Patent Searching and Data


Title:
METHOD AND APPARATUS FOR CELL SEARCH IN ORTHOGONAL WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
Japanese Patent JP2012165401
Kind Code:
A
Abstract:

To provide systems and methodologies that provide techniques for efficient cell search in a wireless communication system.

A frequency reuse pattern 510 is generated by applying frequency shifts to reference signals transmitted from cells that provide coverage for a Node B based on cell IDs or cell group IDs for the cells. The frequency shifts applied to the reference signals can then be utilized as a basis for multiplexing the reference signals from different cells using frequency division multiplexing (FDM) or a combination of FDM and other multiplexing techniques. Other adjustments to the reference signals transmitted from respective cells, such as transmit power adjustments, can further be made to improve detection performance.
