Rate control based on round-trip time

A method of wireless communication performed by a server device, comprising:

• receiving, during a first time window, information indicating a plurality of client round-trip times (CRTTs) associated with a client device;
• computing a plurality of network round-trip times (NRTTs) based at least in part on the plurality of CRTTs, each NRTT in the plurality of NRTTs corresponding to a respective CRTT in the plurality of CRTTs;
• computing one or more NRTT metrics for the first time window using the plurality of NRTTs;
• configuring values for one or more NRTT metric thresholds;
• increasing a value of an upper NRTT standard deviation threshold and a value of a lower NRTT standard deviation threshold based at least in part on that a current network metric is greater than a reference network metric;
• and
• selectively adjusting a bitrate used for a transmission to the client device based at least in part on a determination of whether the one or more NRTT metrics satisfy the one or more NRTT metric thresholds.

A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a server device, cause the server device to:
• receive, during a first time window, information indicating a plurality of client round-trip times (CRTTs) associated with a client device;
• compute a plurality of network round-trip times (NRTTs) based at least in part on the plurality of CRTTs, each NRTT in the plurality of NRTTs corresponding to a respective CRTT in the plurality of CRTTs;
• compute one or more NRTT metrics for the first time window using the plurality of NRTTs;
• configure values for one or more NRTT metric thresholds;
• increase a value of an upper NRTT standard deviation threshold and a value of a lower NRTT standard deviation threshold based at least in part on that a current network metric is greater than a reference network metric;
• and
• selectively adjust a bitrate used for a transmission to the client device based at least in part on a determination of whether the one or more NRTT metrics satisfy the one or more NRTT metric thresholds.
