摘要：
The present invention is designed to support smooth mobility of a mobile terminal apparatus between a plurality of local areas that are arranged in a wide area. The present invention includes a wide area base station apparatus (20) that covers a wide area (C1), a local area base station apparatus (30) that covers a local area (C2) arranged in the wide area (C1), and a mobile terminal apparatus (10) that can communicate with the wide area base station apparatus (20) and the local area base station apparatus (30), and is configured to scramble a data signal and a reference signal by a scrambling sequence that is common between a plurality of local areas (C2) in communication between the local area base station apparatus (30) and the mobile terminal apparatus (10).
