Optimized signaling of primary scrambling codes and frequency lists in wireless communications
First Claim
1. A method, comprising:
- receiving cell identifier split information related to one or more cells in one of a plurality of overhead messages based at least in part on a network deployment, wherein the cell identifier split information indicates whether a list or range of the one or more cell identifiers belong to one or more closed subscriber group (CSG) cells, whether one or more frequencies are dedicated to CSG cell operation, or any combination thereof; and
utilizing, by a mobile device, the cell identifier split information to identify at least one of the one or more cells based at least in part on a broadcast signal received from the at least one of the one or more cells.

Abstract
Systems and methodologies are described that facilitate communicating PSC split information regarding neighboring cells. The PSC split information can be transmitted in one or more overhead messages selected based on network deployment. Where macro cells and femto cells provide PSC split information, which can be a PSC range for related cells, PSC list, etc., the information can be transmitted in a low priority overhead message since it can be obtained at a source cell. Where only femto cells or closed subscriber group (CSG) cells provide PSC split information, the information can be transmitted in a higher priority more frequently transmitted message. In this regard, the information is available at target cells since not all devices can access CSG cells. Thus, by providing the PSC split information in a more frequently transmitted message, devices can retrieve the PSC split information early on in communications to lower power consumption.
