Abstract
Transmitting signals, e.g., high power narrow band signals on a periodic basis to facilitate detection of a frequency band and/or carrier signal to be used for communication with a basestation are described. The detected frequency band may be a downlink frequency band. The uplink frequency band to be used can be determined from a know frequency relationship between the detected downlink carrier and a corresponding uplink carrier or by monitoring the detected downlink frequency band for information indicating the uplink frequency band/carrier to be used. Carrier search methods involving searching for the narrowband high power signals used to provide carrier information and/or to indicate the frequency band to be monitored are described. Power detection methods can be used to detect the high power signals avoiding the need for symbol timing synchronization and/or channel estimation with regard to detection of the signals used to locate the frequency band to be used.
