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.
