1. A method for transmitting a signal for cell searching in a mobile communication system having a multi-cell environment, the method comprising:
- 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,wherein 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,wherein a combination of the first index and the second index permits identification of an identity of the cell, wherein the first index includes a cell group identifier for identifying a cell group including the cell, and wherein the second index includes a cell identifier for identifying the cell included in the cell group identified by the cell group identifier, and wherein the first index is different from the second index, andwherein the length of the first code sequence and the length of the second code sequence are identical.

Abstract
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.

3. A method for receiving a signal for cell searching in a mobile communication system having a multi-cell environment, the method comprising:
-
receiving the signal from a transmitting party device; performing a synchronization based on the received signal, wherein 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, wherein a combination of the first index and the second index permits identification of an identity of the cell, and wherein the first index is different from the second index; and finding the identity of the cell using the combination of the first index and the second index, wherein the finding comprises; obtaining a cell group identifier for identifying a cell group including at least one cell from the first index; obtaining a cell identifier for identifying the cell included in the cell group identified by the cell group identifier using the second index; and identifying the cell included within the cell group using the cell identifier, and wherein the length of the first code sequence and the length of the second code sequence are identical. - View Dependent Claims (4)
