SYSTEMS AND METHODS OF BUFFER STATUS REPORTING FOR TRANSMISSION STREAMS
A first device may include one or more processors. The one or more processors may be configured to wirelessly receive, via a transceiver from a second device, a first frame. The one or more processors may be configured to identify one or more traffic identifiers from a first field of the first frame. The one or more processors may be configured to generate a second frame including buffer status data of one or more wireless traffic streams corresponding to the one or more traffic identifiers. The one or more processors may be configured to wirelessly transmit, via the transceiver, the generated second frame to the second device.
1 . A first device comprising:
one or more processors configured to:
wirelessly receive, via a transceiver from a second device, a first frame;
identify one or more traffic identifiers from a first field of the first frame;
generate a second frame including buffer status data of one or more wireless traffic streams corresponding to the one or more traffic identifiers; and
wirelessly transmit, via the transceiver, the generated second frame to the second device.
2 . The first device according to claim 1 , wherein the second device is an access point, a soft access point or a peer device.
3 . The first device according to claim 1 , wherein in generating the second frame, the one or more processors are configured to:
set one or more bits of a traffic identifier bitmap field of the second frame to indicate the one or more traffic identifiers.
4 . The first device according to claim 3 , wherein the traffic identifier bitmap field of the second frame comprises a plurality of bits each corresponding to a traffic identifier associated with one of a plurality of traffic categories.
5 . The first device according to claim 1 , wherein in generating the second frame, the one or more processors are configured to:
set a first queue size field of the second frame to a highest queue size among one or more queue sizes of at least one wireless traffic streams associated with the one or more traffic identifiers.
6 . The first device according to claim 5 , wherein in generating the second frame, the one or more processors are configured to:
set a first traffic identifier field of the second frame to a traffic identifier corresponding to the highest queue size.
7 . The first device according to claim 1 , wherein in generating the second frame, the one or more processors are configured to:
set a second queue size field of the second frame to a total queue size of traffic associated with the one or more traffic identifiers.
8 . The first device according to claim 1 , wherein in identifying the one or more traffic identifiers from the first field of the first frame, the one or more processors are configured to:
determine whether a frame type field of the first frame is a first type indicating a buffer status trigger frame;
identify the first field as a traffic identifier bitmap field; and
identify the one or more traffic identifiers from one or more bits of the traffic identifier bitmap field set to a defined value.
9 . The first device according to claim 8 , wherein the frame type field of the first frame is a subfield of a common information field that is shared among a plurality of users or devices.
10 . The first device according to claim 8 , wherein the frame type field of the first frame indicates a type associated with a trigger frame.
11 . A method comprising:
wirelessly receiving, by a first device from a second device, a first frame;
identifying, by the first device, one or more traffic identifiers from a first field of the first frame;
generating, by the first device, a second frame including buffer status data of one or more wireless traffic streams corresponding to the one or more traffic identifiers; and
wirelessly transmitting, by the first device, the generated second frame to the second device.
12 . The method according to claim 11 , wherein the second device is an access point, a soft access point or a peer device.
13 . The method according to claim 11 , wherein generating the second frame comprises:
setting one or more bits of a traffic identifier bitmap field of the second frame to indicate the one or more traffic identifiers.
14 . The method according to claim 13 , wherein the traffic identifier bitmap field of the second frame comprises a plurality of bits each corresponding to a traffic identifier associated with one of a plurality of traffic categories.
15 . The method according to claim 11 , wherein generating the second frame comprises:
setting a first queue size field of the second frame to a highest queue size among one or more queue sizes of at least one wireless traffic streams associated with the one or more traffic identifiers.
16 . The method according to claim 15 , wherein generating the second frame comprises:
setting a first traffic identifier field of the second frame to a traffic identifier corresponding to the highest queue size.
17 . The method according to claim 11 , wherein generating the second frame comprises:
setting a second queue size field of the second frame to a total queue size of traffic associated with the one or more traffic identifiers.
18 . The method according to claim 11 , wherein identifying the one or more traffic identifiers from the first field of the first frame comprises:
determining whether a frame type field of the first frame is a first type indicating a buffer status trigger frame;
identifying the first field as a traffic identifier bitmap field; and
identifying the one or more traffic identifiers from one or more bits of the traffic identifier bitmap field set to a defined value.
19 . The method according to claim 18 , wherein the frame type field of the first frame is a subfield of a common information field that is shared among a plurality of users or devices.
20 . The method according to claim 18 , wherein the frame type field of the first frame indicates a type associated with a trigger frame.
