Abstract: A shared wireless fidelity (WiFi) communication device receives a first frame transmitted from a sharing access point (AP), and transmits a second frame to a non-AP station (STA). The first frame at least contains information of a shared period that is allowed to be used by the shared WiFi communication device, and the shared period is a subset of a time period of transmission opportunity (TXOP) obtained by the sharing AP. The second frame at least contains the information of the shared period.

Abstract: Techniques pertaining to dynamic link selection for reliable retransmission in wireless communications are described. A multi-link device (MLD) establishes a block acknowledgement (Block Ack) agreement or a protected Block Ack agreement with one other MLD on one or more enabled links for dynamic link selection. The MLD communicates with the other MLD on at least one of the one or more enabled links prior to termination of the Block Ack agreement or the protected Block Ack agreement.

Abstract: One wireless communication method includes: receiving a request action frame; and in response to the request action frame, generating and sending an acknowledgement (ACK) control frame that is configured to serve as a response action frame for the request action frame, wherein the response action frame is not solicited by the request action frame. Another wireless communication method includes: receiving a request action frame; and in response to the request action frame, generating and sending an acknowledgement (ACK) control frame and a time-constrained response action frame following the ACK control frame, wherein the time-constrained response action frame is solicited by the request action frame.

Abstract: A multi-link device (MLD) includes a transmit (TX) circuit, a receive (RX) circuit, and a control circuit. The control circuit controls the RX circuit to receive a first frame under an operation mode parameter with a first setting, control the TX circuit to transmit a second frame responsive to the first frame under the operation mode parameter with the first setting, and after the second frame is transmitted, controls the RX circuit to receive at least one physical layer protocol data unit (PPDU) under the operation mode parameter with a second setting, wherein the second setting is different from the first setting.

Abstract: A physical protocol data unit (PPDU) transmission method includes aligning parameters of a plurality of links for constraining the plurality of links to have same capacity for PPDU transmission, and transmitting PPDUs via the plurality of links. Highest capacity supported by one of the plurality of links is different from highest capacity supported by another of the plurality of links. Each of the PPDUs is generated and transmitted under the same parameters. Ending time instants of transmission of the PPDUs are aligned

Abstract: A method of traffic flow management with stream classification service (SCS) and associated apparatus are provided, where the wireless communications system may include a first device and a second device. The method may include: carrying and sending a first descriptor element in a first request frame, requesting for a SCS stream from the first device, wherein the first descriptor element is related to the SCS, wherein the first request frame includes a first indication, indicating whether the second device agrees that the SCS stream and any other stream from the first device to the second device share a same traffic identifier (TID).

Abstract: Various schemes pertaining to coordinated time-division multiple-access (C-TDMA) protocols, transmission opportunity (TXOP) sharing modes for time allocation, and exchange of parameters in multi-access point (multi-AP) systems are described. An apparatus (e.g., a sharing access point (AP)) acquires a TXOP. The apparatus also triggers one or more shared APs to participate in C-TDMA communications with respectively associated stations (STAs) within the TXOP.

Abstract: A wireless communication method includes: categorizing a plurality of different beacon elements into a first group of elements and a second group of elements; generating a beacon frame, which is configured to carry the first group of elements, wherein the beacon frame is compliant to at least one legacy generation of Wi-Fi technology; generating a second frame, which is configured to carry the second group of elements, wherein the second frame is compliant to a non-legacy generation of Wi-Fi technology rather than the at least one legacy generation of Wi-Fi technology; and sending the beacon frame and the second frame.
