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).

Abstract: A frame communication device in a broadband wireless communication system and a method are provided to enable a base station and a relay station to communicate with a terminal by using the same resources at the same time in the broadband wireless communication system using relay, thereby increasing radio resources usable for the base station to transceive data. During the first section of a subframe, base stations and relay stations perform communication(401). During transferring to the second section of the subframe, the relay stations and terminals of the first area conduct communication(403). During the second section of the subframe, terminals of the second area within a sector different from a sector where the relay stations are located perform communication with the base stations(405,407).

Abstract: A time division scheduling apparatus and a method in a time division duplex system are provided to reduce interference between adjacent cells by scheduling and time-dividing time slots of uplink and downlink according to a channel condition. A transmission end estimates a channel for transmitting a signal to a reception end by using a signal received from the reception end(701). The transmission end determines a channel occupancy rate to transmit the signal to the reception end by using the estimated channel information(703). The transmission end determines a channel occupancy time for transmitting the signal according to the channel occupancy rate(705). The transmission end allocates a channel according to the determined channel occupancy time(707).
