Patent ID: 7796637

Claim:
A radio communication method comprising: a step in which when a first radio communication device detects a beacon of another network in a beacon transmission period used in a network to which the device belongs, the first radio communication device transmits a beacon performing a collision notification which gives notice of a collision of the detected beacon and gives notice that the beacon transmission period is moved to a new beacon transmission period excluding the detected beacon of the other network; a step in which when a second radio communication device which belongs to the same network as the first radio communication device receives the collision notification from the first radio communication device, the second radio communication device relays and transmits the collision notification; a step in which when a third radio communication device which belongs to the same network as the first radio communication device and the second radio communication device receives a collision notification from the second radio communication device, the third radio communication device also relays and transmits the collision notification; a step in which the first radio communication device transmits a beacon after moving in the new beacon transmission period; a step in which when the second radio communication device receives the beacon from the first radio communication device, the second radio communication device transmits a beacon in the new beacon transmission period; and a step in which when the third radio communication device receives the beacon from the second radio communication device, transmits a beacon in the new beacon transmission period.
