ABSTRACT:
A method of requesting resources, a method of allocating resources, and an apparatus therefor by using bandwidth request ranging in a mobile communication system are provided. The method of allocating uplink resources to a subscriber station by using bandwidth request ranging in a mobile communication system includes: transmitting an uplink channel descriptor (UCD) including code group information to the subscriber station, wherein the code group information is obtained by dividing a bandwidth request code into a plurality of groups and mapping the groups to predetermined data block sizes; receiving a bandwidth request code selected in the subscriber station; determining a code group including the selected bandwidth request code; and allocating a bandwidth through which a data block size corresponding to the determined code group can be transmitted, to the subscriber station. Accordingly, bandwidth request codes are divided into code groups of which bandwidth request codes represent specific block sizes, and the base station that receives the bandwidth request code allocates uplink resources corresponding to the bandwidth request code, so that it is possible to decrease a transmission delay of the uplink traffic.
