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.

Abstract: A station (STA) for communicating with an Access Point (AP) in a wireless communication system is provided. The STA includes a wireless transceiver and a processor. The wireless transceiver performs wireless transmission and reception to and from the AP. The processor receives allocation information indicating a first user block for the STA in a first RU of an MU-PPDU from the AP via the wireless transceiver, and the first RU includes multiple user blocks allocated for different STAs. Also, the processor sends Uplink (UL) data or receives Downlink (DL) data in the first user block to or from the AP via the wireless transceiver according to the allocation information.

Abstract: A multi-link operation (MLO) Wi-Fi dual traffic identification data transmission method is adopted for an MLO Wi-Fi access point (AP) and an MLO Wi-Fi client. The method includes linking the MLO Wi-Fi client to the MLO Wi-Fi access point (AP) with a first link and a second link, rendering traffic in the first link a first block acknowledgement (BA) window with a first traffic identification (TID), rendering traffic in the second link a second block acknowledgement (BA) window with a second traffic identification (TID), using the first block acknowledgement (BA) window with the first TID to transmit data through the first link, and using the second block acknowledgement (BA) window with the second TID to transmit data through the second link.

Abstract: Techniques pertaining to adaptive transmission opportunity (TXOP) sharing for latency-sensitive traffic in wireless communications are described. An apparatus determines whether to activate an adaptive TXOP sharing mechanism with respect to a plurality of traffics having different latency requirements and pending transmission. In response to a positive determination, the apparatus utilizes the adaptive TXOP sharing mechanism in transmitting one or more traffics of the plurality of traffics associated with a plurality of stations (STAs) by performing either or both of: (i) selecting a candidate traffic from the one or more traffics of the plurality of traffics; and (ii) adjusting a transmission time of the candidate traffic in transmitting the candidate traffic during a TXOP.
