  • Publication number: 20210146974
    Abstract: A system for railway applications using beamforming transmission in a millimeter wave spectrum between antennas of a Communications Based Train Control (CBTC) system and devices in an environment. Performing a beam training with a target device of the devices located in the environment to measure beam signal values and environmental responses for different beams transmitted over the different beam angles using control circuitry connected with the antennas. Control circuitry selects, in response to the beam training, at least one dominant angle for a beamforming communication with the target device. Access stored fingerprinting data that includes values indicative of link attributes associated with beam signal measurements with states of devices and states of environments. Estimating from the mapping stored fingerprinting data, a state of the target device and/or a state of the environment, corresponding to environmental responses for different beams estimated during the beam training.
