Abstract
Official abstract text for this publication.
A method for transmitting a signal for cell searching in a mobile communication system having a multi-cell environment includes transmitting the signal to one or more receiving party devices within a cell, wherein the signal is used for a synchronization of the one or more receiving party devices within the cell, the signal is defined by a combination of a first code sequence derived from a first index and a second code sequence derived from a second index, and an identity of the cell is used for defining the combination of the first code sequence and the second code sequence.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of transmitting a synchronization signal, the method comprising: generating a first code sequence from a first number which is related to a cell group identifier for identifying a cell group including the cell and a second code sequence from a second number which is related to a cell identifier for identifying the cell included in the cell group identified by the cell group identifier, wherein a combination of the first number and the second number indicates an identity of the cell; and transmitting the first code sequence via a first orthogonal frequency-division multiplexing (OFDM) symbol and the second code sequence via a second OFDM symbol. 2. The method of claim 1 , wherein the first OFDM symbol is ‘n’ OFDM symbol ahead from the second OFDM symbol. 3. The method of claim 2 , wherein the ‘n’ is 1.
