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.

Claim (Index 11):
A channel state information (CSI) measurement and feedback method, comprising:\n sending, by a base station, a reference signal to a terminal; and receiving, by the base station, first CSI that carries a target index and that is obtained by the terminal by performing channel measurement based on the reference signal, wherein: the target index is a first joint index, and the first joint index is an index jointly generated based on a first precoding matrix indicator PMI and a second PMI; or the target index is a second joint index, and the second joint index is an index jointly generated based on a rank indicator RI, the first PMI, and the second PMI; or the target index is the first PMI and the second PMI; or the target index is a third joint index and the second PMI, and the third joint index is an index jointly generated based on the first PMI and the RI; or the target index is a fourth joint index and the first PMI, the fourth joint index is an index jointly generated based on the second PMI and the RI, the first PMI indicates an index of a codeword in a first dimension in W1, and the second PMI indicates an index of a codeword in a second dimension in W1.
