Electronic device with adjustable wireless circuitry

摘要

An electronic device may be provided with wireless circuitry. Control circuitry may be used to adjust the wireless circuitry. The wireless circuitry may include antennas that are tuned, adjustable impedance matching circuitry, antenna port selection circuitry, and adjustable transceiver circuitry. Wireless circuit adjustments may be made by ascertaining a current usage scenario for the electronic device based on sensor data, information from cellular base station equipment or other external equipment, signal-to-noise ratio information or other signal information, antenna impedance measurements, and other information about the operation of the electronic device.

主权项

1. An electronic device that wirelessly communicates with external equipment, comprising:
an antenna; wireless radio-frequency transceiver circuitry that transmits and receives radio-frequency signals through the antenna, wherein the wireless radio-frequency transceiver circuitry comprises multiple transceivers; a tunable component that tunes the antenna; and control circuitry that tunes the tunable component to tune the antenna based on information received from the external equipment, wherein the control circuitry comprises baseband circuitry configured to generate receive signal strength performance metric values for each of the multiple transceivers, and the control circuitry is configured to generate a weighted summation of the generated receive signal strength performance metric values and is configured to adjust the wireless radio-frequency transceiver circuitry based on the weighted summation.
