1. A method of operation in a wireless communication network in which one physical access point (AP) implements a plurality of virtual APs corresponding to a plurality of respective basic service sets (BSSs), comprising:
receiving, at a first client station, a management frame from the physical AP, the management frame including an indication of a plurality of respective BSS identifiers (BSSIDs) of the plurality of BSSs that correspond to the plurality of virtual APs;
receiving, at the first client station, an indication from the physical AP of a single BSS color identifier (ID) that corresponds to all of the virtual APs in the plurality of virtual APs;
associating, by the client station, with a first virtual AP among the plurality of virtual APs; and
transmitting, by the first client station, a first signal as part of an uplink (UL) multi-user transmission to the physical AP, the first signal having i) a first physical layer (PHY) preamble with a field set to the single BSS color ID, and ii) a PHY payload with data intended for the first virtual AP, wherein the first signal is transmitted while one or more second client stations transmit one or more second signals with data intended for one or more second virtual APs among the plurality of virtual APs as part of the UL multi-user transmission to the physical AP.
