Abstract
Techniques are described for wireless communication. One method includes searching for a synchronization channel on a first raster point of a frequency raster identified for synchronization channel transmission. The frequency raster includes a plurality of raster points in a radio frequency spectrum. The method also includes identifying a pull-in signal on the first raster point; determining, from the pull-in signal, a second raster point of the frequency raster on which the synchronization channel is transmitted; and receiving the synchronization channel on the second raster point. Another method includes transmitting the pull-in signal and the synchronization channel.
