Abstract: A physical protocol data unit (PPDU) transmission method includes: setting parameters of each of a plurality of links for enabling the plurality of links to have different capacity for PPDU transmission, wherein parameters of one link are different from parameters of another link, and highest capacity supported by the one link is higher than highest capacity supported by the another link; aligning an ending time instant of transmission of a first PPDU transmitted via the one link with an ending time instant of transmission of a second PPDU transmitted via the another link through setting a content that is carried by the first PPDU transmitted via the one link; and transmitting PPDUs via the plurality of links, wherein one PPDU is transmitted via each of the plurality of links, and the PPDUs include the first PPDU and the second PPDU.

Abstract: A Wi-Fi communication method includes: performing resource allocation for multi-user transmission orthogonal frequency division multiple access (OFDMA) according to a regulated frequency band boundary and a resource unit (RU) type, and sending information indicative of the resource allocation, where the RU type includes at least one of regular RU (rRU) and distributed-tone RU (dRU), the resource allocation indicates RUs or multiple RUs (MRUs) allocated in a channel, the channel is across the regulated frequency band boundary, and an RU or MRU allocated per user in the channel is not across the regulated frequency band boundary when using rRU.

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.

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: Embodiments of the present invention provide a method and apparatus for simultaneous transmission and reception of data wirelessly using different wireless bands. The multi-link operations described herein can provide higher network throughput and improved network flexibility compared to traditional techniques to wireless communication. Link management operations such as enabling and disabling of a link may be performed by an AP or STA by sending a frame over a link that is currently active. Moreover, an AP may request a switch to a different link available on the AP side for MLO, for example, when a link is occupied by interference and is not available when AP needs to use the link, and the operating parameters of a target link can be updated.
