Abstract
The methods, devices, and systems discussed herein involve a mobile wireless communication device (WCD) receiving a signal containing an indicator upon entering a first area that is near a potential safety scenario, such as an intersection. In response to receiving the signal, the WCD initiates a Random-Access Channel (RACH) procedure, which triggers initiation of a collision-avoidance procedure. In some examples, the collision-avoidance procedure includes abase station transmitting a safety message that indicates the presence of the mobile WCD. In other examples, the collision-avoidance procedure includes the mobile WCD transmitting a device-to-device (D2D) safety message using D2D resources. In further examples, the collision-avoidance procedure includes the mobile WCD sensing D2D resources in order to detect D2D transmissions from a D2D-capable device.
