FIELD: radio engineering, communication.SUBSTANCE: invention relates to communication systems. The invention provides a method for reporting channel state information which includes: an eNB (eNodeB) indicating UE to simultaneously feedback CSI (channel state information) reporting of one or more component carriers; the UE simultaneously feeds back the CSI reporting of one or more component carriers according to the indication of eNB. The invention also provides an eNB, which is configured to: indicate UE to simultaneously feedback CSI reporting of one or more component carriers.EFFECT: invention solves the problem how the UE performs channel state information reporting for multiple (downlink) component carriers in a LTE-A system, which can not only ensure the reliability of transmitting channel state information but also reduce the feedback delay of channel state information as much as possible.34 cl, 2 dwg, 3 tbl |
