Station (sta), access point (ap) and method for aggregation of data packets for uplink transmission

An apparatus of a high-efficiency (HE) station (STA), the STA configured for transmission of a multi-traffic identifier (TID) Aggregate Medium Access Control (MAC) Protocol Data Unit (A-MPDU) (multi-TID A-MPDU), the apparatus comprising:

• processing circuitry;
• and memory, the processing circuitry configured to:
• decode a trigger frame (TF) received from an access point (AP), the trigger frame comprising:
• a medium access control (MAC) protocol data unit (MPDU) multi-user (MU) (MPDU MU) spacing factor subfield;
• a traffic identifier (TID) aggregation limit subfield;
• and
• a preferred access class (AC) subfield,
• aggregate MPDUs into an aggregate MPDU (A-MPDU), wherein the MPDUs are selected for aggregation into the A-MPDU based on the TID aggregation limit subfield and the preferred AC subfield;
• and
• encode a high-efficiency (HE) trigger-based (TB) physical layer (PHY) protocol data unit (PPDU) (HE TB PPDU) for transmission to the AP in response to the trigger frame, the HE TB PPDU comprising the A-MPDU,
• wherein the TID aggregation limit subfield indicates a maximum number of TIDs to be aggregated by the STA in the A-MPDU, and
• wherein the preferred AC subfield indicates a lowest AC that is recommended for aggregation of MPDUs in the A-MPDU.
