Abstract
Provided is a device that acquires a result of discovery of a wireless local area network (LAN) access point that uses a frequency band, and controls monitoring of a radar wave in the frequency band based on the result of the discovery before use of the frequency band by a base station of a cellular system starts. This makes it possible to expedite the use of a frequency band used in a wireless local area network (LAN) in a cellular system.

18. A method comprising:
-
acquiring a result of discovery of a wireless LAN access point that uses a frequency band; determining whether the wireless LAN access point that uses the frequency band is discovered; in response to determining that the wireless LAN access point that uses the frequency band is not discovered, controlling, by a processor, monitoring of a radar wave in the frequency band before use of the frequency band by a base station of a cellular system starts, the use of the frequency band by the base station being use of the frequency band as a secondary component carrier of carrier aggregation; and in response to determining that the wireless LAN access point that uses the frequency band is discovered, controlling, by the processor, the monitoring in a manner that the monitoring is not performed before use of the frequency band by the base station starts.
