Patent ID: 7613202

Claim:
A radio communication method, comprising: a step in which a first radio communication device sends communication time reservation request information addressed to a second radio communication device, in which a time slot when data will be transmitted to the second radio communication device is written; a step in which the second radio communication device sends communication time reservation response information, in which notice of reception of the communication time reservation request information is added to the communication time reservation request information; a step in which a third radio communication device which has received the communication time reservation request information from the first radio communication device or the communication time reservation response information from the second radio communication device or both stores the time slot written in the communication time reservation request information or the communication time reservation response information as a transmission prohibited time slot; a step in which the third radio communication device decides upon a time slot in which its own transmission and reception are possible, based on the stored transmission prohibited time slots; and a step in which when the second radio communication device counts that the transmission prohibited time slot decided based on communication time reservation request information or communication time reservation response information or both which are not addressed to the second radio communication device overlaps with a time slot in which communication addressed to the second radio communication device is reserved, more than a predetermined number of times, the second radio communication device forwards communication time reservation request information and communication time reservation response information which are not addressed to it and which are received from that time onward, to radio communication devices in the transmittable area.
