Abstract: This application provides a communication method and apparatus. According to the method, a first terminal apparatus can determine, based on second information, information that is in first demodulation information and second demodulation information and that is used to demodulate a first data stream, and determine information that is used to demodulate a second data stream. The first data stream is a common stream, and the second data stream is a private stream of the first terminal apparatus. The first terminal apparatus may first demodulate, based on the information that is used to demodulate the first data stream, a signal received by the first terminal apparatus on a first resource, to obtain the first data stream, and then may obtain the second data stream based on the first data stream, the information that is used to demodulate the second data stream, and the signal received on the first resource.

Abstract: A wireless charging apparatus of a wireless charging system obtains, in a charging period, channel information of a transmission channel and a waveform parameter used to indicate a waveform of an electromagnetic wave signal; generates a target electromagnetic wave signal based on the channel information and the waveform parameter; and sends the target electromagnetic wave signal to a to-be-charged device through the transmission channel. The channel information includes signal attenuation and a transmission delay that are of an electromagnetic wave signal transmitted through the transmission channel. The to-be-charged device converts the received target electromagnetic wave signal into a direct current signal, and performs charging based on the direct current signal. The target electromagnetic wave signal determined by the wireless charging apparatus can adapt to channel transmission.
