Method and Apparatus for Allocating Bandwidth Request Channel in Wireless Communication System Including Relay Station
First Claim
1. A method of allocating a bandwidth request channel (BRCH) in a wireless communication system including a relay station (RS), the method comprising:
- allocating at least one first BRCH for a bandwidth request of a mobile station (MS) connected to a base station (BS) and at least one second BRCH for a bandwidth request of the RS,wherein an opportunity index is assigned to each of the at least one first BRCH and the at least one second BRCH, andthe opportunity index assigned to the at least one second BRCH is started after the opportunity index assigned to the at least one first BRCH.

Abstract
A method and apparatus of allocating a bandwidth request channel (BRCH) in a wireless communication system including a relay station (RS) is provided. At least one first BRCH for a bandwidth request of a mobile station (MS) connected to a base station (BS) and at least one second BRCH for a bandwidth request of the RS are allocated. An opportunity index is assigned to each of the at least one first BRCH and the at least one second BRCH, and the opportunity index assigned to the at least one second BRCH is started after the opportunity index assigned to the at least one first BRCH.

10. A method of sending a bandwidth request signal by a relay station (RS) in a wireless communication system including the RS, the method comprising:
-
receiving an RS configuration command message from a base station (BS), and sending the bandwidth request signal to the BS through at least one RS BRCH, allocated for the bandwidth request of the RS, based on the RS configuration command message, wherein the at least one RS BRCH is allocated to a UL relay zone within a frame, used by the RS in order to send a signal to the BS, an opportunity index is allocated to the at least one RS BRCH, and the opportunity index allocated to the at least one RS BRCH is started after an opportunity index of at least one MS BRCH allocated to a UL access zone for a bandwidth request of an MS connected to the BS. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A relay station (RS) in a wireless communication system, the RS comprising:
-
a radio frequency (RF) unit configured to send or receive a radio signal; and a processor connected to the RF unit, wherein the processor is configured to; receive an RS configuration command message from a BS, and send a bandwidth request signal to the BS through at least one RS BRCH, allocated for the bandwidth request of the RS, based on the RS configuration command message, wherein the at least one RS BRCH is allocated to a UL relay zone within a frame, used by the RS in order to send a signal to the BS, an opportunity index is allocated to the at least one RS BRCH, and the opportunity index allocated to the at least one RS BRCH is started after an opportunity index of at least one MS BRCH allocated to a UL access zone for a bandwidth request of an MS connected to the BS.
