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: 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: A communication device mounted on a vehicle, e.g., On-Board Unit (OBU), communicates collision related information to other road entities, e.g., other vehicles or roadside units (RSUs) or a server, after a collision is detected. The OBU may temporarily store basic safety messages (BSMs) (and optionally sensor data) for a predesignated number of seconds before discarding the BSMs (and optionally sensor data) on a continuing basis. When a collision is detected, the OBU sends a report, e.g., to a server, with the stored BSMs (and optionally sensor data) to a server. After a collision detection, the OBU may send a request to other vehicles to upload relevant collision related information. Additionally, if a first vehicle detects the collision of a second vehicle, the first vehicle may communicate collision related information to other entities and a server.
