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.

First claim

1 . A device comprising:
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.

2 . The device according to claim 1 , wherein the control unit notifies the terminal device that the terminal device is the device candidate before the frequency band is used in the wireless communication of the cellular system.

3 . The device according to claim 1 , wherein the control unit notifies the terminal device that the terminal device is the device candidate using another frequency band for the cellular system.

4 . The device according to claim 1 , wherein the control unit notifies the terminal device that the terminal device is the device candidate in a system information block (SIB) or by individual signaling for the terminal device.

5 . The device according to claim 1 , wherein the control unit instructs the terminal device to transmit a frame including duration information for setting a network allocation vector (NAV) using the frequency band before the frequency band is used in the wireless communication of the cellular system.

6 . The device according to claim 5 , wherein the control unit uses another frequency band for the cellular system to instruct the terminal device to transmit the frame using the frequency band.

7 . The device according to claim 6 , wherein the control unit provides the terminal device with information which specifies a timing at which the frame is transmitted.

8 . The device according to claim 6 , wherein the control unit provides the terminal device with the duration information or information which specifies the duration information.

9 . The device according to claim 5 , wherein the control unit instructs the terminal device to transmit the frame using the frequency band by another frame for triggering the transmission of the frame by the terminal device.

10 . The device according to claim 1 , wherein the control unit determines whether to use the frequency band in the wireless communication of the cellular system on the basis of a result of carrier sensing for the frequency band by the terminal device.

11 . The device according to claim 1 , wherein the control unit synchronizes wireless communication using another frequency band for the cellular system with wireless communication using the frequency band.

12 . The device according to claim 1 , wherein the control unit notifies one or more terminal devices for performing wireless communication of the cellular system of a period in which the wireless communication of the cellular system is performed using the frequency band.

13 . The device according to claim 12 , wherein the control unit determines the device candidate on the basis of a result of performing measurement for the frequency band by at least some of the one or more terminal devices.

14 . The device according to claim 1 , wherein the device is a base station of the cellular system, a base station device of the base station, or a module of the base station device.

15 . A device comprising:
a recognition unit configured to recognize that a terminal device 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 through a notification by a base station of the cellular system; and a control unit configured to perform control for using the frequency band in the wireless communication of the cellular system when the terminal device is the device candidate.

16 . The device according to claim 15 , wherein the control includes controlling transmission of a frame by the terminal device so that the frame including duration information for setting a NAV is transmitted using the frequency band.

17 . The device according to claim 15 , wherein the control includes notifying the base station of a result of carrier sensing by the terminal device.

18 . The device according to claim 15 , wherein the control unit achieves synchronization for the frequency band on the basis of a result of achieving synchronization for another frequency band for the cellular system.

19 . The device according to claim 15 ,
wherein the recognition unit recognizes a period in which the wireless communication of the cellular system is performed using the frequency band through a notification by the base station, and wherein the control unit performs measurement for the frequency band in the period.

20 . The device according to claim 15 , wherein the device is the terminal device or a module of the terminal device.

21 . The device according to claim 1 ,
wherein a duplex operation of the cellular system is frequency division duplex (FDD), and wherein the frequency band is used as a downlink band in the cellular system.
