory at the mobile device. The mobile device may obtain any suitable combination of a reception credential and one or more transmission credentials. In some embodiments, the one or more transmission credentials may be generated by a credential authority based at least in part on determining that the vehicle capabilities and mobile device capabilities indicate that the sensor(s) and/or processing resources of the vehicle and/or mobile device meet transmission requirement thresholds for the network. The mobile device may subsequently transmit any suitable data message on behalf of the vehicle using at least one of the transmission credentials.

Abstract: Some methods may involve receiving, at a first node of the health network, encrypted sensor data from one or more sensors. The first node may be in a data communication path between the one or more sensors and other nodes of the health network. The method may involve decrypting, by the first node of the health network, only a portion of the encrypted sensor data, and transmitting the encrypted sensor data from the first node of the health network to a second node of the health network. The first node may be a gateway device. In some examples, the second node may be able to decrypt more of the encrypted sensor data than the first node.

Abstract: A user device and transportation entity, such as a transport vehicle or transport server, perform information exchanges for a transportation service using Device-to-Device (D2D) communications, such as dedicated short-range communication (DSRC), a cellular Vehicle-to-Everything (C-V2X), or a 5G New Radio (NR). The information exchanges, for example, are related to, e.g., logistics and delivery of transportation services. For example, the user device may transmit a transportation request message that includes information elements, such as an identifier, a type of transport device requested, a number of users, requested destination, etc. The transportation entity may transmit a transportation response message accepting or rejecting the request. Additional messages, such as a status request and status of the transportation, as well as messages related to completing the transportation service may be exchanged.
