Abstract

An electronic device configured to perform wireless communication in accordance with vehicle-to-X (V2X) communication, the V2X communication including at least vehicle-to-vehicle (V2V) communication, vehicle-to-infrastructure (V2I) communication, and vehicle-to-pedestrian (V2P) communication, each of the V2V, V2I and V2P communications having an intermittent communication function; receive a signal associated with a location of the electronic device; determine whether to activate or deactivate a communication parameter corresponding to the V2P communication based on the signal associated with the location of the electronic device; activate or deactivate the communication parameter corresponding to the V2P communication based on the determining; and activate the intermittent communication function for the V2P communication in a case that that the parameter corresponding to the V2P communication is activated.

Claims

1. An electronic device comprising:

circuitry configured to

communicate with a movable object, a road side unit (RSU) or a base station; and

activate or deactivate a communication function of the electronic device based on information acquired depending on position,

wherein the information acquired depending on position is information indicating a relative relationship with the movable object or the RSU, and

the circuitry is further configured to acquire parameters for estimating the relative relationship based on a measurement result of a radio signal received from the movable object or the RSU.

2. The electronic device according to claim 1, wherein the relative relationship is estimated based on power of a predetermined resource pool of communication signals.

3. The electronic device according to claim 2, wherein the relative relationship is estimated in stages.

4. The electronic device according to claim 1, wherein the parameters for estimating the relative relationship include measurement gap information.

5. The electronic device according to claim 4, wherein the circuitry is further configured to change the parameters for estimating the relative relationship depending on information of the electronic device.

6. The electronic device according to claim 1, wherein the information acquired depending on position is location information of the electronic device.

7. The electronic device according to claim 6, wherein the circuitry is further configured to acquire parameters regarding the communication function to be activated.

8. The electronic device according to claim 6, wherein the circuitry is further configured to acquire synchronization using a global navigation satellite system (GNSS) signal for the communication function to be activated.

9. The electronic device according to claim 1, wherein the circuitry is further configured to notify the RSU or the base station that the communication function has been activated.

10. The electronic device according to claim 9, wherein the communication function includes a function of directly or indirectly communicating with the movable object.

11. The electronic device according to claim 10, wherein the information acquired depending on position includes information about getting in/out of a movable object transporting the electronic device.

12. The electronic device according to claim 11, wherein the information about the movable object transporting the electronic device is acquired by a procedure of attaching to or detaching from a cell provided by the movable object.

13. The electronic device according to claim 12, wherein the information about the movable object transporting the electronic device includes information about short-range wireless communication with the movable object.

14. The electronic device according to claim 1, wherein the communication function includes a function of directly or indirectly communicating with the movable object.

17. The electronic device according to claim 1, wherein the received radio signal is a discovery signal.

18. The electronic device according to claim 1, wherein the received radio signal is transmitted by another device.

15. A method comprising:

performing communication with a movable object, an RSU or a base station; and

activating or deactivating a communication function by a processor based on information acquired depending on position,

wherein the information acquired depending on position is information indicating a relative relationship with the movable object or the RSU, and

the method further comprises acquiring parameters for estimating the relative relationship based on a measurement result of a radio signal received from the movable object or the RSU.

16. An electronic device comprising:

circuitry configured to

communicate with a movable object, a road side unit (RSU) or a base station; and

activate or deactivate a communication function of the electronic device based on information acquired depending on position,

wherein the information acquired depending on position is information indicating a relative relationship with the movable object or the RSU, and

the circuitry is further configured to acquire parameters for estimating the relative relationship, wherein the information indicating the relative relationship is information indicating whether received power of a signal transmitted from the movable object or the RSU exceeds a threshold value.
