  • TID-Based UL Trigger In Wireless Communications
    Publication number: 20240251402
    Abstract: Techniques pertaining to traffic identifier (TID)-based uplink (UL) trigger in wireless communications are described. An apparatus (e.g., an access point (AP)) transmits a TID-based trigger frame to one or more stations (STAs). The apparatus then receives a trigger-based (TB) UL transmission from at least a first STA of the one or more STAs responsive to transmitting the TID-based trigger frame. In receiving the TB UL transmission, the apparatus receives a first type of traffic corresponding to a first TID indicated by first TID information that is associated with the first STA and included in the TID-based trigger frame.

  • Apparatuses and methods for fast switching from trigger mode to contention mode uplink (UL) transmission
    Patent number: 11552727
    Abstract: A wireless communication terminal including a wireless transceiver and a controller is provided. The wireless transceiver performs wireless transmission and reception to and from an Access Point (AP). The controller is coupled to the wireless transceiver, and configures the wireless communication terminal to operate as a Station (STA) to associate with the AP in compliance with an Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard. Also, the controller receives a beacon frame indicating to disable an UL MU operation from the AP via the wireless transceiver, and enables the STA to operate in a contention mode for UL transmission in response to receiving the beacon frame indicating to disable the UL MU operation.
