Before describing the channel state information transmission method provided by the embodiment of the present invention in detail, a codebook in the related art is briefly described.
In a New Radio (NR) system with a fifth Generation (5th Generation, 5G), a terminal device reports a Type ii codebook for characterizing CSI to a network device. The Type II codebook is independently coded in a frequency domain (namely each sub-band); due to the fact that the space quantization precision of the Type II codebook is high, the terminal device needs to feed back a large amount of channel information to the network device, a large amount of network resources are occupied, and network overhead is increased.
The Type II codebook is represented by the following formula:

In the related art, when the network device configures the terminal device to adopt the first of the two schemes of the bit width of the SCI, in some scenes, the bit width of the SCI adopts the first scheme, compared with the second scheme, the cost of the CSI fed back to the network device by the terminal device is small; however, in other scenarios, the bit width of the SCI is larger in the first scheme than in the second scheme, and the overhead of CSI fed back to the network device by the terminal device is larger.
