A carrier sense multiple access method capable of improving throughput in a wireless network is disclosed. This method is implemented in a wireless network-for example, a wireless LAN ( 100 )-having an AP ( 110 ) that is equipped with a multi-beam antenna ( 111 ) that forms a directional beam and that is capable of SDMA, and a STA ( 120, 130, 140 ) that communicate with the AP ( 110 ). With this method, the AP ( 110 ) allots the STA ( 120 to 140 ) to a beam group defined by a coverage area of the directional beam, according to the location of the STA ( 120 to 140 ). Then, the allocated STA ( 120 to 140 ) is assigned a signature signal for group identification, the signature signal being unique to the group.
