Abstract: The present disclosure relates to precoding matrix determining methods, devices, and systems. In one example method, a receive end device obtains channel state information (CSI) of a first channel and information about P antenna port groups of a transmit end device. The receive end device determines V orbital angular momentum (OAM) mode groups based on the CSI of the first channel and first OAM modes, determines a first precoding matrix based on the P antenna port groups of the transmit end device and the V OAM mode groups, and sends, to the transmit end device, first indication information indicating the first precoding matrix. The transmit end device receives the first indication information, and determines the first precoding matrix based on the first indication information.

Abstract: This application relates to communication methods and apparatuses. In an example method, a first communication apparatus generates first indication information, and sends the first indication information to a second communication apparatus. The first indication information indicates M orbital angular momentum (OAM) modes jointly supported by the first communication apparatus and the second communication apparatus, where there is a correspondence between N OAM modes in the M OAM modes and a demodulation reference signal (DMRS) port.

Abstract: A method includes sending a first orbital angular momentum (OAM) reference signal in a first beam direction. The first OAM reference signal is used to determine a second beam direction from the first beam direction. The method also includes receiving first indication information. The first indication information includes information about the second beam direction. The method also includes sending a second OAM reference signal in the second beam direction. The second OAM reference signal is used to determine antenna information and a second channel response of the second OAM reference signal. The method also includes receiving second indication information. The second indication information is determined based on the second channel response and the antenna information. The second indication information is used to determine a transmission manner. The transmission manner includes OAM wave transmission, plane wave transmission, or joint transmission of OAM and a plane wave.
