Systems and methods of configuring traffic specification for wireless communication
Disclosed herein are systems and methods directed to configuring traffic specification for wireless communication. In one aspect, a first wireless communication device may configure a bitmap indicating a plurality of traffic identifiers (TIDs) sharing a traffic specification (TSPEC) element. The first wireless communication device may send a message including the bitmap to a second wireless communication device.
1. A method comprising:
configuring, by a first wireless communication device, a traffic specification (TSPEC) element including a plurality of quality of service (QOS) attributes, a field indicating a presence or absence of a bitmap, and the bitmap which indicates at least some of a plurality of traffic identifiers (TIDs) sharing the QoS attributes included in the TSPEC element; and
sending, by the first wireless communication device, a message to a second wireless communication device, the message comprising the TSPEC element including the bitmap, the message including the field set to a predefined value to indicate that the bitmap contains valid information.
2. The method of claim 1 , wherein the field being set to the predefined value, causes the second wireless communication device to ignore a traffic stream identifier associated with the TSPEC element.
3. The method of claim 1 , wherein the message includes a direction subfield that indicates a direction of the plurality of TIDs.
4. The method of claim 3 , wherein the direction subfield indicates one of: sending traffic in an uplink direction, sending traffic in a downlink direction, sending bidirectional traffic, or sending direct link traffic.
5. The method of claim 4 , comprising:
causing the second wireless communication device to ignore the plurality of TIDs when the direction subfield indicates sending direct link traffic, and the direct link traffic is to be sent during a service period of a restricted target wake time.
6. The method of claim 1 , wherein the second wireless communication device comprises an access point or a station device.
7. The method of claim 1 , wherein the TSPEC element includes characteristics that are shared by the plurality of TIDs.
8. A first wireless communication device comprising:
at least one processor configured to configure traffic specification (TSPEC) element including a plurality of quality of service (QOS) attributes, a field indicating a presence or absence of a bitmap, and the bitmap which indicates at least some of a plurality of traffic identifiers (TIDs) sharing QoS attributes included in the TSPEC element; and
a transmitter configured to send a message comprising the TSPEC element including the bitmap to a second wireless communication device, the message including the field set to a predefined value to indicate that the bitmap contains valid information.
9. The first wireless communication device of claim 8 , wherein the field being set to the predefined value, causes the second wireless communication device to ignore a traffic stream identifier associated with the TSPEC element.
10. The first wireless communication device of claim 8 , wherein the message includes a direction subfield that indicates a direction of the plurality of TIDs, wherein the direction subfield indicates one of: sending traffic in an uplink direction, sending traffic in a downlink direction, sending bidirectional traffic, or sending direct link traffic.
11. The first wireless communication device of claim 10 , wherein the direction subfield is configured to cause the second wireless communication device to ignore the plurality of TIDs when the direction subfield indicates sending direct link traffic, and the direct link traffic is to be sent during a service period of a restricted target wake time.
12. A method comprising:
receiving, by a second wireless communication device from a first wireless communication device, a message comprising a traffic specification (TSPEC) element including a plurality of quality of service (QOS) attributes, a field indicating a presence or absence of a bitmap, and the bitmap, wherein the field is set to a predefined value to indicate that the bitmap contains valid information,
wherein the bitmap indicates at least some of a plurality of traffic identifiers (TIDs) sharing QoS attributes included in the TSPEC element.
13. The method of claim 12 , comprising:
determining, by the second wireless communication device, to ignore a traffic stream identifier associated with the TSPEC element, when the field is set to the predefined value.
14. The method of claim 12 , wherein the message includes a direction subfield that indicates a direction of the plurality of TIDs.
15. The method of claim 14 , wherein the direction subfield indicates one of: sending traffic in an uplink direction, sending traffic in a downlink direction, sending bidirectional traffic, or sending direct link traffic.
16. The method of claim 15 , comprising:
determining, by the second wireless communication device, to ignore the plurality of TIDs, when the direction subfield indicates sending direct link traffic, and the direct link traffic is to be sent during a service period of a restricted target wake time.
17. A second wireless communication device, comprising a receiver and at least one processor configured to implement the method of claim 12 .
