摘要

The disclosure includes embodiments for modifying a vehicle-to-everything (V2X) radio of an ego vehicle that is a connected vehicle. In some embodiments, a method includes analyzing, by a machine learning module executed by a processor, a local dynamic map generated by the ego vehicle to determine schedule data describing a schedule for the ego vehicle to transmit a millimeter wave (mmWave) message to a remote vehicle. The method includes transmitting a V2X message including the schedule data for receipt by the remote vehicle so that the remote vehicle has access to the schedule. The method includes modifying an operation of the V2X radio of the ego vehicle based on the schedule so that the V2X radio transmits the mmWave message to the remote vehicle in compliance with the schedule. The method includes transmitting the mmWave message to the remote vehicle in compliance with the schedule.

說明書

The feedback data 144 includes digital data describing a recommended beam alignment setting that is determined by the server 106 based on the scenario data 140. The feedback data 144 is described below in more detail.

The communication unit 145 transmits and receives data to and from the network 105 or to another communication channel. In some embodiments, the communication unit 145 may include a DSRC transceiver, a DSRC receiver and other hardware or software necessary to make the first endpoint 101 a DSRC-enabled device. For example, the communication unit 145 includes a DSRC antenna configured to broadcast DSRC messages via the network. The DSRC antenna may also transmit BSM messages at a fixed or variable interval (e.g., every 0.1 seconds, at a time interval corresponding to a frequency range from 1.6 Hz to 10 Hz, etc.) that is user configurable.
