Claim:
1. A method for reporting multipoint channel state information, wherein the method comprises the operations of: configuring, by a network side device, one or more pairs of reference signal resources and report modes for a user equipment; and receiving, by the network side device, channel state information according to the pairs of reference signal resources reported by the user equipment respectively with corresponding report modes; wherein the pair of reference signal resources includes one downlink channel measurement reference signal resource and one downlink interference measurement reference signal resource, and the downlink channel measurement reference signal resource is particularly a reference signal resource configured by the network side device for the user equipment to measure a downlink channel of a transmission point, and the downlink interference measurement reference signal resource is particularly a reference signal resource configured by the network side device for the user equipment to measure interference under an interference assumption; wherein configuring, by the network side device, the one or more pairs of reference signal resources for the user equipment particularly comprises: configuring, by the network side device, the one or more pairs of reference signal resource for the user equipment; and configuring, by the network side device, a corresponding report mode respectively for each pair of reference signal resources configured for the user equipment; wherein configuring, by the network side device, the one or more pairs of reference signal resources for the user equipment particularly comprises: numbering respectively, by the network side device, the respective reference signal resources for measuring downlink channels of the transmission points, and the respective reference signal resources for measuring interference under different interference assumptions, configured by the network side device for the user equipment; and transmitting, by the network side device, pairs of numbers composed of the numbers of the downlink channel measurement reference signal resources and the numbers of the downlink interference measurement reference signal resources included in the one or more pairs of reference signal resources to be configured for the user equipment to the user equipment; or combining, by the network side device, in pairs respectively the respective reference signal resources for measuring downlink channels of the transmission points, and the respective reference signal resources for measuring interference under different interference assumptions, configured by the network side device for the user equipment and numbering the respective combinations respectively; and transmitting, by the network side device, the numbers corresponding to the one or more pairs of reference signal resources to be configured for the user equipment respectively to the user equipment.
