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: An access point (AP) includes a transmitter (TX) circuit, a receiver (RX) circuit, and a control circuit. The control circuit negotiates with at least one another AP via the TX circuit and the RX circuit, for setting up a coordinated service period (SP). In addition, a method for setting up the coordinated SP in a multiple AP environment includes: sending a request frame from a first AP to at least one second AP, wherein the request frame includes a plurality of SP parameters; receiving a response frame generated from the at least one second AP in response to the request frame; and in response to the response frame, setting up the coordinated SP by sending a setup frame to the at least one another AP, wherein the setup frame is set by updating at least a portion of the plurality of SP parameters.

Abstract: During association between an access point (AP) multi-link device (MLD) and a non-AP MLD, the non-AP MLD indicates a first capability allocation of a first combination of affiliated stations for a first combination of enabled links on the non-AP MLD, and indicates a second capability allocation of a second combination of affiliated stations for a second combination of enabled links on the non-AP MLD. For example, the first combination of affiliated stations and the second combination of affiliated stations have different numbers of stations in the non-AP MLD, and the first combination of enabled links and the second combination of enabled links have different numbers of enabled links. Hence, during the association between the non-AP MLD and the AP MLD, capabilities of different non-AP station combinations corresponding to different enabled link combinations supported by the non-AP MLD are signaled to the AP MLD.

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: Various techniques and schemes pertaining to extremely-high throughput (EHT) multi-link maximum channel switching in wireless communications are described. A station (STA) multi-link device (MLD) receives an indication from a reporting access point (AP) affiliated with an AP MLD on one link of multiple links. The STA MLD determines a channel switching time when a reported AP switches from operating in a current channel of the reported AP to operating in a new channel on one other link of the multiple links based on the indication.

Abstract: Various techniques and schemes pertaining to ultra-high reliability (UHR) multi-link direct link operation in wireless communications are described. A first non-access point (non-AP) multi-link device (MLD) establishes multiple links as multi-link direct links with a second non-AP MLD. The first non-AP MLD also maintains a multi-link association with an AP MLD. The first non-AP MLD communicates with the second non-AP MLD over one or more links of the multiple links in a multi-link direct link operation.
