Title:
METHOD FOR ENABLING A TERMINAL TO EFFICIENTLY DETECT AND SEARCH FOR A FEMTO BASE STATION
Document Type and Number:
WIPO Patent Application WO/2010/067968
Kind Code:
A2
Abstract:
A method for enabling a terminal to efficiently detect and search for a femto base station is disclosed. The method comprises the steps of: receiving a signal including information on a femto base station; and searching for the femto base station on the basis of the received information, wherein said received information is a sequence including at least one or more of the following: the entirety or a part of a femto base station ID (Identity); the entirety or a part of a cell ID; a sector ID; the entirety or a part of a CSG (Closed Subscriber Group) ID; and a frequency allocation index. In the step of receiving femto base station information, a preamble and data containing information on the femto base station are received. In the step of detecting the femto base station, the femto base station is separately detected on the basis of the received information. Here, the entirety or a part of the preamble sequence of the femto base station which is used for the separation of the femto base station is reused as a scrambling sequence for said data.
