The present invention provides a channel transmission method, device, network side equipment and terminal, the method comprising: sending a PDCCH to a first terminal, the CRC of the DCI of the PDCCH is scrambled by the first RNTI of the first terminal, the The initialization value of the scrambling sequence generator of the PDSCH scheduled by PDCCH is determined by the second RNTI or the third parameter; wherein, the second RNTI or the third parameter is different from the first RNTI, and the second RNTI or the The third parameter is the shared parameter of the first terminal and at least one other terminal; in the embodiment of the present invention, different terminals independently detect their own PDCCHs, and different PDCCHs schedule the same PDSCH resources, so that multiple terminals can jointly While detecting the same physical resource, each terminal can also use the PUCCH resource indicated by its own PDCCH to perform feedback.
