Resource Request and Allocation Method of Using Bandwidth Request Ranging and Appartus Therefor

The present invention relates to a resource request method, the allocation method and an apparatus therefor using the bandwidth request ranging in the mobile communication system. To this end, the invention provides a method for allocating uplink resources to the subscriber station using a bandwidth request ranging in a mobile communication system, the code group information, - wherein the code group information divides the bandwidth request code into a plurality of groups each sending an uplink channel identifier included in the subscriber terminal-one mapped to the data block size is set to the group in advance information Im; Receiving a selected bandwidth request code in the subscriber terminal; Identifying a code group including the selected bandwidth request code; And the bandwidth to send the data block size corresponding to the check code group comprises the step of assigning to a subscriber terminal. According to the present invention, a bandwidth request code in the divided each group, the bandwidth request code for each group according to the uplink traffic by the receiving it so as to represent a particular block size BS to allocate an uplink resource by which a bandwidth request code means this has the effect of reducing the transmission delay. Mobile Internet, the bandwidth request ranging, the uplink traffic
