    Abstract: Provided are a method for channel information feedback in a multi-antenna system, and a terminal. The method comprises: a terminal receives CSI-RSs of M ports sent by a base station, and performs estimation according to the CSI-RSs to obtain M-dimensional downlink channel information; the terminal uses a transformation function Fk to perform a linear transformation on the M-dimensional downlink channel information, and obtains Nk-dimensional kth type channels, wherein k is greater than or equal to 1 and less than or equal to K, M≥Nk, and K≥1; the terminal uses a preset Nk-dimensional codebook to respectively perform channel information quantisation on the kth type channels, and determines a corresponding precoding matrix and precoding matrix indicator information (PMIk); the terminal selects S type channels from within K type channels, and feeds index numbers of the selected channels and corresponding PMI back to the base station.

    Abstract: The embodiments of the invention provide a method of configuring a channel state information reference signal (CSI-RS) transmitted on a pilot and a device utilizing the same. The method includes: a base station generates a signaling including configuration information of a CSI-RS; and the base station transmits the signaling including the configuration information of the CSI-RS; wherein the configuration information includes a CSI-RS port number, CSI-RS resource patterns and a CSI-RS subframe configuration; the CSI-RS resource patterns include at least one of the following: CSI-RS resource patterns transmitted on a normal downlink subframe and CSI-RS resource patterns transmitted on a downlink pilot time slot (DwPTS). The CSI-RS subframe configuration includes a CSI-RS subframe configuration transmitted on both the DwPTS and the normal downlink subframe. The embodiments resolve a complicated problem of transmitting CSI-RS in DwPTS in a CSI-RS transmission scenario, reducing complexity of transmitting CSI-RS in DwPTS.

    Abstract: A method for channel information feedback, a base station and a device, the method includes: a terminal performs a channel measurement, constructs an information matrix used for representing channel information according to a preset function, determines optimal channel parameters and feeds back the channel parameters to a base station; and the base station constructs quantization information of a characteristic vector of a channel matrix according to the received channel parameters and the channel matrix. In the technical solution provided by the embodiment of the present document, since the most essential characteristic of a dual-polarized channel, i.e., information u that represents a multipath direction, is matched in the channel matrix, channel information feedback with the lowest cost is implemented, and compared with the existing codebook feedback solution, on the basis that feedback precision is satisfied, the feedback overhead is obviously reduced, terminal implementation complexity is reduced and feedback efficiency is improved.
