Abstract

A wireless local area network (LAN) communication method that includes adaptively determining whether to apply a piggyback according to a communication environment, and transmitting a frame containing two or more kinds of information according to the result of the determination.

Claims

1. A wireless local area network (LAN) communication method, comprising:

adaptively determining whether or not to apply a piggyback according to a communication environment; and

transmitting a frame containing two or more kinds of information according to a result of the determination.

2. The method of claim 1, wherein the determination is performed based on information about a target station to which the frame is to be sent.

3. The method of claim 2, wherein the information about the target station contains information about whether the frame is being successively sent to the same target station.

4. The method of claim 1, wherein the determination is performed based on information about characteristics of data to be transmitted.

5. The method of claim 4, wherein the information about the characteristics of data to be transmitted contains information about whether a size of a frame is less than a predetermined threshold.

6. The method of claim 1, wherein the determination is performed based on information about channel status.

7. The method of claim 6, wherein the information about the channel status contains information about whether a frame loss rate is less than a predetermined threshold.

8. The method of claim 6, wherein the information about channel status contains information about whether a derived received signal strength indication (RSSI) is greater than a second predetermined threshold.

9. The method of claim 1, wherein the frame containing two or more kinds of information includes one of data+poll, data+ACK, data+poll+ACK, and poll+ACK frames.

10. The method of claim 1, wherein transmission is performed in a Point Coordination Function (PCF) mode.

11. A recording medium on which is recorded a program for performing a wireless local area network (LAN) communication method, said method comprising:

adaptively determining whether or not to apply a piggyback according to a communication environment; and

transmitting a frame containing two or more kinds of information according to a result of the determination.

12. The recording medium according to claim 11, wherein the determination is performed based on information about a target station to which the frame is to be sent.

13. The recording medium according to claim 12, wherein the information about the target station contains information about whether the frame is being successively sent to the same target station.

14. The recording medium according to claim 11, wherein the determination is performed based on information about characteristics of data to be transmitted.

15. The recording medium according to claim 14, wherein the information about the characteristics of data to be transmitted contains information about whether a size of a frame is less than a predetermined threshold.

16. The recording medium according to claim 11, wherein the determination is performed based on information about channel status.

17. The recording medium according to claim 16, wherein the information about the channel status contains information about whether a frame loss rate is less than a predetermined threshold.

18. The recording medium according to claim 16, wherein the information about channel status contains information about whether a derived received signal strength indication (RSSI) is greater than a second predetermined threshold.

19. The recording medium according to claim 11, wherein the frame containing two or more kinds of information includes one of data+poll, data+ACK, data+poll+ACK, and poll+ACK frames.

20. The recording medium according to claim 11, wherein transmission is performed in a Point Coordination Function (PCF) mode.
