Abstract(in English) Cognitive Radio is attracting much attention for achieving high frequency spectrum usage efficiency. In cognitive radio, while the licensed user (primary user) is not using a frequency channel, the secondary user uses it, temporally. In cognitive radio, the parameters for controlling modulated signal, such as frequency, phase (time), and power, should be controlled for protecting the other user's access as well as enlarging the throughput performance of the own system. In this paper, we pay attention to MAC protocol, which is specialized for controlling the wireless parameters. We consider the task of MAC protocol for constructing cognitive radio system and the countermeasure of it. In the countermeasure, we propose the intelligent access protocol and the high speed and intelligent rendezvous channel, where the rendezvous channel is the method for synchronizing between the transmitter's frequency channels and the receiver's one. Finally, we clarify the advantages of the intelligent MAC protocol compared to the conventional one and thus show the importance of MAC protocol for constructing cognitive radio system.
