1. A multiple Transmit-Receive Points (TRPs) or antenna panels based Channel Quality Indicator (CQI) measurement reporting method, comprising:
determining, by a network side device, for multiple TRPs or antenna panels for coordinated transmission, Channel State Information (CSI) measurement resources used for CQI measurement;
generating, by the network side device, network side configuration information, which is used to indicate the network side device to configure a terminal to perform CQI measurement corresponding to a Time Division Multiplexing (TDM) transmission manner according to the CSI measurement resources, and report CQI measurement results to the network side device after obtaining corresponding CQI measurement results; and
sending, by the network side device, the CSI measurement resources and the network side configuration information to the terminal,
wherein the configuring, by the network side device, the terminal to perform CQI measurement corresponding to the TDM transmission manner according to the CSI measurement resources, comprises: configuring, by the network side device, according to CSI measurement resources configured for each of two TRPs or antenna panels for coordinated transmission, the terminal to jointly calculate a set of CQI values.
