ABSTRACT:
Provided are an apparatus and a method for acquiring a code group that is used for a mobile communication terminal to acquire a scrambling code for identification of a base station. The present invention compares a part of slot values in code groups of the secondary synchronization channel transmitted to a mobile communication terminal from a base station with a part of code groups already known and, when there is a code group having a value higher than a predetermined value, reads code groups having the same pattern as that of the code group having a value higher than the predetermined value, which are previously stored in a predetermined storage. Then, the present invention excludes the read code groups from operations to reduce the quantity of unnecessary operations.
