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: 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: 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: Various techniques and schemes pertaining to extremely-high throughput (EHT) ultra-high reliability (UHR) dynamic multi-link switching in wireless communications are described. A first access point (AP) affiliated with a first AP multi-link device (MLD) switches from operating on a first link to operating on a second link in a multi-link operation responsive to detecting the first link as busy. Then, the first AP transmits data to a first station (STA) affiliated with a first STA MLD during a transmission opportunity (TXOP) on the second link. The AP switches back to operating on the first link upon expiry of a period during which the first link is busy.

Abstract: An uplink (UL) latency indication method includes: collecting, by an access point (AP), latency information associated with communications with at least one non-AP station (STA), without asking latency measurement on said at least one non-AP STA; and performing statistical analysis on the latency information to generate at least one UL latency indicator.

Abstract: A control link switch method is employed by a wireless fidelity (WI-FI) multi-link device (MLD). The control link switch method includes: sending a request frame to another WI-FI MLD for requesting a switch process of switching a current control link to a new control link, and receiving a response frame from another WI-FI MLD. After the response frame is received, the new control link is selectively enabled at the WI-FI MLD.

Abstract: A capability indication method employed by a wireless fidelity (Wi-Fi) multi-link device (MLD) includes: during an association process between the Wi-Fi MLD and another Wi-Fi MLD, indicating a first capability allocation of a first combination of affiliated stations in the Wi-Fi MLD for a first combination of enabled links on the Wi-Fi MLD, and indicating a second capability allocation of a second combination of affiliated stations in the Wi-Fi MLD for a second combination of enabled links on the Wi-Fi MLD, wherein the first combination of affiliated stations is different from the second combination of affiliated stations, and the first combination of enabled links is different from the second combination of enabled links.

Abstract: A traffic indication signaling method includes: setting a control information subfield in an aggregated control (A-Control) subfield by traffic indication information, wherein the traffic indication information contains timing information of uplink (UL) traffic; and transmitting a frame that includes the A-Control subfield to an access point (AP). For example, the UL traffic is required by a latency sensitive traffic application.

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.
