1. An apparatus, comprising:
a memory; and
logic for a station (STA), at least a portion of the logic comprised in circuitry coupled to the memory, the logic to:
receive a frame from an access point (AP) addressed to more than one associated STAs, wherein the frame comprises, for each of the more than one associated STAs, a resource unit allocation and a traffic identifier (TID) limit, wherein the frame comprises a trigger frame, wherein the resource unit allocation comprises different orthogonal frequency division multiple access (OFDMA) resource units for each of the more than one associated STAs;
identify, from the frame, the TID limit for the STA, wherein the TID limit for the STA comprises a number of TIDs that can be aggregated by the STA in an aggregate medium access control (MAC) protocol data unit (A-MPDU) for which the STA can request immediate response via acknowledgement policy fields;
generate the A-MPDU for transmission to the AP during an uplink (UL) transmission interval in response to the frame, the A-MPDU comprising MAC protocol data units (MPDUs) associated with multiple TIDs;
wherein a total number of TIDs in the A-MPDU having values in the acknowledgment policy fields indicating that immediate acknowledgment is requested, does not exceed the TID limit; and
cause transmission of the A-MPDU.
