The method includes receiving the DL MU PPDU, decoding a frame from the DL MU PPDU, where the frame includes an indication requesting the STA to provide a trigger-based immediate acknowledgement, determining whether trigger information for an uplink (UL) MU transmission has been obtained from the DL MU PPDU, responsive to a determination that the trigger information has been obtained from the DL MU PPDU, transmitting a trigger-based immediate acknowledgement frame to the AP during the UL MU transmission, according to the trigger information, and responsive to a determination that the trigger information has not been obtained from the DL MU PPDU, refraining from transmitting the trigger-based immediate acknowledgement frame to the AP."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"ACK policy for uplink and downlink MU PPDU","description":"A method implemented by a station (STA) in a Wireless Local Area Network (WLAN) to acknowledge a downlink (DL) multi-user (MU) physical layer (PHY) Protocol Data Unit (PPDU) transmitted by an access p","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9762487","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
