Each backoff counter may be associated with a respective access function. A first access function may be associated with downlink transmission of data of a first access category. A second access function may be associated with downlink transmission of a trigger frame for facilitating uplink multi-user transmission. The AP may transmit at least one of a first downlink frame or a trigger frame based at least on the decremented backoff timer associated with the first and second access functions. A station may receive the first downlink frame or the trigger frame. If the trigger frame is received, the station may transmit a second frame to the AP based on an indication of an access category contained in the trigger frame. Other methods, apparatus, and computer-readable media are also disclosed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Channel access for multi-user communication","description":"In wireless communications, an access point may decrement multiple backoff counters.
