AI Technical Summary
In a multi-input and multiple-output (MIMO) system, changes in antenna characteristics lead to inter-subcarrier interference (ICI), affecting the accuracy of terminal channel measurements and reducing the demodulation performance of the receiver.
The base station configures the same number of channel status information reference signals (CSI-RS) based on the number of antenna characteristics reported by the terminal, so that the terminal can receive the CSI-RS using the antenna characteristics corresponding to the CSI-RS during the channel measurement process, thereby accurately estimating ICI interference.
Through this method, the terminal can obtain more accurate channel measurement results, improve the demodulation performance of the receiver, and enhance the accuracy of channel measurement.
