Abstract

[Object] To provide a wireless communication device which enables paging to be effectively performed with respect to a terminal device that is a target of paging in a system in which another terminal device acts like a cell.

[Solution] Provided is a terminal device including: an acquisition unit configured to acquire a paging message from a base station; and a control unit configured to execute paging with respect to one or more other terminal devices that perform wireless communication with the base station via the terminal device on the basis of the paging message acquired by the acquisition unit.

Claims

1. A terminal device comprising:

an acquisition unit configured to acquire a paging message from a base station; and

a control unit configured to execute paging with respect to one or more other terminal devices that perform wireless communication with the base station via the terminal device on the basis of the paging message acquired by the acquisition unit.

2. The terminal device according to claim 1, wherein the acquisition unit acquires a paging message that includes the paging message destined for the other terminal devices.

3. The terminal device according to claim 1, wherein the control unit prescribes a timing of paging with respect to the other terminal devices independently of a timing of paging from the base station.

4. The terminal device according to claim 3, wherein the control unit prescribes that paging is executed in a paging frame identical to all of the other terminal devices.

5. The terminal device according to claim 3, wherein the control unit prescribes that paging is executed in a paging frame and a subframe identical to all of the other terminal devices.

6. The terminal device according to claim 3, wherein the control unit prescribes that paging is executed in different paging frames with respect to each of the other terminal devices.

7. The terminal device according to claim 3, wherein the control unit prescribes that an interval of paging with respect to the other terminal devices be longer than an interval of paging from the base station.

8. The terminal device according to claim 1, wherein the control unit transmits information for identifying the terminal device and information for identifying the other terminal devices to the base station.

9. A wireless communication device comprising:

a control unit configured to execute paging with respect to a first terminal device and a second terminal device that performs wireless communication via the first terminal device; and

an acquisition unit configured to acquire information for prescribing a timing of paging by the control unit with respect to the second terminal device independently of a timing of paging with respect to the first terminal device.

10. The wireless communication device according to claim 9, wherein the control unit executes paging with respect to the second terminal device at a timing prescribed by the first terminal device.

11. The wireless communication device according to claim 9, wherein the control unit prescribes a timing of paging with respect to the second terminal device on the basis of information acquired by the acquisition unit.

12. A wireless communication method comprising:

acquiring a paging message from a base station; and

executing paging with respect to another terminal device that performs wireless communication with the base station via a terminal device on the basis of the acquired paging message.

13. A wireless communication method comprising:

executing paging with respect to a first terminal device and a second terminal device that performs wireless communication via the first terminal device; and

acquiring information for prescribing a timing of paging with respect to the second terminal device independently of a timing of paging with respect to the first terminal device.
