Fast cell search
First Claim
1. A method that facilitates a multi-stage cell search, comprising:
- detecting timing information related to primary synchronization channels (PSCs);
determining cyclic prefix (CP) length based on a relative time distance between two consecutive PSCs; and
identifying a cell based in part on phase information associated with a secondary synchronization channel (SSC).

Abstract
Systems and methodologies are described that facilitate searches for a cell in a wireless communication environment. A mobile device can employ a searcher that can detect timing information respectively associated with PSCs and cells to determine the cell with the highest correlation. The searcher can detect SSCs, which can include detecting associated phase information, to determine the SSC with the highest correlation, CP length, and/or other information to facilitate identifying a desired cell having the strongest signal to establish communication between the mobile device and the desired cell. PSCs respectively associated with cells can have different positions in the symbol sequences, and SSCs can respectively be phase shifted at different angles to facilitate detection and identification of a cell(s), where a PSC can be utilized as a phase reference by the associated SSC.
