  • Patent number: 11438033
    Abstract: In 5G/6G wireless networks, user devices and base stations may adjust their transmission power according to the distance to the recipient, and thereby provide sufficient reception without wasting energy or generating interference. User devices can determine their own location by GPS, for example, and transmit that data to the base station so that the base station can adjust its downlink power accordingly. Likewise. base stations can transmit their location coordinates to user devices in, for example, a system information message. Sidelink, or V2V and V2X, messages can likewise be power-adjusted after user devices exchange their location coordinates. Mobile user devices can also indicate their speed and direction of travel, so that the base station or other user devices can calculate the changing distance and compensate power accordingly.

  • Patent number: 11424787
    Abstract: Base stations and user devices can transmit 5G and 6G messages with a wide range of transmission power levels. Selecting the appropriate power level for each message is a complex problem, dependent on the distance to the recipient, the background noise and interference level, priority, and many other conflicting factors. To provide an objective recommendation of the transmitter power level, an artificial intelligence model may be trained, using actual network and message parameters, to accurately predict the subsequent network performance versus power level. Then, a practical algorithm may be derived from the trained AI model, and used by base stations and user devices to select an appropriate transmission power level according to current network conditions and message properties. Use of an appropriate transmission power level for each message may reduce message faults, enhance reliability, mitigate external noise and interference, and save energy especially for battery-operated user devices.
