1. A method for aggregating short packet transmissions in a multi-user (MU) wireless local area network (WLAN) system performed by an access point (AP), the method comprising:
- sending a downlink (DL) data frame containing control information, wherein the control information includes uplink (UL) MU response scheduling information for a group of wireless transmit/receive units (WTRUs);
sending a DL control frame indicating at least the group of WTRUs for simultaneous transmission of acknowledgments (ACKs) or block ACKs (BAs); and
simultaneously receiving ACKs or BAs from the group of WTRUs over a plurality of respective sub-channels or resource units.

Abstract
Mechanisms may be used for aggregating acknowledgement (ACK), block ACK (BA) and/or short packets transmissions for multi-user (MU) wireless communication systems. Aggregation mechanisms may be used for uplink (UL) and/or downlink (DL) orthogonal frequency division multiple access (OFDMA), and/or UL/DL multiple-user multiple input multiple output (MU-MIMO) transmissions, for example. Multi-user short packets may be aggregated and/or simultaneously transmitted for DL, UL, or peer-to-peer (P2P) transmissions.

8. An access point (AP) configured to aggregate short packet transmissions in a multi-user (MU) wireless local area network (WLAN) system, the AP comprising:
-
a transmitter configured to send a downlink (DL) data frame containing control information, wherein the control information includes uplink (UL) MU response scheduling information for a group of wireless transmit/receive units (WTRUs); the transmitter configured to send a DL control frame indicating at least the group of WTRUs for simultaneous transmission of acknowledgments (ACKs) or block ACKs (BAs); and a receiver configured to simultaneously receive ACKs or BAs from the group of WTRUs over a plurality of respective sub-channels or resource units. - View Dependent Claims (9, 10, 11, 12, 13, 14)
