Abstract:
A method and apparatus for multi-user concurrent random access for wireless local area networks (WLANs) is described. The method, implemented in a wireless transmit/receive unit (WTRU), includes detecting a trigger frame for uplink (UL) multi-user (MU) transmission. The trigger frame includes an assignment of resource units (RUs) for random access in upcoming UL MU packet data convergence protocol (PDCP) protocol data units (PPDUs) and an indication that the trigger frame is one of a plurality of trigger frames in a cascading sequence of trigger frames in an MU transmission opportunity (TxOP). The method further includes selecting one of the RUs in the assignment of RUs for a random access transmission and sending the random access transmission on the selected one of the RUs.

Claim (Index 15):
An access point (AP) comprising:\n a processor and a transmitter, the processor and the transmitter being configured to generate and transmit a trigger frame for uplink (UL) multi-user (MU) transmission to a plurality of stations (STAs), the trigger frame including an assignment of resource units (RUs) for random access in upcoming UL trigger-based physical layer protocol data units (PPDUs) and an indication that the trigger frame is one of a plurality of trigger frames in a cascading sequence of trigger frames in an MU transmission opportunity (TxOP); and a receiver, the receiver and the processor being configured to receive the UL trigger-based PPDUs, the received trigger-based PPDUs including at least one frame from at least one of the plurality of STAs on one of the assigned RUs, wherein the transmitter and the processor are further configured to transmit an acknowledgement for the at least one frame, the acknowledgement being aggregated with one of the plurality of trigger frames in the sequence.
