Abstract

A medium access control (MAC) frame may have a MAC header that includes two address fields and a MAC frame version indicator. The MAC header may also include control information that indicates a presence of a third address field in the MAC header. A time interval for transmission of the MAC frame may be determined by multiplying a duration value in a first message field by a multiplier value in a second message field.

Claims

1. A wireless transmit/receive unit (WTRU) comprising:

a processor configured to generate a medium access control (MAC) frame having a MAC header;

wherein the MAC header includes at least two address fields and a MAC frame version indicator;

wherein the MAC header comprises control information that indicates presence of a third address field in the MAC header;

wherein a time interval for transmission of the MAC frame is determined by multiplying a duration value in a first message field by a multiplier value in a second message field; and

a transceiver configured to transmit the MAC frame during the time interval.

2. The WTRU of claim 1, wherein the MAC header further comprises an option subfield, wherein the option subfield comprises a fragmentation field, a transmission opportunity (TXOP) field, a very high throughput (VHT) control field, or a MAC Header (MH) option field.

3. The WTRU of claim 2, wherein the MH option field indicates different types of MAC headers.

4. The WTRU of claim 1 further comprising:

the processor configured to negotiate a MAC header type with another WTRU.

5. The WTRU of claim 1 further comprising:

the processor configured to negotiate compression of the MAC header with another WTRU.

6. The WTRU of claim 1, wherein the MAC header further comprises a sequence control field.

7. The WTRU of claim 1 further comprising:

the processor configured to negotiate at least two short MAC header types with another WTRU; and

wherein the at least two short MAC header types are selected based on a traffic stream characteristic or quality of service (QoS).

8. The WTRU of claim 1, wherein the MAC header includes a protected frame bit that indicates there is buffered data at the WTRU.

9. A method performed by a wireless transmit/receive unit (WTRU), the method comprising:

generating, by the WTRU, a medium access control (MAC) frame having a MAC header;

wherein the MAC header includes at least two address fields and a MAC frame version indicator;

wherein the MAC header comprises control information that indicates presence of a third address field in the MAC header;

wherein a time interval for transmission of the MAC frame is determined by multiplying a duration value in a first message field by a multiplier value in a second message field; and

transmitting, by the WTRU, the MAC frame during the time interval.

10. The method of claim 9, wherein the MAC header further comprises an option subfield, wherein the option subfield comprises a fragmentation field, a transmission opportunity (TXOP) field, a very high throughput (VHT) control field, or a MAC Header (MH) option field.

11. The method of claim 10, wherein the MH option field indicates different types of MAC headers.

12. The method of claim 9 further comprising:

negotiating, by the WTRU, a MAC header type with another WTRU.

13. The method of claim 9 further comprising:

negotiating, by the WTRU, compression of the MAC header with another WTRU.

14. The method of claim 9, wherein the MAC header further comprises a sequence control field.

15. The method of claim 9 further comprising:

negotiating, by the WTRU, at least two short MAC header types with another WTRU; and

wherein the at least two short MAC header types are selected based on a traffic stream characteristic or quality of service (QoS).

16. The method of claim 9, wherein the MAC header includes a protected frame bit that indicates there is buffered data at the WTRU.
