Claim Text:
1. A central control unit for providing contention based channel access in a wideband wireless communication system, the central control unit comprising: a source allocation scheduling unit to allocate a resource by dividing the contention period into a sector sweepable contention period corresponding to a contention period during which a sector sweeping operation by a dispersion device in communication with the central control unit is performed and a non-sector sweepable contention period corresponding to a contention period during which the sector sweeping operation is not performed; and a beacon generator to generate a beacon message including information about the sector sweepable contention period and the non-sector sweepable contention period, and to transmit the beacon message to the dispersion device, wherein the dispersion device manages, for each of predetermined directions, information of a transmission duration corresponding to a network allocation vector included in a message that is wirelessly received in a state set to an omnidirectional receiving antenna mode, and the dispersion device starts communication in a first direction among the predetermined directions when the information of the transmission duration of the first direction is a predetermined value.
