    Abstract: Disclosed in embodiments of the present application are a measurement reporting method and apparatus. The method comprises: determining, according to a configuration of a network device, a QCL-TypeD parameter and a measurement set when each channel state indication reference signal (CSI-RS) group is used for measurement; and measuring the measurement set on the basis of the QCL-TypeD parameter, and determining N groups of measurement report values, N being a positive integer not less than 1. According to the method provided in the embodiments of the present application, the terminal may report N groups of measurement results when a plurality of TRPs are transmitted by a terminal, which facilitates the network device to provide a suitable multi-TRP related transmission scheme for the terminal according to the measurement report values.
