AI Technical Summary

Problems solved by technology

[0004] The current NR downlink multi-cell detection method usually detects multiple cells at one time in a section of baseband received data, and the effect is not good when the same-channel interference is severe and the signal-to-noise ratio is bad. Often only the strongest cell can be detected, and when the cell is detected It will correlate with the entire SSS sequence, and it is very time-consuming and inefficient to execute in a serial system
