1. A method for wireless communication by a wireless access point (AP), comprising:
obtaining one or more service-level agreement (SLA) parameters for each traffic flow of a plurality of traffic flows, each traffic flow including a plurality of packets intended for a respective station (STA) of a plurality of STAs associated with the AP, the one or more SLA parameters indicating at least a delay bound for each of the traffic flows;
receiving one or more first packets of a first traffic flow of the plurality of traffic flows;
delaying transmission of the first packets of the first traffic flow for a delay period based at least in part on an amount of data carried in the first packets of the first traffic flow being less than a first threshold; and
during the delay period:
receiving one or more second packets of the first traffic flow while also receiving packets of a second traffic flow of the plurality of traffic flows;
grouping the second traffic flow with the first traffic flow for a multi-user (MU) multiple-input multiple output (MIMO) transmission based at least in part on an amount of data carried in the first and second packets of the first traffic flow being greater than the first threshold and an amount of data carried in the packets of the second traffic flow being greater than a second threshold;
and transmitting the first and second packets of the first traffic flow with the packets of the second traffic flow as an MU-MIMO communication.
