摘要
The invention relates to a method, in a first base station (110) of a wireless communication network, of calibrating an offset of an antenna array of the first base station relative to an antenna array of a second base station (120) in the wireless communication network, the method including the steps of: dividing a whole parameter offset range into a plurality of segments (S211) according to the requirement of calibration precision and assigning a feature value for each segment; compensating uplink channel state information according to the feature value assigned to one of the plurality of segments in a predetermined order in a first cycle (S411); designing a pre-coding vector or matrix for downlink data transmission according to a compensation result (S413), pre-coding downlink data and subsequently transmitting the downlink data to a user equipment cooperatively with the second base station (S414, S423); and judging whether all the segments of the parameter offset range have been traversed (S415), and if a judgment result is negative, then repeating the foregoing steps; or if the judgment result is positive, then ending the first cycle (S415).
