The invention discloses a channel state information CSI report method and device. A UE receives CSI report information; and the UE parses the CSI report information, and confirms a frequency band, a report type and a report mode corresponding to the CSI report, a CSI process corresponding to the CSI report, one or more combinations of CSI subframe sets and/or cells corresponding to the CSI report, and a CSI report manner. CSI report transmission of the UE is ensured not to be influenced under the condition that partial uplink subframes of the uplink frequency band in an LTE FDD system are occupied.
