Abstract

Claims (45)

1 . A device comprising:

one or more processors configured to:

determine a first traffic identifier of a first wireless traffic stream, from a plurality of traffic identifiers;

generate a first frame including the first traffic identifier, the first frame to trigger a receiver device to send a response frame that comprises quality of service (QOS) data corresponding to the first wireless traffic stream; and

wirelessly transmit, via a transmitter, the generated first frame to the receiver device,

wherein in generating the first frame, the one or more processors are configured to:

determine whether a first field of the first frame is set to a first value; and

in response to determining that the first field is set to the first value, set a second field of the first frame to indicate the first traffic identifier.

2 . The device according to claim 1 , wherein the first field is a subfield of a user information field that is associated with a particular user or the receiving device.

3 . The device according to claim 1 , wherein in generating the first frame, the one or more processors are configured to:

determine whether a third field of the first frame is set to a second value; and

in response to determining that the first field is set to the first value and the third field is set to the second value, set a first bit of a fourth field of the first frame to indicate the first traffic identifier.

4 . The device according to claim 3 , wherein the fourth field of the first frame comprises a plurality of bits each corresponding to a traffic identifier associated with one of a plurality of traffic categories.

5 . The device according to claim 1 , wherein in generating the first frame, the one or more processors are configured to:

set a frame type field of the first frame to a type indicating a trigger frame including one or more traffic identifiers; and

set a traffic identifier field of the first frame to the first traffic identifier.

6 . The device according to claim 1 , wherein in generating the first frame, the one or more processors are configured to:

set a frame type field of the first frame to a type indicating a trigger frame including one or more traffic identifiers; and

set a first bit of a traffic identifier bitmap field of the first frame to indicate the first traffic identifier.

7 . The device according to claim 6 , wherein the traffic identifier bitmap field of the first frame comprises a plurality of bits each corresponding to a traffic identifier associated with one of a plurality of traffic categories.

8 . The device according to claim 1 , wherein in generating the first frame, the one or more processors are configured to:

set a second field of the first frame to the first traffic identifier, when the first frame is to be wirelessly transmitted during a service period (SP) of a target wake time (TWT) schedule.

9 . The device according to claim 8 , wherein the TWT schedule is a restricted TWT schedule.

10 . A method comprising:

determining, by a first device, a first traffic identifier of a first wireless traffic stream, from a plurality of traffic identifiers;

generating a first frame including the first traffic identifier, the first frame to trigger a receiver device to send a response frame that comprises quality of service (QOS) data corresponding to the first wireless traffic stream; and

wirelessly transmitting, via a transmitter, the generated first frame to the receiver device,

wherein generating the first frame comprises:

determining whether a first field of the first frame is set to a first value; and

in response to determining that the first field is set to the first value, setting a second field of the first frame to indicate the first traffic identifier.

11 . The method according to claim 10 , wherein the first field is a subfield of a user information field that is associated with a particular user or the receiving device.

12 . The method according to claim 10 , wherein generating the first frame comprises:

determining whether a third field of the first frame is set to a second value; and

in response to determining that the first field is set to the first value and the third field is set to the second value, setting a first bit of a fourth field of the first frame to indicate the first traffic identifier.

13 . The method according to claim 12 , wherein the fourth field of the first frame comprises a plurality of bits each corresponding to a traffic identifier associated with one of a plurality of traffic categories.

14 . The method according to claim 10 , wherein generating the first frame comprises:

setting a frame type field of the first frame to a first type indicating a trigger frame including one or more traffic identifiers; and

setting a traffic identifier field of the first frame to the first traffic identifier.

15 . The method according to claim 10 , wherein generating the first frame comprises:

setting a frame type field of the first frame to a type indicating a trigger frame including one or more traffic identifiers; and

setting a first bit of a traffic identifier bitmap field of the first frame to indicate the first traffic identifier.

16 . The method according to claim 15 , wherein the traffic identifier bitmap field of the first frame comprises a plurality of bits each corresponding to a traffic identifier associated with one of a plurality of traffic categories.

17 . The method according to claim 10 , wherein generating the first frame comprises:

setting a second field of the first frame to the first traffic identifier, when the first frame is to be wirelessly transmitted during a service period (SP) of a target wake time (TWT) schedule.

18 . The method according to claim 17 , wherein the TWT schedule is a restricted TWT schedule.
