| titleOfInvention | Multi-antenna channel codebook feedback method and apparatus in mimo system |
| abstract | The present invention relates to a multi-antenna channel codebook feedback method and apparatus in a multiple input multiple output (MIMO) system. In an embodiment, a multi-antenna channel feedback method applied in a MIMO system is provided, comprising: detecting a downlink multi-antenna channel; determining a rank according to a result of detecting the downlink multi-antenna channel, and selecting, based on a pre-determined rule, a codeword from a pre-determined codebook corresponding to the rank; and feeding back an index of the selected codeword and the rank, any codeword in the pre-determined codebook being a product of a first matrix indicating long-term broadband channel information and a second matrix indicating short-term narrowband channel information. In the technical solutions of the present invention, for MIMO multi-antenna channel feedback, finer beam selection and multiple vectors in a discrete Fourier form are implemented, and various antenna configurations comprising a closely-arranged cross-polarized linear array, a sparsely-arranged cross-polarized linear array, and a uniform linear array are supported. |
