WIRELESS COMMUNICATION SYSTEM, COMMUNICATION DEVICE AND PROCESSING METHOD

摘要

In the present invention, a first communication device (110) allocates, to a second communication device (120), a first candidate and a second candidate for a use resource in a prescribed band shared with another wireless communication system. The second communication device (120) detects the availability of a wireless resource on the basis of the results of allocating the first candidate and the second candidate by the first communication device (110). The second communication device (120) sends a wireless signal to the first communication device (110) using the first candidate if the first candidate is available. In addition, the second communication device (120) sends a wireless signal to the first communication device (110) using the second candidate if the first candidate is not available and the second candidate is available.
