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.
