Abstract
In a wireless communication system capable of communication with a frequency hopping method, if predetermined control information is received from a third wireless communication device while a first wireless communication device is in communication with a second wireless communication device, the first wireless communication device interrupts the communication with the second wireless communication device and executes communication with the third wireless communication device. When the communication between the first and third wireless communication devices is terminated, the communication with the second wireless communication device is re-started. All these communications are executed in a same hopping pattern, and the second wireless communication device switches the frequency according to such hopping pattern even while the communication is interrupted.
