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.

6. 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) control frame indicating at least a group of wireless transmit/receive units (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. - View Dependent Claims (7, 8, 9, 10, 21, 22)

16. 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) control frame indicating at least a group of wireless transmit/receive units (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 (17, 18, 19, 20, 23, 24)
