Summary:A joint channel correction method, an apparatus, and a system are disclosed. The joint channel correction method includes: sending a first joint channel correction instruction to a first RRU; sending a second joint channel correction instruction to a second RRU; receiving a result sent by the second RRU about reception of the first correction reference signal through X2 receive channels in X2 traffic channels; receiving a result sent by the first RRU about reception of the second correction reference signal through X1 receive channels in X1 traffic channels; and obtaining correction compensation coefficients of the X1 traffic channels and/or the X2 traffic channels through calculation. Technical solutions provided by embodiments of the present application help implement channel correction between RRUs without a channel self-correction function.
