COGNITIVE RADIO COMMUNICATION DEVICE, COGNITIVE RADIO TERMIANL DEVICE AND METHOD FOR COGNITIVE RADIO COMMUNICATION

摘要

PURPOSE: A cognitive radio communication device, cognitive radio terminal device, and a method for cognitive radio communication are provided to efficiently use radio frequency resources by transmitting data through one radio channel for more than two users. CONSTITUTION: A cognitive radio communication(310) comprises a receiver(311), a signal generator(312), and a transmission unit(313). The receiver receives a first transmission signal about the priority user data. The priority user data is transmitted from a communication device of the priority user. A signal generator creates the second transmission signal by the first transmission signal which is received as described above and the next user data. The transmission unit transmits the second transmission signal through the radio channel.
