Title:
BASE STATION, MOBILE STATION, AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2007/083567
Kind Code:
A1
Abstract:
A base station performs communication by the orthogonal frequency division
multiplex (OFDM) method with a mobile station by using a predetermined frequency
band in the transmission band. The base station includes means having a center
frequency on the first band raster and transmitting a synchronization channel
at the second band; and allocation means having a center frequency on the first
band raster with respect to the mobile station performing a peripheral search
and allocating a band of the band with equal to or above the second band.
