Problems solved by technology

However, due to some parameter deviations among the antenna arrays of multiple different base stations, the realized downlink channel for CoMP transmission is not the original downlink transmission channel
If the base station directly uses these channel state information to design precoding vectors or matrices for downlink data transmission, the performance gain of coordinated multi-point transmission will drop significantly

Abstract

The invention relates to a method for calibrating bias of an antenna array of a first base station relative to the antenna array of a second base station in the first base station of a wireless communication network. The method comprises the following steps: a complete parameter bias range is divided into multiple parts according to requirements for calibration precision, and one characteristic value is specified for each part; in a first cycle, compensation is performed on uplink channel state information according to a preset order and the characteristic value specified for one part among the multiple parts; a pre-coding vector or matrix used for downlink data transmission is designed according to a compensation result so as to pre-code downlink data, and then the downlink data are sent to a user device collaboratively with the second base station; and whether all parts of the parameter bias range are traversed is judged, and if the judgment result is no, the aforementioned steps are executed again; and if the judgment result is yes, the first cycle is ended.

Description

technical field [0001] The invention relates to a wireless heterogeneous communication network, in particular to a method for optimizing wireless link monitoring window parameters in the wireless communication network. Background technique [0002] In a space-division multiplexing system, multiple cells perform downlink transmission in a coordinated manner, which can limit multi-user interference (Multi-User Interference: MUI) to the coordinated The original inter-cell interference channel is transformed into the user's effective channel, so the coordinated multi-point transmission scheme can obviously improve the performance of the cellular system. In the time division multiplexing system, the performance gain brought by the downlink multi-point coordinated transmission can help improve the accuracy of the channel state information by utilizing the channel reciprocity of the system. [0003] Although there is some RF parameter mismatch between the base station and UE side,...
