Abstract
A wireless communication device that transmits packets, on the basis of a packet transmission scheme for allocating wireless bands with virtual carrier sensing, has: monitoring module for monitoring packets communicated between other wireless communication devices and base stations for a local cell and another cell; determination module for determining whether a possibility exists that a local station receives other-cell interference resulting from communication between the wireless communication device in the other cell and the base station, on the basis of the monitoring result; occupancy period detection module for detecting an occupancy period occupied due to communication between the wireless communication device in the other cell and the base station, on the basis of the monitoring results, when determination is made that receiving the other-cell interference is possible; and timing recognition module for recognizing a timing for avoiding the other-cell interference in a predetermined period on the basis of the occupancy period.
