| Zusammenfassung: | Disclosed is a channel state information acquisition method. The method comprises: selecting a first-type precoding matrix index (PMI) for each layer, and selecting the optimal second-type PMI for each layer according to the first-type PMI of each layer and a second-type PMI set and in accordance with a pre-set criterion; selecting the optimal first-type PMI for each layer according to the optimal second-type PMI of each layer and a first-type PMI set and in accordance with the pre-set criterion; and selecting a first-type PMI and a second-type PMI best matching a current channel from the optimal first-type PMI and the optimal second-type PMI of each layer in accordance with the pre-set criterion, and taking a layer number corresponding to the best matched first-type PMI and second-type PMI as a rank indicator (RI) of a channel matrix. Also disclosed at the same time are a channel state information acquisition apparatus and a storage medium.
