Abstract: In vehicle-to-vehicle (V2V) or vehicle-to-everything (V2X) communication, the vehicle may wirelessly transmit a signal. However, transmission of a signal using a fixed transmit power may not be desirable. The transmit power should be adjusted based on various factors such as a vehicle speed and a priority level of the vehicle. The apparatus may be a device capable of wireless communication, and may be in a vehicle. The device determines one or more parameters associated with a vehicle including the device, the parameter including at least one of a speed of the vehicle or a priority level of the vehicle. The device sets a transmit power of the device based on the one or more parameters. The device transmits a message via wireless communication using the set transmit power.
