Systems and methods of reporting buffer status for wireless peer-to-peer (P2P) traffic
A first device may include one or more processors. The one or more processors may be configured to generate a first frame including buffer status data corresponding to wireless traffic between the first device and a second device. Each of the first device and the second device may not be an access point. The one or more processors may be configured to wirelessly transmit, via a transceiver, the generated first frame to an access point in a wireless local area network (WLAN).
1 . A first device comprising:
one or more processors configured to:
generate a first frame including buffer status data corresponding to wireless traffic between the first device and a second device, wherein each of the first device and the second device is not an access point; and
wirelessly transmit, via a transceiver, the generated first frame to an access point in a wireless local area network (WLAN), wherein:
the first frame includes a quality of service (QoS) control field that includes a first field, and
in generating the first frame, the one or more processors are configured to set the first field to a value indicating that the buffer status data included in the first frame relates to wireless peer-to-peer (p2p) traffic.
2 . The first device according to claim 1 , wherein the one or more processors are further configured to:
wirelessly receive, via the transceiver from the access point, a second frame; and
in response to the second frame, generate the first frame.
3 . The first device according to claim 1 , wherein the wireless traffic comprises peer-to-peer (p2p) traffic between the first device and the second device.
4 . The first device according to claim 1 , wherein:
the first frame includes a control identifier field, and
in generating the first frame, the one or more processors are configured to set the control identifier field to a value indicating a buffer status report frame.
5 . The first device according to claim 1 , wherein:
the first frame includes a bitmap field that includes a plurality of bits corresponding to a plurality of access categories, and
in generating the first frame, the one or more processors are configured to set each of the plurality of bits to a first value indicating that there is no traffic associated with an access category corresponding to the bit.
6 . The first device according to claim 5 , wherein:
the first frame includes a number of traffic identifiers field indicating a number of traffic identifiers for which there is buffered traffic, and
in generating the first frame, the one or more processors are configured to set the number of traffic identifiers field to a second value indicating that the number of traffic identifiers for which there is buffered traffic is zero.
7 . The first device according to claim 1 , wherein:
the QoS control field includes a second field, and
in generating the first frame, the one or more processors are configured to set the second field to a value indicating a queue size of the wireless traffic between the first device and the second device.
8 . The first device according to claim 1 , wherein:
the first frame includes a control identifier field, and
in generating the first frame, the one or more processors are configured to set the control identifier field to a value indicating a peer-to-peer (p2p) buffer status report frame.
9 . The first device according to claim 8 , wherein
the first frame includes a queue size field, and
in generating the first frame, the one or more processors are configured to set the queue size field to a value indicating a queue size of the wireless traffic between the first device and a second device.
10 . A method comprising:
generating, by a first device, a first frame including buffer status data corresponding to wireless traffic between the first device and a second device, wherein each of the first device and the second device is not an access point; and
wirelessly transmitting, via a transceiver of the first device, the generated first frame to an access point in a wireless local area network (WLAN), wherein:
the first frame includes a quality of service (QOS) control field that includes a first field, and
generating the first frame comprises setting the first field to a value indicating that the buffer status data included in the first frame relates to wireless peer-to-peer (p2p) traffic.
11 . The method according to claim 10 , further comprising:
wirelessly receiving, via the transceiver from the access point, a second frame; and
in response to the second frame, generating the first frame.
12 . The method according to claim 10 , wherein the wireless traffic comprises peer-to-peer (p2p) traffic between the first device and the second device.
13 . The method according to claim 10 , wherein:
the first frame includes a control identifier field, and
generating the first frame comprises setting the control identifier field to a value indicating a buffer status report frame.
14 . The method according to claim 10 , wherein:
the first frame includes a bitmap field that includes a plurality of bits corresponding to a plurality of access categories, and
generating the first frame comprises setting each of the plurality of bits to a first value indicating that there is no traffic associated with an access category corresponding to the bit.
15 . The method according to claim 14 , wherein:
the first frame includes a number of traffic identifiers field indicating a number of traffic identifiers for which there is buffered traffic, and
generating the first frame comprises setting the number of traffic identifiers field to a second value indicating that the number of traffic identifiers for which there is buffered traffic is zero.
16 . The method according to claim 10 , wherein:
the QoS control field includes a second field, and
generating the first frame comprises setting the second field to a value indicating a queue size of the wireless traffic between the first device and the second device.
17 . The method according to claim 10 , wherein:
the first frame includes a control identifier field, and
generating the first frame comprises setting the control identifier field to a value indicating a peer-to-peer (p2p) buffer status report frame.
18 . The method according to claim 17 , wherein
the first frame includes a queue size field, and
generating the first frame comprises setting the queue size field to a value indicating a queue size of the wireless traffic between the first device and a second device.
