Abstract
A wireless energy charging method and a communication apparatus is described. A terminal device sends a first signal to a network device, and the network device obtains the first signal, and sends at least one energy charging signal, so that the terminal device obtains energy from the at least one energy charging signal. The first signal includes a first modulation symbol sequence, the energy charging signal includes a second modulation symbol sequence, and the second modulation symbol sequence is obtained by conjugating at least one modulation symbol in the first modulation symbol sequence. The network device uses the second modulation symbol sequence as a modulation symbol of the energy charging signal.
