Abstract: 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.

Abstract: A method for mapping downlink dedicated pilots to resource elements in an Extended Cyclic Prefix frame structure, applied in a long term evolution system, includes the following steps: the first downlink dedicated pilot of each port is mapped to the specific position of a physical resource block; other downlink dedicated pilots of the port are mapping-processed according to the time-domain interval, frequency-domain interval and a preset regulation; the time-domain interval is two or three OFDM symbols, and the frequency-domain interval is two subcarriers of the same time domain. By defining the positions of pilots in the physical resource block, downlink dedicated pilots can obtain the information of all channels when a base station uses a beamforming of more than four antennas. Making the channel information obtained by dedicated pilots contain the real channel information and the process-weight-value of a beamforming, a UE does not need to obtain the transmission-weight-value of a beamforming, thereby avoiding the feedback overhead of beamforming weight-values.
