USER EQUIPMENT, INITIAL CELL SEARCHING METHOD AND APPARATUS THEREOF

摘要

An initial cell searching method is provided. The method includes: receiving at least one frame data sequence including synchronization channel signals; performing a correlation process between all synchronization sequences stored in the user equipment and the received data sequence to obtain correlation sequences, and calculating on each of the correlation sequences to obtain corresponding correlation power sequences; searching the highest peak and the secondary peak for each of the correlation power sequences, and recording the highest peak and its corresponding position and the secondary peak and its corresponding position; and determining a target cell ID based on a first target sequence, wherein the first target sequence corresponds to a synchronization sequence corresponding to a correlation power sequence of which the relative distance between the corresponding position of the highest peak and the corresponding position of the secondary peak meets a predetermined condition, and the highest peak is the maximum one.
