Method for enabling a terminal to efficiently detect and search for a femto base station

摘要

A method for enabling a mobile station (MS) to efficiently detect and search for a femto base station is disclosed. The method comprises the steps of receiving a signal including information of 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 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.

主权项

1. A method for searching for a femto base station, the method comprising:
receiving a preamble and data, wherein the preamble comprises a partial part of identification information of the femto base station and the data comprises a residual part of the identification information of the femto base station; and searching for the femto base station by identifying the femto base station based on the identification information received through the preamble and the data, wherein a sequence of the preamble (“preamble sequence”) is reused as a scrambling sequence for scrambling the data, and wherein a portion of the preamble sequence which is reused for scrambling the data is determined by comparing the length between the preamble sequence and a sequence of the data (“data sequence”).
