Abstract
A first user equipment (UE) may transmit a first ranging message. A second UE may receive the first ranging message. The second UE may calculate a carrier frequency offset (CFO) based on the ranging message. The second UE may transmit a response message comprising control information to modify a transmission protocol. The transmission of the response message may be in response to the calculated CFO being greater than or equal to a threshold value. The calculated CFO may indicate a possible security vulnerability between the first UE and the second UE. The first UE may receive the response message including control information to modify the transmission protocol after the transmission of the first ranging message. The first UE may then transmit a second ranging message based on the control information. The second ranging message may prevent, or mitigate, the detected possible security vulnerability.
