摘要： A method and apparatus for reporting channel state information (CSI) based on a physical uplink shared channel (PUSCH) are used to realize correct reporting of the CSI based on double code books. The method includes the following steps: a reporting mode configuration signaling for the CSI sent from a network side is received, and said reporting mode configuration signaling for the CSI at least carries a designated reporting mode identifier; a first CSI aiming at the whole bandwidth of a system is established according to a reporting type corresponding to said reporting mode identifier; the whole bandwidth of the system is divided into at least two frequency band subclasses, and a second CSI aiming at a designated frequency band subclass is established according to the reporting type corresponding to said reporting mode identifier; and when a reporting indication signaling sent from the network side is received, said first CSI and said second CSI are transmitted to the network side. Therefore, when a user equipment (UE) reports the CSI, a long-term/wideband CSI and a short-term/frequency selective CSI could be considered comprehensively, then a two-level feedback mechanism based on the PUSCH double code books is realized.
