Patent number: 8594033Abstract: There is provided a technique of establishing a communication between a transmitting node and a receiving node by selecting a suitable frequency band for communication without using a predetermined control channel. Firstly, a frequency band to be used as a control channel is selected from among low frequency bands, and information on frequencies and information on application's quality requirements are exchanged between the transmitting node and the receiving node using the control channel. Then, a frequency band to be used as a data channel is determined, and a communication is started. During the communication, frequency use statuses around the transmitting node and the receiving node are notified through the control channel, and when the control channel or data channel being used becomes unusable, the channel is dynamically changed.Type: GrantFiled: December 7, 2009Date of Patent: November 26, 2013Assignees: Toyota Infotechnology Center Co., Ltd., Kyushu Institute of TechnologyInventors: Onur Altintas, Yuji Oie, Masato Tsuru, Kazuya Tsukamoto

Patent number: 8594666Abstract: Provided is a technique that enables quicker detection of usable frequency bands in a cognitive radio system. Each radio communication apparatus in the system has, in common, a hash function used to obtain a frequency range from time information and location information. Each radio communication apparatus detects unused frequency bands while narrowing down a frequency range over which a detection process is performed by obtaining the terminal's own location information and current time information from GPS signals, and input them to the hash function. Since a transmitting node and a receiving node that perform a communication are at locations close to each other at the same time, they perform detection in the same frequency range. Therefore, an unused frequency band(s) that is usable by both of them can be detected. Furthermore, at different locations or at different times, the detection will be performed in different frequency ranges. Therefore efficient frequency utilization can be achieved.Type: GrantFiled: December 7, 2009Date of Patent: November 26, 2013Assignees: Toyota Infotechnology Center Co., Ltd., Kyushu Institute of TechnologyInventors: Onur Altintas, Yuji Oie, Masato Tsuru, Kazuya Tsukamoto
