Abstract

Systems and methods for dynamically adapting channel access or transmission parameters based upon an identified channel access parameter or previously used transmission parameter are disclosed. In an aspect, an electronic device for communication over a wireless network is disclosed. The electronic device comprises a processor configured to generate a message that identifies one rule of a plurality of rules. Each of the plurality of rules defines a process for adapting a value of a communication parameter based on an identified channel access parameter. Also, each of the plurality of rules provides a particular quality of service and a particular priority for communication with the electronic device. The electronic device further comprises a transceiver configured to transmit the message to a station.

generate a message indicating that a station is to determine a quality of service priority value for the station'"'"'s transmissions to the electronic device as a logarithmic function of a transmission opportunity (TXOP) limit or a transmission opportunity (TXOP) duration, wherein the quality of service priority value defines one or more of a contention window minimum (CWmin) value, a corresponding contention window maximum (CWmax) value, and an arbitration infra-frame spacing number (AIFSN) value for the station; and

a transceiver configured to transmit the message to the station.

2. The electronic device of claim 1, wherein the station'"'"'s determination of the quality of service priority value for the station'"'"'s transmissions to the electronic device applies to each packet of data transmitted from the station.

3. The electronic device of claim 1, wherein the station'"'"'s determination of the quality of service priority value for the station'"'"'s transmissions to the electronic device applies to all packets of data transmitted from the station within a single transmit opportunity.

4. The electronic device of claim 1, wherein the message indicates the quality of service priority value is to be a same value for at least two stations in communication with the electronic device.

5. The electronic device of claim 1, wherein the message further indicates the station is to determine a transmission opportunity for the station as a function of a rate of transmission of data from the station to the electronic device.

6. The electronic device of claim 1, wherein the message indicates the station is to determine the quality of service priority value for transmitting data to the electronic device as a convex function of the transmission opportunity limit or the transmission opportunity duration.

7. The electronic device of claim 1, wherein the transceiver is configured to transmit the message to the station in a beacon frame.

8. The electronic device of claim 1, wherein the transceiver is configured to transmit the message to the station in an association response frame.

9. The electronic device of claim 1, wherein the message indicates the station is to determine the quality of service priority value as a function of a transmission parameter of the station, the transmission parameter selected from a group including a transmit power and a retransmission limit.

10. The electronic device of claim 1, further comprising:

generating a second message, the second message indicating the station compares a particular clear channel assessment threshold included in the second message to an energy level of the wireless network to determine whether the wireless network is busy; and

transmitting the second message to the station.

11. The electronic device of claim 1, further comprising:

generating a second message, the second message indicating the station determines a size of a packet transmission as a function of a size of a packet previously transmitted by the station; and

transmitting the second message to the station.

12. The electronic device of claim 1, further comprising:

generating a second message, the second message indicating the station determines a rate for station transmissions to the electronic device as a function of a rate previously transmitted by the station to the electronic device; and

transmitting the second message to the station.

13. The electronic device of claim 1, further comprising:

generating a second message, the second message indicating the station determines, at the station, the quality of service priority value for station transmissions to the electronic device as a function of a transmission queue length of the station; and

transmitting the second message to the station.

14. The electronic device of claim 1, further comprising:

generating a second message, the second message indicating the station determines, at the station, the quality of service priority value for station transmissions to the electronic device as a function of an average of previous queue lengths within a time period; and

transmitting the second message to the station.

15. The electronic device of claim 1, wherein the logarithmic function is of the transmission opportunity limit.

16. The electronic device of claim 1, wherein the logarithmic function is of the transmission opportunity duration.

17. A station for communication over a wireless network, comprising:

a transceiver configured to receive a message from an electronic device that indicates that the station is to determine a quality of service priority value for the station'"'"'s transmissions to the electronic device as a logarithmic function of a transmission opportunity limit or a transmission opportunity duration, wherein the quality of service priority value defines one or more of a contention window minimum (CWmin) value, a corresponding contention window maximum (CWmax) value, and an arbitration infra-frame spacing number (AIFSN) value for the station; and

a processor configured to determine the quality of service priority value according to the message,

wherein the transceiver is configured to transmit packets of data to the electronic device using the determined quality of service priority value.
