Abstract: PURPOSE: A scheduling apparatus at an orthogonal frequency division multiple access system and a scheduling method thereof are provided to allocate a user of maximum channel quality to a subchannel block having a maximum channel quality difference by comparing channel quality differences at different subchannel blocks. CONSTITUTION: The whole numbers of subchannel blocks are set to be the same as that of users(S200). The selection reference value of the subchannel blocks is calculated(S202). An allocation subchannel block and the user are selected(S204). A process for determining whether allocation is performed or not is operated(S206,S210,S212). An allocation process is operated(S208,S214). An allocable subchannel block, subchannel block combination which is pre-allocated, and subchannel block combination which is not allocated according to a user are updated by reflecting a current allocation result(S216). An update procedure includes an allocable subchannel block range update process according to the user, an allocable subchannel block user updating process, and a verification process of unallocated subchannel block.

Abstract: A subchannel allocation apparatus and a method thereof for reducing the collision selecting an identical subchannel between users when assigning the subchannel in an orthogonal frequency division multiple access system are provided to allocate the resource of the subchannel according to the channel characteristics of the user. A base station confirms whether a user requests the allocation of the channel resource(300). If there is a user assigning the channel resource, the base station selects the user of the highest priority(302). The base station selects optimum subchannel of users(304). The base station confirms whether the contention occurs(306). The channel resource is allocated to the selected user(308).
