METHOD AND APPARATUS FOR DETERMINING CELL TIMING IN WIRELESS COMMUNICATION SYSTEM Russian patent published in 2011 - IPC H04J11/00 

FIELD: information technology.

SUBSTANCE: techniques for determining cell timing in a wireless communication system are described. User equipment (UE) may obtain received samples which include at least one synchronisation signal generated based on a cell identifier. The UE may correlate the received samples with the at least one synchronisation signal in the time domain at different time offsets to obtain energies for multiple timing hypotheses. The UE may identify at least one detected peak based on the energies for the multiple timing hypotheses. The UE may then update a set of candidate peaks based on the at least one detected peak and may identify a candidate peak with signal strength exceeding the signal strength of a peak being tracked. The UE may provide the timing of the identified candidate peak as the timing of the cell.

EFFECT: faster cell search.
