| 20090135802 | SCALABLE BANDWIDTH SYSTEM, RADIO BASE STATION APPARATUS, SYNCHRONOUS CHANNEL TRANSMITTING METHOD AND TRANSMISSION METHOD - A scalable bandwidth system wherein even if a terminal does not know the breakdowns of the services in all of the bandwidths, it can perform a correlation processing of synchronous channels (SCH). A base station repetitively transmits a synchronous channel, by unit of the shortest bandwidth (e.g., 1.25 MHz) of a plurality of bandwidths served by the system, over the whole band of the longest bandwidth (e.g., 5 MHz). The terminal calculates the correlation between a synchronous channel sequence signal of the unit of the shortest bandwidth held in advance and the repetitively transmitted synchronous channel, and determines, as a frame timing, a timing at which the maximum correlation value is obtained. | 05-28-2009 |
