EXTENSION OF SOFT AP CAPABILITIES BASED ON TRIGGER FRAME
Disclosed herein are related to a system and a method of communication. In one aspect, a first device receives a trigger frame via a unicast transmission from a second device configured to schedule the first device for an uplink transmission by the first device. The trigger frame may include a common field and a user field. The common field may include a first set of fields, and the user field may include a second set of fields. In one aspect, the first device generates a response frame, in response to a first subset of the first set of fields and a second subset of the second set of fields, and transmits the response frame to the second device. The first device may generate the response frame, irrespective of a third subset of the first set of fields and a fourth subset of the second set of fields.

receiving, by a first device, a trigger frame via a unicast transmission from a second device configured to schedule the first device for an uplink transmission by the first device, the trigger frame including a common field and a user field, the common field including a first set of fields, the user field including a second set of fields;
generating, by the first device, a response frame, in response to a first subset of the first set of fields and a second subset of the second set of fields; and
transmitting, by the first device to the second device, the response frame.
2 . The method of claim 1 , wherein generating, by the first device, the response frame includes:
generating, by the first device, the response frame, irrespective of a third subset of the first set of fields and a fourth subset of the second set of fields.
3 . The method of claim 1 , wherein the first subset of the first set of fields includes a type field indicating a type of action to trigger, and a length field indicating a length of the response frame.
4 . The method of claim 3 , wherein the type of action includes one of an uplink traffic scheduling, a buffer status report poll, or a bandwidth query report poll.
5 . The method of claim 1 , wherein the second subset of the second set of fields includes an identification field identifying the first device.
6 . The method of claim 1 , wherein the second device is a soft enabled access point, a mobile access point, or peer to peer group owner (P2P-GO).
7 . The method of claim 1 , wherein the first device comprises a head wearable display (HWD), a controller, a smart watch, or a mobile device.
8 . The method of claim 1 , wherein the response frame is transmitted via a single user physical layer convergence protocol (PLCP) protocol data unit (SU PPDU).
9 . A first device comprising:
one or more processors configured to:
receive a trigger frame via a unicast transmission from a second device configured to schedule the first device for an uplink transmission by the first device, the trigger frame including a common field and a user field, the common field including a first set of fields, the user field including a second set of fields,
generate a response frame, in response to a first subset of the first set of fields and a second subset of the second set of fields, and
transmit the response frame to the second device.
10 . The first device of claim 9 , wherein the one or more processors are configured to generate the response frame, irrespective of a third subset of the first set of fields and a fourth subset of the second set of fields.
11 . The first device of claim 9 , wherein the first subset of the first set of fields includes a type field indicating a type of action to trigger, and a length field indicating a length of the response frame.
12 . The first device of claim 11 , wherein the type of action includes one of an uplink traffic scheduling, a buffer status report poll, or a bandwidth query report poll.
13 . The first device of claim 9 , wherein the second subset of the second set of fields includes an identification field identifying the first device.
14 . The first device of claim 9 , wherein the second device is a soft enabled access point, a mobile access point, or peer to peer group owner (P2P-GO).
15 . The first device of claim 9 , wherein the first device comprises a head wearable display (HWD), a controller, a smart watch, or a mobile device.
16 . The first device of claim 9 , wherein the response frame is transmitted via a single user physical layer conformance procedure (PLCP) protocol data unit (SU PPDU).
17 . A non-transitory computer readable medium comprising instructions when executed by one or more processors of a first device cause the one or more processors to:
receive a trigger frame via a unicast transmission from a second device configured to schedule the first device for an uplink transmission by the first device, the trigger frame including a common field and a user field, the common field including a first set of fields, the user field including a second set of fields,
generate a response frame, in response to a first subset of the first set of fields and a second subset of the second set of fields, and
transmit the response frame to the second device.
18 . The non-transitory computer readable medium of claim 17 , wherein the instructions when executed by the one or more processors cause the one or more processors to generate the response frame, irrespective of a third subset of the first set of fields and a fourth subset of the second set of fields.
19 . The non-transitory computer readable medium of claim 17 , wherein the first subset of the first set of fields includes a type field indicating a type of action to trigger, and a length field indicating a length of the response frame.
20 . The non-transitory computer readable medium of claim 19 , wherein the type of action includes one of an uplink traffic scheduling, a buffer status report poll, or a bandwidth query report poll.
