Abstract

A method and apparatus for wireless communication in a wireless personal area network (WPAN) communication system. A wireless communication method to be performed by a first wireless communication device includes broadcasting a beacon, receiving an association request signal from a second wireless communication device receiving the beacon, and performing association with the second wireless communication device after receiving the association request signal, in which the first wireless communication device may suspend beacon transmission after the association with the second wireless communication device is established.

Claims

1. A wireless communication method to be performed by a first wireless communication device, the method comprising:

broadcasting a beacon;

receiving an association request signal from a second wireless communication device receiving the beacon; and

performing association with the second wireless communication device after receiving the association request signal,

wherein the first wireless communication device is configured to suspend beacon transmission after the association with the second wireless communication device is established.

2. The method of claim 1, wherein the first wireless communication device is configured to suspend the beacon transmission until the association with the second wireless communication device is cancelled.

3. A wireless communication method to be performed by a first wireless communication device, the method comprising:

broadcasting a beacon;

receiving an association request signal from a second wireless communication device receiving the beacon; and

performing association with the second wireless communication device after receiving the association request signal,

wherein, after the association with the second wireless communication device is established, the first wireless communication device is configured to transmit a beacon in which a superframe duration (SD) is set to be infinite.

4. The method of claim 3, wherein, after transmitting the beacon in which the SD is set to be infinite, the first wireless communication device is configured to suspend beacon transmission until the association with the second wireless communication device is cancelled.

5. A wireless communication method to be performed by a first wireless communication device, the method comprising:

broadcasting a beacon;

receiving an association request signal from a second wireless communication device receiving the beacon; and

transmitting an acknowledgement (ACK) signal to the second wireless communication device in response to the association request signal,

wherein the ACK signal comprises device identifier (ID) information on a device ID allocated to the second wireless communication device by the first wireless communication device.

6. The method of claim 5, wherein the device ID information is stored in a DestID field of the ACK signal.

7. The method of claim 5, wherein the second wireless communication device is configured to determine the device ID of the second wireless communication device based on the device ID information comprised in the ACK signal.

8. The method of claim 7, wherein the association request signal comprises UnassocID information,

wherein, when the device ID information and the UnassocID information differ from each other, the second wireless communication device is configured to determine the device ID of the second wireless communication device based on the device IL) information.

9. The method of claim 5, further comprising:

transmitting a beacon in which a superframe duration (SD) is set to be infinite, when the first wireless communication device is associated with the second wireless communication device.

10. (canceled)

11. (canceled)

12. (canceled)

13. (canceled)

14. (canceled)

15. (canceled)

16. (canceled)

17. A wireless communication method to be performed by a first wireless communication device, the method comprising:

broadcasting a first beacon using a first physical layer (PHY) mode; and

broadcasting a second beacon using a second PHY mode,

wherein, when association with a second wireless communication device is established based on one of the first beacon and the second beacon, use of a PHY mode that is not used for the association is suspended.
