Abstract: Payload transmission of multiple stations on a single resource unit may be performed. New and/or updated signaling may be introduced to enable a transmitter, e.g., an access point (AP), to include information/signaling in the preamble or in other frames. A receiver (e.g., a wireless station) that receives this information/signaling may accordingly determine in which RU it should decode to receive its allocated data or payload, allowing multiple receivers or STAs to share a single resource unit (RU). The new/updated signaling may include modified hybrid downlink multiuser signaling in Ultra High Reliability Signal (UHR-SIG), a group association identifier (gAID), a predefined special AID corresponding to an RU with use of a Bloom filter, multiple predefined special AIDs each corresponding to a non-overlapping group of wireless stations, and/or signaling announcing time sharing of single RUs.
