Abstract
A serving cell configures a search window within which a UE searches to find a discovery burst. The discovery burst may include PSS, SSS, DS, CSI-RS or other signals. The UE detects synchronization signals and determines if the synchronization signals are part of the discovery burst by detecting signal properties to distinguish them from legacy or other synchronization signals. One property is the time difference between a PSS and an SSS in a discovery burst. Other properties are the frequency difference between a PSS and an SSS, and the sequence of the synchronization signals. If the UE determines that the synchronization signals are part of the discovery burst, the UE performs RRM measurements on other signals in the discovery burst, and reports the measurements results to a serving cell. The serving cell decides if a UE should be handed over to the measured cell based on the measurement reports.
