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 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.

2. The method of claim 1, wherein the plurality of sub-sets are discriminated according to the type of a service to be performed.

3. The method of claim 1, wherein the plurality of sub-sets comprise a sub-set with respect to a real time service and a sub-set with respect to a non-real time service.

4. The method of claim 1, wherein the bandwidth request sequence is selected from any one of the sub-set with respect to the general bandwidth request procedure and the sub-set with respect to the quick bandwidth request procedure after comparing an arbitrarily selected number and a threshold value for discriminating the plurality of sub-sets.

5. The method of claim 1, wherein a plurality of bandwidth request sequences are multiplexed and transmitted via the bandwidth request channel.

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

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

transmitting a sequence selected from any one of a sequence set for performing a first bandwidth request procedure and a sequence set for performing a second bandwidth request procedure;

receiving an uplink grant message including allocation information of uplink radio resource in response to the sequence; and

transmitting data through the uplink radio resource.

8. The method of claim 7, wherein the first bandwidth request procedure is performed with a smaller number of steps than that of the second bandwidth request procedure.

9. The method of claim 7, wherein the data is a bandwidth request message including information required for a bandwidth allocation.

10. The method of claim 7, wherein the data is user data.
