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