Abstract

Systems, methods, and devices for communicating packets having a plurality of types are described herein. In some aspects, the packets include a compressed MAC header. In some aspects the packets include an acknowledgment (ACK) frame. The fields included in a particular packet type may be based on the type of information to be communicated to the receiving device.

First claim

What is claimed is:

1. A method of communicating in a wireless network, the method comprising:
generating a packet including a local identifier of either a transmitter of the packet or a receiver of the packet and a media access control address of the other of the transmitter and the receiver, the local identifier identifying either the transmitter or the receiver within a basic service set containing at least one of the transmitter or the receiver, the media access control address identifying either the transmitter or the receiver globally;
selecting one of the local identifier or the media access control address to identify the transmitter based on a link type for transmitting the packet, the link type being one of a downlink, an uplink, or a direct link, the selecting comprising:
selecting the local identifier to identify the receiver and the media access control address to identify the transmitter when the link type is the downlink;
selecting the local identifier to identify the transmitter and the media access control address to identify the receiver when the link type is the uplink; and
selecting the local identifier to identify the transmitter and the media access control address to identify the receiver when the link type is the direct link; and

transmitting the packet from the transmitter to the receiver.

2. The method of claim 1 , wherein the local identifier comprises an association identifier.

3. The method of claim 2 , wherein the association identifier comprises 13 bits and the media access control address comprises 48 bits.

4. The method of claim 1 , wherein the packet further includes information indicating the link type.

5. The method of claim 4 , wherein the information is included in at least one of a to-distribution system field and a from-distribution system field.

6. The method of claim 1 , wherein an identifier of the receiver precedes an identifier of the transmitter in the packet.

7. The method of claim 1 , wherein the local identifier and the media access control address in combination uniquely define a pair consisting of the receiver and the transmitter.

8. The method of claim 1 , wherein the packet includes a field indicating if at least one of a destination address field and a source address field is present in the packet.

9. The method of claim 8 , wherein the field that identifies whether the packet includes at least one of a destination address field and a source address field is one or more of a type field and a subtype field of a frame control field.

10. The method of claim 8 , wherein the field that identifies whether the packet includes at least one of a destination address field and a source address field is a single bit.

11. The method of claim 1 , wherein the packet includes a field that identifies whether the packet includes a compressed header or an uncompressed header.

12. The method of claim 11 , wherein the field that identifies whether the packet includes a compressed header or an uncompressed header is a protocol version field.

13. The method claim 11 , wherein the field that identifies whether the packet includes a compressed header or an uncompressed header is one or more of a type field and a subtype field of a frame control field.

14. The method of claim 1 , wherein the packet does not include at least one of a duration field, high throughput control field, and a quality of service control field.

15. The method of claim 1 , wherein the packet includes a sequence control field.

16. An apparatus for communicating in a wireless network, the apparatus comprising:
a processor configured to:
generate a packet including a local identifier of either a transmitter of the packet or a receiver of the packet and a media access control header of the other of the transmitter and the receiver, the local identifier identifying either the transmitter or the receiver within a basic service set containing at least one of the transmitter or the receiver, the media access control address identifying either the transmitter or the receiver globally, and
select one of the local identifier or the media access control address to identify the transmitter based on a link type for transmitting the packet, the link type being one of a downlink, an uplink, or a direct link, the selection comprising:
selecting the local identifier to identify the receiver and the media access control address to identify the transmitter when the link type is the downlink;
selecting the local identifier to identify the transmitter and the media access control address to identify the receiver when the link type is the uplink; and
selecting the local identifier to identify the transmitter and the media access control address to identify the receiver when the link type is the direct link; and

a transmitter configured to transmit the packet to the receiver.

17. The apparatus of claim 16 , wherein the local identifier comprises an association identifier.

18. The apparatus of claim 17 , wherein the association identifier comprises 13 bits and the media access control address comprises 48 bits.

19. The apparatus of claim 16 , wherein the packet further includes information indicating the link type.

20. The apparatus of claim 19 , wherein the information is included in at least one of a to-distribution system field and a from-distribution system field.

21. The apparatus of claim 16 , wherein an identifier of the receiver precedes an identifier of the transmitter in the packet.

22. The apparatus of claim 16 , wherein the local identifier and the media access control address in combination uniquely define a pair consisting of the receiver and the transmitter.

23. The apparatus of claim 16 , wherein the packet includes a field indicating if at least one of a destination address field and a source address field is present in the packet.

24. The apparatus of claim 23 , wherein the field that identifies whether the packet includes at least one of a destination address field and a source address field is one or more of a type field and a subtype field of a frame control field.

25. The apparatus of claim 23 , wherein the field that identifies whether the packet includes at least one of a destination address field and a source address field is a single bit.

26. The apparatus of claim 16 , wherein the packet includes a field that identifies whether the packet includes a compressed header or an uncompressed header.

27. The apparatus of claim 26 , wherein the field that identifies whether the packet includes a compressed header or an uncompressed header is a protocol version field.

28. The apparatus of claim 26 , wherein the field that identifies whether the packet includes a compressed header or an uncompressed header is one or more of a type field and a subtype field of a frame control field.

29. The apparatus of claim 16 , wherein the packet does not include at least one of a duration field, high throughput control field, and a quality of service control field.

30. The apparatus of claim 16 , wherein the packet includes a sequence control field.

31. An apparatus for communicating in a wireless network, the apparatus comprising:
means for generating a packet including a local identifier of either a transmitter of the packet or a receiver of the packet and a media access control address of the other of the
