Abstract: A channel state information sending method, a channel state information receiving method, and a device are disclosed, to reduce resource overheads required when a terminal device feeds back CSI to a network device in a scenario of a high precision codebook-based precoding matrix. The method includes: determining, by a terminal device, a precoding matrix W; sending, by the terminal device, a signal including CSI to a network device; obtaining, by the network device, an RI and indication information based on the signal including the CSI; obtaining, by the network device, a PMI2 based on the RI and the indication information; and determining, by the network device, the precoding matrix W based on the rank indicator RI and the second precoding matrix indicator PMI2.

Abstract: The present disclosure provide a method and an apparatus for transmitting channel state information. A terminal device receives a reference signal from a network device, obtains a precoding matrix based on the reference signal. The terminal device determines first amplitude information and second amplitude information of the precoding matrix. The first amplitude information is used to indicate amplitude quantization information of a wideband, and the second amplitude information is used to indicate amplitude quantization information of N subbands of the wideband. The terminal device sends the first amplitude information and the second amplitude information to the network device.

Abstract: A channel information sending method, a data sending method, and a device are provided, to improve feedback precision of a precoding matrix. A first device includes: a receiving module, configured to receive a reference signal; a processing module, configured to measure the reference signal to obtain first channel information and second channel information; and a sending module, configured to send the first channel information and the second channel information. When generating the precoding matrix, the second device may perform weighted combination on M first vectors based on the weighted combination factor indicated by the received second channel information, instead of selecting only one eigenvector from a plurality of eigenvectors, so that the generated precoding matrix is more precise.
