The embodiments of the present invention provide a joint channel correction method, apparatus and management device and relate to the technical field of networks. The method includes: obtaining joint uplink channel information of a first transmission point and a second transmission point; receiving a joint Preferred Matrix Index (PMI) fed back by a user equipment; obtaining a phase difference between the second transmission point and the first transmission point according to the PMI and a phase vector obtained on the basis of the uplink channel information; using the phase difference to correct the downlink channel of the second transmission point. By obtaining the phase difference between the second transmission point and the first transmission point and using the phase difference to correct the downlink channel of the second transmission point, the present invention resolves the problem that in the prior art high device cost is disadvantageous for the existing stock devices to support multiple Transmission Point (TP) coherent Joint Transmission Coordinated Multiple Point (JT CoMP), and achieves the effects of implementing multiple TP coherent JT CoMP on the basis of the existing devices and improving the cell transmission performance. |
