BASE STATION APPARATUS AND MOBILE STATION APPARATUS

Title:

BASE STATION APPARATUS AND MOBILE STATION APPARATUS

Document Type and Number:

WIPO Patent Application WO/2007/023524

Kind Code:

A1

Abstract:

A base station apparatus that transmits frames in accordance with a communication format, and a mobile station apparatus that uses the frames to determine the communication format of the base station apparatus, and then performs an adaptive cell search in accordance with the determined communication format. The base station apparatus (100) comprises a plurality of antennas; a transmitting part (150) that transmits frames via the antennas; and a frame forming part (130) that forms, in accordance with the number of antennas to be used for the transmission, frames in which different synchronization sequences (SCH sequences) are arranged. Then, in the mobile station apparatus (200), an RF receiving part (210) receives the frames from the base station apparatus (100); a transmission format/frame timing determining part (240) determines the frame timing and the number of the used antennas; and a scrambling code identifying part (245) extracts, based on the frame timing and the number of the used antennas, the pilot signal from the frames and then uses the extracted pilot signal to identify the base station scrambling code.
