Abstract
In order to provide a wireless communication system capable of improving the throughput of wireless communication by effectively using frequency resources, in a wireless communication system in which a first wireless access point which communicates with one or more wireless stations within a first cell by orthogonal frequency-division multiple access and a second wireless access point which is capable of performing carrier sensing with the first wireless access point and communicates with one or more wireless stations within a second cell by the orthogonal frequency-division multiple access operate in cooperation with each other, the first wireless access point includes a transmission opportunity acquiring unit which acquires a transmission opportunity when data to be transmitted is generated; and a transmitting unit of permission for use which transmits permission for use of channels which are not scheduled to use within the first cell, to the second wireless access point in a period in which the transmission opportunity is acquired, and the second wireless access point includes a communication unit which communicates with the wireless station within the second cell via the channe…
