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:

circuitry including at least a processor and a memory, the circuitry configured to;

determine a proxy paging reception timing of one or more other terminal devices based at least in part on identification information of the one or more other terminal devices belonging to a network of the terminal device;

cause a base station to update a transmission timing of a paging message based on the determined proxy paging reception timing;

acquire the paging message from the base station that executes a paging operation according to the updated transmission timing of the paging message; and

execute paging with respect to the one or more other terminal devices based on the acquired paging message; and

separate paging frames of the proxy paging reception timing for the one or more other terminal devices by an offset amount from a paging frame of the terminal device, wherein the offset amount is determined using the identification information of the one or more other terminal devices.

2. The terminal device according to claim 1, wherein the circuitry is further configured to prescribe a timing of paging with respect to the one or more other terminal devices independently of another timing of paging from the base station.

3. The terminal device according to claim 2, wherein the circuitry is further configured to prescribe that paging is executed in a paging frame identical to all of the one or more other terminal devices.

4. The terminal device according to claim 2, wherein the circuitry is further configured to prescribe that paging is executed in a paging frame and a subframe identical to all of the one or more other terminal devices.

5. The terminal device according to claim 2, wherein the circuitry is further configured to prescribe that paging is executed in different paging frames with respect to each of the one or more other terminal devices.

6. The terminal device according to claim 2, wherein the circuitry is further configured to prescribe that an interval of paging with respect to the one or more other terminal devices be longer than another interval of paging from the base station.

7. The terminal device according to claim 1, wherein the circuitry is further configured to transmit first information for identifying the terminal device and second information for identifying the one or more other terminal devices to the base station.

13. The terminal device according to claim 1, wherein the circuitry is further configured to separate paging occasions of the proxy paging reception timing for the one or more terminal devices using the identification information of the one or more terminal devices.

14. The terminal device according to claim 1, wherein the identification information is transmitted to the terminal device by the one or more other terminal devices before determining the proxy paging reception timing.

15. The terminal device according to claim 1, wherein the offset amount is further determined using a pool of paging frames allocated to the one or more other terminal devices.

8. A system for wireless communication, the system comprising:

a first terminal device configured to;

determine a proxy paging reception timing of one or more second terminal devices based on identification information of the one or more second terminal devices belonging to a network of the first terminal device,

cause a base station to update a transmission timing of a paging message based on the proxy paging reception timing determined,

acquire the paging message from the base station that executes a paging operation according to the updated transmission timing of the paging message, and

execute paging with respect to the one or more second terminal devices that perform the wireless communication with the base station via the first terminal device based on the paging message acquired;

separate paging frames of the proxy paging reception timing for the one or more second terminal devices by an offset amount from a paging frame of the first terminal device, wherein the offset amount is determined using the identification information of the one or more second terminal devices;

the one or more second terminal devices configured to send the identification information to the first terminal device; and

the base station configured to execute the paging operation with respect to the first terminal device and the one or more second terminal devices.

9. The system according to claim 8, wherein the first terminal device is further configured to execute paging with respect to one of the one or more second terminal devices at a timing prescribed by the first terminal device.

10. The system according to claim 8, wherein the first terminal device is further configured to prescribe a timing of paging with respect to one of the one or more second terminal devices based on information acquired from the base station.

11. A wireless communication method comprising:

determining a proxy paging reception timing of one or more second terminal devices based at least in part on identification information of the one or more second terminal devices belonging to a network of a first terminal device;

causing a base station to update a transmission timing of a paging message based on the determined proxy paging reception timing;

acquiring the paging message from the base station that executes a paging operation according to the updated transmission timing of the paging message; and

executing paging with respect to the one or more second terminal devices based on the acquired paging message;

separating paging frames of the proxy paging reception timing for the one or more second terminal devices by an offset amount from a paging frame of the first terminal device, wherein the offset amount is determined using the identification information of the one or more second terminal devices.

12. A wireless communication method comprising:

determining, by a first terminal device, a proxy paging reception timing of one or more second terminal devices based at least in part on identification information of the one or more second terminal devices belonging to a network of the first terminal device;

causing, by the first terminal device, a base station to update a transmission timing of a paging message based on the determined proxy paging reception timing;

acquiring, by the first terminal device, the paging message from the base station that executes a paging operation according to the updated transmission timing of the paging message;

executing, by the first terminal device, paging with respect to the one or more second terminal devices based on the acquired paging message;

sending, by the one or more second terminal devices, the identification information to the first terminal device;

executing, by the base station, the paging operation with respect to the first terminal device and the one or more second terminal devices; and

separating paging frames of the proxy paging reception timing for the one or more terminal devices by an offset amount from a paging frame of the first terminal device, wherein the offset amount is determined using the identification information of the one or more second terminal devices.
