Abstract: A communication system includes a first node, a second node, and a third node, and one of these nodes acts as a coordinating node. The coordinating node obtains first information that includes information regarding a candidate beam for the first node and information regarding a candidate beam for the second node. The coordinating node determines beam information of the first node and beam information of the second node based on the first information, where the beam information of the first node indicates a transmit beam for the first node, and the beam information of the second node indicates a receive beam for the second node.

Abstract: This application provides a signal generation method and an apparatus. In the method, a first communication apparatus generates a first signal, and sends the first signal to a second communication apparatus, who receives the first signal, and then demodulates the first signal. A symbol included in the first signal is carried on K+2(M−1) subcarriers. Middle K subcarriers are valid subcarriers, start M−1 subcarriers and last M−1 subcarriers are redundant subcarriers, and a subcarrier spacing between adjacent subcarriers is related to a feature of a time domain pulse used to shape the subcarrier, wherein a width of each of some or all side lobes of a spectrum of the time domain pulse is equal to 1/M of a main lobe width of the time domain pulse, the subcarrier spacing is 1/M of the main lobe width. K is a positive integer, and M is a positive integer greater than 1.

Abstract: In a communication method, a first transmit end receives an equivalent channel ratio corresponding to a second transmit end, and obtains a precoding matrix of the first transmit end based on the equivalent channel ratio corresponding to the second transmit end. When the first transmit end sends a signal by using the obtained precoding matrix, a first target receive end implements interference alignment.

Abstract: This application discloses a data sending method, a data receiving method, and a related apparatus. First phase rotation is performed on modulated data to obtain time domain rotated data. Frequency domain transform is performed on the time domain rotated data to obtain frequency domain data. Second phase rotation is performed on the frequency domain data to obtain frequency domain rotated data. Time domain transform is performed on the frequency domain rotated data to obtain time domain data. The time domain data is sent. Therefore, phase rotation may be separately performed on the modulated data and the frequency domain data based on an SC-FDMA waveform, to reduce a maximum amplitude of the time domain data and reduce a PAPR of the sent time domain data.

Abstract: This application provides communication methods and communications apparatuses. In an example method, a first communications apparatus determines whether a first channel learning model is applicable, where the first channel learning model is used to determine first channel information based on target channel information, and a data amount of the first channel information is less than a data amount of the target channel information. The first communications apparatus sends a first message in response to determining that determining that the first channel learning model is not applicable, where the first message is used to indicate that the first channel learning model is not applicable. According to the example method, the first communications apparatus can determine applicability of the first channel learning model without assistance of a second communications apparatus.
