    摘要: The disclosure provides a method and terminal for feeding back channel state information. The method comprises: a UE determining channel state information comprising a first type of PMI and a second type of PMI, wherein the first type of PMI is used for indicating an index of a first precoding matrix in a first precoding codebook, the first precoding matrix is used for mapping channel information of a wideband and/or long-term channel, the second PMI is used for indicating an index of a second precoding matrix in a second precoding codebook, the second precoding matrix is used for mapping channel information of a subband and/or short-term channel; the UE feeding back the channel state information on a PUSCH. The disclosure enables a base station to dynamically select SU-MIMO or MU-MIMO transmission according to the practical channel condition so as to effectively improve the system performance.
