Abstract

A method for performing a bandwidth request procedure in a wireless communication system includes receiving a bandwidth request sequence, which has been selected from a sequence set including a plurality of sequences, via a bandwidth request channel, and selecting a bandwidth request procedure to be performed from among a general bandwidth request procedure and a quick bandwidth request procedure, wherein the sequence set is divided into a plurality of sub-sets corresponding to the general bandwidth request procedure and the quick bandwidth request procedure. The bandwidth request procedure can be quickly and effectively performed.

Claims

1. A method for performing a bandwidth request procedure in a wireless communication system, the method comprising:

receiving a bandwidth request indicator via a pilot tone of a bandwidth request channel; and

selecting the bandwidth request procedure to be performed from among a general bandwidth request procedure and a quick bandwidth request procedure,

wherein a plurality of subset of the bandwidth request indicator are discriminated into at least one sequence for the general bandwidth request procedure and at least one sequence for the quick bandwidth request procedure,

wherein the bandwidth request procedure is selected by selecting one of the at least one sequence for the general bandwidth request procedure and the at least one sequence for the quick bandwidth request procedure after comparing an arbitrarily selected number and a threshold value for discriminating the plurality of subset of the bandwidth request indicator.

2. The method of claim 1, wherein the plurality subset of the bandwidth request indicator are discriminated according to the type of a service to be performed.

3. The method of claim 1, wherein the plurality of subset of the bandwidth request indicator are divided into at least one sequence with respect to a real time service and at least one sequence with respect to a non-real time service.

4. The method of claim 1, wherein the plurality of subset of the bandwidth request indictor are multiplexed and transmitted via the bandwidth request channel.

5. The method of claim 1, wherein a bandwidth request message including information required for a bandwidth allocation is transmitted along with the bandwidth request indicator.
