Abstract
A user equipment (UE) in a communication system measures the power received in a bandwidth on possible downlink carriers in a frequency band that is supported by the UE in order to search for available carriers. Search times can be decreased on average by using a specially configured filter to process the received power measurements and then determining likely carriers based on the filtered values. Metrics from the filter can be used to indicate both where to perform cell search and where not to perform cell search.
