摘要： The present invention discloses a method, device and system for configuring codebooks. The method comprises a transmitting end selecting a code word restricted sub-set and informing a receiving end of the code word restricted sub-set, the code word restricted sub-set containing part or all of code words in a first codebook and/or a second codebook; and the receiving end selecting an optimal pre-coded code word from the code word restricted sub-set and informing the transmitting end of an index of the optimal pre-coded code word. By the present invention, code word restriction is implemented in the case of dual codebooks in the LTE-A system such that the calculation complexity is reduced when the receiving end selects the code word, occurrences of the case where the receiving end selects the code word wrongly are decreased, and the signaling structure in the LTE system can be inherited very well.
