摘要： A method and device for sending an aggregated CQI are provided by the disclosure. The method includes a terminal side receiving CSI-RS configuration information and/or interference measurement information sent from a base station side, the terminal side determining a sending sequence of aggregated CQI of each aggregated CSI-RS configuration resource and/or interference measurement resource according to a receiving sequence of the CSI-RS configuration information and/or interference measurement information, wherein each aggregated CSI-RS configuration resource and/or interference measurement resource is aggregated of at least one configuration CSI-RS configuration resource and/or interference measurement resource corresponding to the CSI-RS configuration information and/or interference measurement information, the terminal side sending the aggregated CQI to the base station according to the sending sequence. The disclosure resolves the problem in related art that the base station side cannot acquire the channel state of the terminal side accurately due to the fact that the base station side cannot acquire the CSI-RS configuration resource and/or interference measurement resource fed back by the terminal side corresponding to the aggregated CQI, thereby the interference between cells is reduced, and the throughput of system is improved.
