Abstract
A method for providing cell selection in time division synchronous code division multiple access (TD-SCDMA) systems is provided. The method includes generating, by a user equipment (UE), an ordered list of universal absolute radio frequency channel numbers (UARFCNs) based on received signal strength indicator (RSSI) measurements associated with one or more UARFCNs, calculating synchronization downlink (SyncDL) correlation energies associated with the UARFCNS, arranging the one or more UARFCNs based on the RSSI and the associated SyncDL correlation energies, scanning the one or more UARFCNs to detect if one or more serving cells are available to be camped on and selecting a serving cell based on a signal to noise ratio (SNR) threshold associated with the UARFCN.

4. A method for providing cell selection in time division synchronous code division multiple access (TD-SCDMA) systems, the method comprising:
-
selecting a plurality of universal absolute radio frequency channel numbers (UARFCNs) from a database based on a previously camped cell information; determining a received signal strength indication (RSSI) and synchronization downlink (SyncDL) correlation energies associated with the RSSI; arranging the plurality of UARFCNs into a first list and a second list based on a location area update (LAU) information; scanning the plurality of UARFCNs to detect if one or more cells are available from the first list and the second list; and selecting a serving cell based on a signal to noise ratio (SNR) threshold associated with the serving cell. - View Dependent Claims (5, 6, 7, 8, 9, 10)
