1. An apparatus for wireless communications, comprising:
a processing system that includes one or more processors and memory that stores instructions, wherein the processing system is configured to cause the apparatus to:
obtain one or more packets associated with a traffic flow;
obtain at least one of one or more service-level agreement (SLA) parameters associated with the traffic flow, one or more attributes of the traffic flow, or one or more network parameters associated with a basic service set (BSS) that includes the apparatus;
provide an indication of whether the traffic flow is suitable for transmission over a wireless medium as a single-user (SU) multiple-input multiple output (MIMO) (SU-MIMO) communication, as a multi-user (MU) MIMO (MU-MIMO) communication, as an orthogonal frequency division multiple access (OFDMA) communication, or as a partial bandwidth (BW) MU-MIMO communication, the indication being based on one or more of the one or more SLA parameters, the one or more attributes of the traffic flow, or the one or more network parameters; and
initiate transmission of the one or more packets over the wireless medium based on the indication, wherein the processing system is further configured to cause the apparatus to:
output for transmission the one or more packets as a partial BW MU-MIMO transmission based on the traffic flow being associated with latency-sensitive traffic and a number of active latency-sensitive traffic flows being at least equal to a threshold number of traffic flows; or
output for transmission the one or more packets as an MU-MIMO transmission based on the traffic flow not being associated with latency-sensitive traffic and carrying more than a specified amount of data.
