Abstract: A PMI feedback method for multi-TRP transmission, a terminal, and a network-side device are provided. The method includes: determining, by a terminal based on target parameters configured by a network side for a plurality of TRPs permitting joint transmission, an orthogonal beam group set corresponding to each TRP; selecting, based on channel information of each TRP, a target orthogonal beam group corresponding to the TRP from the orthogonal beam group set corresponding to the TRP, and selecting a predetermined quantity of target orthogonal beams corresponding to the TRP from the target orthogonal beam group; determining a first feedback parameter for feeding back target orthogonal beam groups corresponding to the plurality of TRPs and a second feedback parameter for feeding back the predetermined quantity of target orthogonal beams; and sending, by the terminal, a PMI parameter, where the PMI parameter includes the first feedback parameter and the second feedback parameter.
