Title:
METHOD AND APPARATUS FOR SIMULTANEOUS TRANSMISSION OF DATA AND ENERGY
Document Type and Number:
WIPO Patent Application WO/2023/065856
Kind Code:
A1
Abstract:
The present application provides a method and apparatus for simultaneous transmission of data and energy, relating to the field of communications, and solving the problem of low downlink charging efficiency in a small bandwidth, small subcarrier spacing system. The method comprises: mapping an nth group of information to be sent, among a number N of groups of information to be sent, to a Kth subcarrier, to generate an nth subcarrier vector, n, N, and K being positive integers, 1 ≤ n < N, N ≥ 2, and K ≥ 2; converting the nth subcarrier vector from a frequency domain to a time domain, to generate a superimposed waveform corresponding to the nth group of information to be sent, the superimposed waveform corresponding to the nth group of information to be sent being formed by superimposing K time domain waveforms, and a peak to average power ratio of the superimposed waveform corresponding to the nth group of information to be sent being greater than a peak to average power ratio threshold; sending superimposed waveforms corresponding to each of the N groups of information to be sent, a relative position in a time unit of a main lobe of the superimposed waveform corresponding to the nth group of information to be sent corresponding to a value of the nth group of information to be sent.
