A method of generating a code sequence and method of adding additional information using the same are disclosed, by which a code sequence usable for a channel for synchronization is generated and by which a synchronization channel is established using the generated sequence. The present invention, in which the additional information is added to a cell common sequence for time synchronization and frequency synchronization, includes the steps of generating the sequence repeated in time domain as many as a specific count, masking the sequence using a code corresponding to the additional information to be added, and transmitting a signal including the masked sequence to a receiving end.

The present invention relates to a synchronization associated channel, and more particularly, to a method of generating a code sequence and method of adding additional information using the same. Although the present invention is suitable for a wide scope of applications, it is particularly suitable for generating a code sequence usable for a channel for synchronization and configuring a synchronization channel using the generated sequence.
First of all, a synchronization channel (hereinafter abbreviated SCH) as an example of a specific channel is explained as follows.
In order for a user equipment to communicate with a base station in a mobile communication system, the user equipment primarily performs synchronization with the base station on SCH and then secondarily performs a cell search. A series of process for performing synchronization with a base station and obtaining an ID of a cell to which a user equipment belongs is called a cell search.
The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention and together with the description serve to explain the principles of the invention.

FIG. 1 is a flowchart of a cell search procedure;
Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.
The present embodiment relates to synchronization channels. And, the synchronization channels can be classified into P-SCH and S-SCH. The present embodiment proposes a method of having additional information included in the synchronization channel. And, the present embodiment proposes a method of generating a sequence usable for the synchronization channel.
First of all, a method of having additional information included in a synchronization channel according to a first embodiment of the present invention is explained.
