WIRELESS NETWORK SYSTEM AND METHOD OF CONTROLLING THE SAME

摘要

PROBLEM TO BE SOLVED: To facilitate establishing timing synchronization and enable radio communication at a radio station of a secondary system, in a wireless network system including two radio communication systems.

SOLUTION: In the wireless network system having a first radio communication system performing data transmission after exchanging control signals and a second radio communication system performing data transmission by using and superposing the same frequency band as that of the first radio communication system, a transmitting-side radio station of the second radio communication system predicts a timing of data transmission of the first radio communication system based on the control signal of the first radio communication system and transmits data to be transmitted at the predicted timing, and a receiving-side radio station of the second radio communication system predicts a timing of data transmission of the first radio communication system based on the control signal of the first radio communication system and receives data from the transmitting-side radio station of the second radio communication system at the predicted timing.
