Device for performing wireless communication
First Claim
1. A device comprising:
- circuitry including at least a processor and a memory, the circuitry configured to;
acquire information indicating a terminal device which is a device candidate for performing a wireless communication of a cellular system using a frequency band shared between the wireless communication of the cellular system and another wireless communication conforming to a wireless local area network (LAN) standard;
notify the terminal device that the terminal device is the device candidate, wherein the terminal device performs a carrier sensing for the frequency band and report a result of the carrier sensing to the device;
determine whether or not to use the frequency band based on the result from the terminal device; and
execute a carrier sensing for the frequency band and transmit a request-to-send (RTS) frame to the terminal device when a period, in which no signal is transmitted using the frequency band, becomes inter-frame space and a back-off time.

Abstract
[Object] To enable a frequency band shared between wireless communication of a cellular system and wireless communication conforming to a wireless LAN standard to be more appropriately used in the cellular system.
[Solution] There is provided a device including an acquisition unit configured to acquire information indicating a terminal device which is a device candidate for performing wireless communication of a cellular system using a frequency band shared between the wireless communication of the cellular system and wireless communication conforming to a wireless local area network (LAN) standard, and a control unit configured to notify the terminal device that the terminal device is the device candidate.

15. A device comprising:
-
circuitry including at least a processor and a memory, the circuitry configured to; recognize that a terminal device is a device candidate for performing a wireless communication of a cellular system using a frequency band shared between the wireless communication of the cellular system and another wireless communication conforming to a wireless local area network (LAN) standard through a notification by a base station of the cellular system; and control for using the frequency band in the wireless communication of the cellular system when the terminal device is the device candidate, wherein the terminal device performs a carrier sensing for the frequency band and report a result of the carrier sensing to the base station, the base station determines whether or not to use the frequency band based on the result from the terminal device and executes a carrier sensing for the frequency band and transmit a request-to-send (RTS) frame to the terminal device when a period, in which no signal is transmitted using the frequency band, becomes inter-frame space and a back-off time. - View Dependent Claims (16, 17, 18, 19, 20)

22. A terminal device comprising:
-
circuitry including at least a processor and a memory, the circuitry configured to; receive information that the terminal device is a device candidate for performing a wireless communication of a cellular system using a frequency band shared between the wireless communication of the cellular system and another wireless communication conforming to a wireless local area network (LAN) standard through a notification by a base station of the cellular system; receive duration information which specifies a period in which a wireless communication of the cellular system is performed using the frequency band through the notification by the base station; perform a carrier sensing for the frequency band in at least a part of the period; and report a result of the carrier sensing to the base station, wherein the frequency band is used for a secondary component carrier, and another frequency band for a cellular communication is used as a primary component carrier, for the wireless communication of the cellular system. - View Dependent Claims (23, 24, 25, 26)
