Abstract

Device to device (D2D) communication control is provided. A method comprises: allocating a pilot channel resource for at least one directional pilot signal associated with directional D2D communication; and sending information associated with the pilot channel resource. A respective pilot channel resource for a direction pilot signal can be allocated for each direction D2D communication, thereby providing a basis for better control of the D2D communication.

First claim

What is claimed is:

1. A method, comprising:
receiving, by a system comprising a processor, first information associated with a pilot channel resource for at least one directional pilot signal associated with a directional device to device (D2D) communication, wherein the directional D2D communication refers to D2D communication performing directional transmission over a D2D communication link, and wherein the directional transmission refers to transmission of a radio frequency signal in a specific direction implemented with one or more directional transmitting antennas;
sending the at least one directional pilot signal at least according to the first information;
receiving a query associated with a directional transmission capability of at least one party in both parties of a communication using a communication link of the directional D2D communication; and
sending second information associated with the directional transmission capability of the at least one party.

2. The method of claim 1 , further comprising:
sending request information associated with establishing the communication link of the directional D2D communication.

3. The method of claim 2 , wherein the request information comprises: third information associated with another directional transmission capability of at least one other party in both parties of the communication.

4. The method of claim 2 , wherein the request information comprises: third information associated with using directional transmission over the communication link.

5. The method of claim 1 , wherein the second information comprises an indication that a sender device of the at least one party will use directional transmission over the communication link.

6. The method of claim 1 , wherein the second information comprises a directional coefficient of the directional transmission.

7. The method of claim 1 , wherein the second information comprises an indication that the sender device uses beam forming over the communication link.

8. The method of claim 1 , wherein the first information comprises a pilot configuration of the at least one directional pilot signal.

9. An apparatus, comprising:
a memory that stores executable modules; and
a processor, coupled to the memory, that executes or facilitates execution of the executable modules, the executable modules comprising:
a first reception module configured to receive resource information associated with a pilot channel resource for a directional pilot signal associated with a directional device to device (D2D) communication, wherein the directional D2D communication refers to D2D communication performing directional transmission over a D2D communication link, and wherein the directional transmission refers to transmission of a radio frequency signal in a specific direction implemented with one or more directional transmitting antennas;
a first sending module configured to send the directional pilot signal at least according to the resource information;
a second reception module configured to receive a query associated with a directional transmission capability of a party of both parties to a communication using a communication link of the directional D2D communication; and
a second sending module configured to send capability information associated with the directional transmission capability of the party.

10. The apparatus of claim 9 , wherein the executable modules further comprise:
a third sending module configured to send request information associated with establishing the communication link of the directional D2D communication.

11. The apparatus of claim 10 , wherein the request information comprises: third information associated with another directional transmission capability of at least one other party in both parties of the communication.

12. The apparatus of claim 10 , wherein the request information comprises: third information associated with using directional transmission over the communication link.

13. The apparatus of claim 9 , wherein the capability information associated with the directional transmission capability comprises at least one: a first indication that a sender device of the party will use directional transmission over the communication link, a directional coefficient of the directional transmission, or a second indication that the sender device uses beam forming over the communication link.

14. A non-transitory computer readable medium, comprising at least one executable instruction, which, in response to execution, causes a system comprising a processor to perform operations, comprising:
receiving information associated with a pilot channel resource for a directional pilot signal associated with a directional device to device (D2D) communication, wherein the directional D2D communication refers to D2D communication performing directional transmission over a D2D communication link, and wherein the directional transmission refers to transmission of a radio frequency signal in a specific direction implemented with one or more directional transmitting antennas;
sending the directional pilot signal at least according to the information;
receiving a query associated with a directional transmission capability of at least one party in both parties of a communication using a communication link of the directional D2D communication; and
sending second information associated with the directional transmission capability of the at least one party.

15. The non-transitory computer readable medium of claim 14 , wherein the operations further comprise:
sending request information associated with establishing the communication link of the directional D2D communication.

16. The non-transitory computer readable medium of claim 15 , wherein the request information comprises: third information associated with another directional transmission capability of at least one other party in both parties of the communication.

17. The non-transitory computer readable medium of claim 15 , wherein the request information comprises: third information associated with using directional transmission over the communication link.

18. The non-transitory computer readable medium of claim 14 , wherein the second information comprises an indication that a sender device of the at least one party will use directional transmission over the communication link.

19. The non-transitory computer readable medium of claim 14 , wherein the second information comprises a directional coefficient of the directional transmission.

20. The non-transitory computer readable medium of claim 14 , wherein the second information comprises an indication that the sender device uses beam forming over the communication link.
