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.

Claim (Index 25):
The non-volatile computer readable storage medium according to  claim 24 , further comprising computer program codes which when executed by the processor cause the processor to execute the steps of:\n decoding, based on a quantity Q1+Q2 of bits, a signal that comprises the RI and the indication information and that is in the CSI signal, the decoding obtaining the RI and the indication information, wherein the RI is represented by using Q1 bits, and the indication information is represented by using Q2 bits.
