Abstract
A data receiving apparatus includes a receiving unit configured to receive a beacon packet from at least one base station, a searching unit configured to search an index of a subchannel including an optimal channel state among subchannels allocated to a sector divided through spatial multiplexing based on the base station using the beacon packet, a calculating unit configured to calculate a final back off time by adding a slot time of the subchannel index and a random time, and a transmitting unit configured to include the searched subchannel index in a beacon response packet and transmit the beacon response packet after the calculated final back off time.
