Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

What is claimed is: 1. A method in a communication system of identifying a carrier signal having a first bandwidth of a radio access technology based on signal measurements in a second bandwidth unrelated to the radio access technology, comprising: measuring a received energy of the carrier signal in the second bandwidth at a plurality of different frequencies in a frequency band, using a received signal strength indication (RSSI) scan, wherein the second bandwidth is different fr…
