Vehicle including dynamic sensor-based precoding for millimeter wave communication

A system of a vehicle that is a transmitter of a millimeter wave message which is transmitted to a receiver of the millimeter wave message, the system comprising:

• a millimeter wave radio;
• a perception sensor;
• and
• an onboard vehicle computer system that is communicatively coupled to the millimeter wave radio and the perception sensor, the onboard vehicle computer system including a non-transitory memory storing computer code which, when executed by the onboard vehicle computer system causes the onboard vehicle computer system to:
• measure, by the perception sensor, sensor data describing one or more locations of one or more objects that are proximate to the receiver and the transmitter;
• determine, based on the sensor data, angle data describing one or more angles of arrival for the one or more objects and one or more angels of departure for the one or more objects;
• generate, based on one or more of the sensor data and the angle data, propagation data describing (1) a list of paths between the transmitter and the receiver and (2) channel gains for each path included in the list of paths;
• determine, based on one or more of the sensor data and the propagation data, a plurality of channels for successfully transmitting the millimeter wave message to the receiver;
• and
• transmit, by the millimeter wave radio, the millimeter wave message to the receiver using the plurality of channels on a band of spectrum between 30 gigahertz and 300 gigahertz.

A computer program product comprising a non-transitory memory of an electronic control unit of a vehicle storing computer-executable code that, when executed by the electronic control unit, causes the electronic control unit to:

• measure, by a perception sensor, sensor data describing one or more locations of one or more objects that are proximate to a receiver and a transmitter of a millimeter wave message, wherein the vehicle is the transmitter of the millimeter wave message;
• determine, based on the sensor data, angle data describing one or more angles of arrival for the one or more objects and one or more angels of departure for the one or more objects;
• generate, based on one or more of the sensor data and the angle data, propagation data describing (1) a list of paths between the transmitter and the receiver and (2) channel gains for each path included in the list of paths;
• determine, based on one or more of the sensor data and the propagation data, a plurality of channels for successfully transmitting the millimeter wave message to the receiver;
• and
• transmit the millimeter wave message to the receiver using the plurality of channels on a band of spectrum between 30 gigahertz and 300 gigahertz.
