摘要： 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.

摘要： The present disclosure relates to feedback methods and apparatuses. In one example method, a first communication apparatus may receive first information. The first information includes at least one of channel state information (CSI) measurement quantity indication information for channel variation calculation, a CSI type and a rule that are for the channel variation calculation, or a feedback suggestion parameter. The feedback suggestion parameter indicates a suggested feedback form. The first information is used to select a second communication apparatus. The first communication apparatus may determine, based on the first information, whether to trigger the second communication apparatus/apparatuses to send a feedback result. Correspondingly, the first communication apparatus receives the feedback result.

摘要： 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.
