    • The present invention provides a method and device for obtaining precoding matrix. A network apparatus comprises a plurality of groups of cross-polarized linear array antennas. The method comprises: obtaining first channel indicating information indicating a first code word; obtaining second channel indicating information indicating a second code word; determining the precoding matrix, according to the first channel indicating information and the second channel indicating information, the first code word and/or the second code word comprises phase shifts and/or amplitude differences among the plurality of groups of cross-polarized linear array antennas. Since the first code word and the second code word for determining the precoding matrix by the network apparatus comprise phase shifts and amplitude differences among cross-polarized linear array antennas, the phase shifts and amplitude differences among cross-polarized linear array antennas are considered when the network apparatus sends downlink data according to the precoding matrix, so as to be able to improve the receiving quality of the sent data, thereby improving the system performance effectively.

    • The invention proposes a technical scheme (called as explicit feedback (used for feeding the information of downlink channels back to a base station at the user terminal of a wireless communication system, and a technical scheme for precoding the data transmitted to the user terminal based on the information of downlink channels feed back by the user terminal in the base station. The user terminal determines an approximately equivalent matrix of the transmission matrix of downlink channel, based on the transmission matrix of downlink channel, the number of downlink data streams, the spatial correlation matrix of multiple transmitting antennas in the base station and a predetermined codebook; then feeds the information concerning the approximately equivalent matrix back to the base station. The base station recovers the approximately equivalent matrix based on the information concerning the approximately equivalent matrix fed back from the user terminal, and precodes the downlink data transmitted to the user terminal by using the approximately equivalent matrix.
