1. A method for generating a Synchronization CHannel (SCH) in an upper node in a wireless communication system, the method comprising:
- checking, by the upper node, a sequence of a first SCH being an SCH for a mobile station (MS) and a mask sequence; and
generating a sequence of a second SCH being an SCH for a relay station (RS) by XOR-operating the first SCH sequence and the mask sequence.

Abstract
An apparatus and method for generating an RS SCH in a wireless communication system are provided, in which a base station checks a BS SCH sequence and a mask sequence, and generates an RS SCH sequence by XOR-operating the BS SCH sequence and the mask sequence.

18. A method for acquiring a Synchronization CHannel (SCH) in a relay station (RS) in a wireless communication system, the method comprising:
-
checking, by the relay station. a sequence of a first SCH being an SCH for a mobile station (MS) received from an upper node and a mask sequence; generating a sequence of a second SCH being an SCH for a relay station by XOR-operating the first SCH sequence and the mask sequence; and acquiring, upon receipt of a second SCH from the upper node, synchronization to the upper node by correlating the generated second SCH with the received second SCH. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
