Wireless communication systems and methods related to signaling line-of-sight (LOS) vehicle information for improving vehicle positioning accuracy are provided. A first vehicle receives, via a sensor, sensor data indicating a line-of-sight (LOS) vehicle. The first vehicle receives, via a wireless communication device, one or more ranging signals. The first vehicle determines that a first ranging signal of the one or more ranging signals is transmitted by the LOS vehicle. The first vehicle determines a position of the LOS vehicle based on at least the sensor data and the first ranging signal. Other aspects, embodiments, and features are also claimed and described.
