Abstract
An apparatus and method operable to enable the use of synchronization (SCH) and broadcast channel (BCH) signals with a bandwidth (BW) equal to the minimum possible BW for the system, for example 1.25 MHz. The present invention increases the speed of the initial cell search. In addition, the repetition of signals in the frequency domain makes it possible to perform a faster cell detection in the event a system/mobile terminal/UE is using a larger BW. When the present invention is used in a high BW system, a mobile terminal/UE is operable to determine whether to perform a cell search on a low or high BW to get sufficient cell detection performance.
