Abstract:
Embodiments of the present invention provide a CSI measurement and feedback method and apparatus. In some embodiments, a terminal receives a reference signal sent by a base station, and the terminal performs channel measurement based on the reference signal, to obtain first CSI carrying a target index I1. Different cases of the target index exist. The terminal sends the first CSI.
