Abstract (en)
[origin: CN111183601A] An electronic device that provides modified electrical signals is described. An interface circuit in the electronic device may provide electrical signals for an antenna module, which may be coupled tothe interface circuit by a cable, and the electrical signals may correspond to or may specify an output transmit-power level at the interface circuit. Then, the interface circuit may receive feedbackabout an input transmit-power level at the antenna module. Based on the feedback, a data rate and/or a modulation and coding scheme, the interface circuit may provide the modified electrical signalsfor the antenna module, where the modified electrical signals correspond to a modified output transmit-power level at the interface circuit. In some embodiments, the feedback is provided by repurposing, during a different operating mode, signal lines that otherwise specify an antenna pattern.
