Title:
ENERGY CHARGING METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/045835
Kind Code:
A1
Abstract:
An energy charging method and apparatus, relating to the technical field of communications, and capable of improving the energy charging efficiency and the energy charging coverage range. The method may comprise: a first device sends an energy charging signal and a carrier signal to a second device, wherein the energy charging signal is used for providing energy for the second device; the carrier signal is used for providing a carrier for the second device; the peak-to-average power ratio of the energy charging signal is greater than that of the carrier signal, and/or the frequency domain bandwidth occupied by the energy charging signal is greater than or equal to that occupied by the carrier signal, and/or the sending duration of the energy charging signal is greater than or equal to a first duration.
