Document Type and Number:
WIPO Patent Application WO/2017/154327
Kind Code:
A1
Abstract:
A wireless communication device is configured to wirelessly transmit predetermined information possessed by the wireless communication device to a master device corresponding thereto at predetermined transmission intervals, and the wireless transmission is performed in accordance with a predetermined time division multiple access scheme. The wireless communication device: acquires, from a predetermined wireless slave device included in one or more wireless slave devices different from the wireless communication device, unrelated transmission information that is transmission information wirelessly transmitted to a master device, corresponding to the predetermined wireless slave device, in accordance with the predetermined time division multiple access scheme and that includes identification information identifying the predetermined wireless slave device, the unrelated transmission information being acquired at the time of the wireless transmission; on the basis of the identification information included in the unrelated transmission information, the acquisition time of the unrelated transmission information, and information relating to a transmission sequence, determines a predetermined time slot for the wireless communication device to transmit the predetermined information to the master device corresponding thereto in accordance with the predetermined time division multiple access scheme; and transmits the predetermined information. Consequently, provided is wireless communication technology that enables information collection using high-speed and highly reliable wireless communication.
