Abstract

An example method may include determining a multi-user packet error rate associated with communications from a client device to a host device, the multi-user packet error rate based on a number of packets in a multi-user communication frame with an error. The method may also include sending a trigger from the host device to the client device to communicate via a second multi-user communication frame, the trigger identifying a transfer rate based on the multi-user packet error rate.

Claims (36)

1 . A method, comprising:

determining a first packet error rate associated with a first communication at a first uplink rate from a client device to a host device;

determining a second packet error rate associated with a second communication at a second uplink rate from the client device to the host device, wherein determining the second packet error rate comprises:

sending an initial trigger from the host device to the client device;

identifying an absence of any packets from the client device during a particular amount of time; and

based on the absence of any packets from the client device during the particular amount of time, attributing a number of packets in a previous communication to the second packet error rate;

determining that the second packet error rate is below a threshold error rate; and

sending a trigger from the host device to the client device to communicate via the second uplink rate based on the second packet error rate being below the threshold error rate.

2 . The method of claim 1 , wherein determining the first packet error rate comprises:

monitoring a sequence number of received packets;

detecting a gap in the sequence number of received packets;

identifying an absence of a packet indicating a start of a second protocol data unit; and

based on a first protocol data unit preceding the second protocol data unit being complete, attributing all packets in the gap to the first packet error rate.

3 . The method of claim 1 , wherein the first communication includes one of: a single-user uplink transmission, a multi-user uplink transmission, or an orthogonal frequency division multiple access (OFDMA) uplink transmission.

4 . The method of claim 1 , wherein the second communication includes one of: a single-user uplink transmission, a multi-user uplink transmission, or an orthogonal frequency division multiple access (OFDMA) uplink transmission.

5 . The method of claim 1 , wherein the threshold error rate relates to an Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard.

6 . The method of claim 1 , wherein the second packet error rate includes an uplink error rate.

7 . A system, comprising:

one or more processors; and

one or more non-transitory computer readable media containing instructions that, when executed by the one or more processors, cause the system to perform one or more operations, the operations comprising:

determine a first packet error rate associated with a first communication at a first uplink rate from a client device to a host device;

determine a second packet error rate associated with a second communication at a second uplink rate from the client device to the host device, wherein the operation to determine the second packet error rate comprises:

send an initial trigger from the host device to the client device;

identify an absence of any packets from the client device during a particular amount of time; and

attribute, based on the absence of any packets from the client device during the particular amount of time, a number of packets in a previous communication to the second packet error rate;

determine that the second packet error rate is below a threshold error rate; and

send a trigger from the host device to the client device to communicate via the second uplink rate based on the second packet error rate being below the threshold error rate.

8 . The system of claim 7 , wherein the operation to determine the first packet error rate comprises:

monitor a sequence number of received packets;

detect a gap in the sequence number of received packets;

identify an absence of a packet indicating a start of a second protocol data unit; and

based on a first protocol data unit preceding the second protocol data unit being complete, attribute all packets in the gap to the first packet error rate.

9 . The system of claim 7 , wherein the first communication includes one of: a single-user uplink transmission, a multi-user uplink transmission, or an orthogonal frequency division multiple access (OFDMA) uplink transmission.

10 . The system of claim 7 , wherein the second communication includes one of: a single-user uplink transmission, a multi-user uplink transmission, or an orthogonal frequency division multiple access (OFDMA) uplink transmission.

11 . The system of claim 7 , wherein the threshold error rate relates to an Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard.

12 . The system of claim 7 , wherein the second packet error rate includes an uplink error rate.
