AERIAL CALIBRATION METHOD, SYSTEM AND DEVICE |
摘要 |
An embodiment of the present invention relates to the technical field of wireless communications, in particular to an aerial calibration method, system and device. In the prior art, an air interface calibration method involving a user equipment (UE) requires the UE to feed back a channel coefficient, and a channel coefficient direct quantization method occupies a great deal of uplink overhead and reduces system efficiency. The present invention solves the above problem. The method in the embodiment of the present invention comprises: the UE measures a downlink channel and determines a downlink channel matrix; the UE determines a first weighting matrix for aerial calibration according to the downlink channel matrix; the UE notifies a network side of the determined first weighting matrix. In the embodiment of the present invention, a UE decomposes the characteristic value of the downlink channel matrix, or reports the identifier corresponding to the first weighting matrix to the network side device, thus reducing the occupied uplink overhead and improving system efficiency. |
