    • The present invention discloses a method for Multiple Input Multiple Output (MIMO) channel information feedback, and the method includes: a terminal selecting part of column vectors for MIMO system feedback from a codebook matrix W corresponding to a Precoding Matrix Indicator (PMI) and marking the selected part of column vectors as Wpart; the terminal determining information O which represents high-precision vector quantification information of MIMO along with the part of column vectors Wpart according to a common representation relationship F, and feeding back the information O to a base station. The present invention also discloses a terminal and a base station which support MIMO. The present invention achieves high-precision and low-overhead channel information feedback and can well support multiple vector feedback needed by high rank (more layer multiplexing) MIMO transmission and high-precision feedback needed by low rank MIMO transmission simultaneously.

    • The present invention discloses a method and terminal for feeding back channel status information, including: when the channel status information is fed back on the physical uplink control channel, code words contained in the used codebook CPUCCH (r) with a layer number or rank being r is a subset of the code words contained in the codebook CPUSCH (r) with a layer number or rank being r in the overall codebook defined in the LTE-A; wherein, the CPUCCH (r) is a single codebook or a single codebook equivalent to dual codebooks; and the CPUSCH (r) is a single codebook or a single codebook equivalent to the dual codebooks; and the single codebook equivalent to the dual codebooks means that the actually used codebook is an actually defined single codebook, however, 2 pre-coding matrix identifiers are required to determine the codebook of the code words therein for an established r. The method described by the present invention can ensure the precision of the PMI feedback under the limited overhead, make the CSI feedback on the PUCCH still be able to more effectively support the pre-coding technology and have good compatibility with the feedback on the PUSCH.
