Abstract:
1. A wireless communication device for transmitting packets, on the basis of a packet transmission scheme for allocating wireless bands with virtual carrier sensing, comprising: a monitoring module configured to monitor packets communicated between other wireless communication devices and wireless base stations, for both a local cell in which a local wireless communication device is located and another cell; a determination module configured to determine whether a possibility exists that the local wireless communication device receives other-cell interference resulting from communication between the wireless communication device in the other cell and the wireless base station which administers the other cell, on the basis of a monitoring result by the monitoring module; an occupancy period detection module configured to detect an occupancy period occupied due to communication between the wireless communication device in the other cell and the wireless base station, on the basis of the monitoring result, when the determination module determines that a possibility exists that the local wireless communication device receives the other-cell interference; and a timing recognition module configured to recognize a timing for avoiding the other-cell interference in a predetermined period on the basis of the occupancy period detected by the occupancy period detection module, wherein the determination module is configured to determine the possibility of the local wireless communication device receiving the other-cell interference when neither a transmission source address nor a destination address of a packet obtained from monitoring performed by the monitoring module matches the address of a wireless base station which administers the local cell.
