Claim Text:
1. An antenna calibration method, wherein the method comprises: a user equipment performing downlink channel measurement and determining a downlink channel matrix; the user equipment determining a first weight matrix for antenna calibration based on the downlink channel matrix; and the user equipment notifying the network side of the determined first weight matrix; wherein the network-side apparatus receives one first weight matrix; and the network-side apparatus determines the calibration coefficients by the equation of: wherein E represents the determined calibration coefficients; G represents a diagonal matrix built from the first weight matrix; N represents the number of calibration pilot ports; or the network-side apparatus receives multiple first weight matrices; and the network-side apparatus determines the calibration coefficients in the equation of: wherein E represents the determined calibration coefficient; G represents diagonal matrices built from the first weight matrices.
