5. The method of claim 3, further comprising:

receiving a DTP information request requesting transmission of the DTP information from the second apparatus for each of the plurality of links, if the DTP reception setup information is set such that the DTP information is to be received for each of the plurality of links;

generating the DTP information for each of the plurality of links; and

transmitting the generated DTP information for each of the plurality of links to the second apparatus.

6. The method of claim 5, wherein the DTP information further comprises at least one of first information about a first time when DTP information is transmitted, second information about a second time when the DTP information is generated, and third information about a third time when the DTP information request is received.

7. The method of claim 1, wherein the control packet further comprises beam forming information indicating whether to perform beam forming for each of the plurality of links.

8. The method of claim 1, wherein the control packet further comprises link quality report information indicating whether to receive information about link quality for each of the plurality of links from the second apparatus.

17. A computer readable recording medium having embodied thereon a program for executing the method of claim 1.

9. A control packet generating apparatus which supports dynamic tone pairing (DTP) and is connectable to other apparatuses via a plurality of medium access control (MAC) layers, the apparatus comprising:

an information generating unit which generates dynamic tone pairing (DTP) reception setup information indicating whether to receive DTP information for each of a plurality of links from the other apparatus; and

a packet generating unit which generates a control packet including DTP setup information.

10. The control packet generating apparatus of claim 9, further comprising a reception unit which receives DTP information from the other apparatus,

wherein when the DTP reception setup information is set such that the DTP information is to be received for each of the plurality of links, the DTP information generated for each of the plurality of links is received while the reception unit receives the DTP information from the other apparatus.

11. The control packet generating apparatus of claim 9, further comprising a transmitting unit which transmits the generated control packet to the other apparatus.

12. The control packet generating apparatus of claim 10, further comprising:

a transmitting unit which transmits a DTP information request for requesting transmission of the DTP information to the other apparatus for each of the plurality of links, when the DTP reception setup information is set such that the DTP information is to be received for each of the plurality of links; and

a receiving unit which receives the DTP information from the other apparatus for each of the plurality of links.

13. The control packet generating apparatus of claim 10, further comprising:

a receiving unit which receives a DTP information request for requesting transmission of the DTP information from the other apparatus for each of the plurality of links, when the DTP reception setup information is set such that the DTP information is to be received for each of the plurality of links; and

a transmitting unit which transmits the generated DTP information for each of the plurality of links to the other apparatus, when the information generating unit generates the DTP information for each of the plurality of links.

14. The control packet generating apparatus of claim 13, wherein the DTP information further comprises at least one of first information about a first time when the DTP information is transmitted, second information about a second time when the DTP information is generated, and third information about a third time when the DTP information request is received.

15. The control packet generating apparatus of claim 9, wherein the control packet further comprises beam forming information indicating whether to perform beam forming for each of the plurality of links.

16. The control packet generating apparatus of claim 9, wherein the control packet further comprises link quality report information indicating whether to receive information about link quality for each of the plurality of links from the other apparatus.

18. A method of receiving dynamic tone pairing (DTP) information by using a first device which supports DTP and including a plurality of medium access control (MAC) layers from a second device, the method comprising:

receiving the DTP information regarding one of the plurality of MAC layers from the second device;

checking DTP reception setup indicating whether to receive DTP information for each of the plurality of links; and

selectively receiving the DTP information regarding MAC layers other than the one of the plurality of MAC layers, based on a result of the checking of the DTP reception setup.

19. The method of claim 18, wherein the receiving the DTP information regarding one of the plurality of MAC layers from the second device comprises:

transmitting to the second device a DTP information request for requesting transmission of the DTP information; and

receiving the DTP information corresponding to the DTP information request from the second device.

20. The method of claim 18, wherein the selective receiving of the DTP information regarding MAC layers other than the one of the plurality of MAC layers comprises:

if the DTP reception setup is set such that the DTP information is to be received for each of a plurality of links, the MAC layers other than the one of the plurality of MAC layers receive the DTP information generated for each of the plurality of links, and

if the DTP reception setup is set such that one piece of DTP information is to be received for all MAC layers, the MAC layers other than the one of the plurality of MAC layers do not receive the DTP information.
