Abstract: A wireless communication method employed by an access point (AP) includes: negotiating with another AP for setting up a coordinated service period (SP), and sending a first announcement frame inside a first basic service set (BSS) to inform that the coordinated SP has been created. The step of negotiating with the another AP for setting up the coordinated SP includes: receiving a request frame from the another AP, wherein the request frame includes a plurality of SP parameters; and sending a response frame to the another AP. The AP belongs to the first BSS, and the another AP belongs to a second BSS different from the first BSS.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be an access point (AP) multi-link device (MLD). In certain configurations, the AP MLD establishes a primary link on a first channel and a non-primary link on a second channel. The AP MLD determines to perform a channel switch operation to switch a first link of the primary link and the non-primary link to operating on a different channel. The AP MLD transmits, on the primary link and prior to the switching of the first link, a first management frame including a first element indicating a target switching time for the switching of the first link. The AP MLD transmits, on the primary link after the switching of the first link, a second management frame indicating that an AP on the first link is in operation.

Abstract: Various techniques and schemes pertaining to primary link identification schemes in wireless communications are described. An access point (AP) multi-link device (MLD) establishes a plurality of links, the plurality of links comprising a primary link and a non-primary link that constitute a non-simultaneous-transmission-and-reception (NSTR) link pair. An AP affiliated with the AP transmits a beacon frame with an indication on whether or not the AP or a reported AP is affiliated with an NSTR AP MLD and is operating on the primary link of the NSTR link pair.

Abstract: Techniques pertaining to transmission protection with static puncturing in wireless communications are described. An apparatus (e.g., a station (STA)) receives a control frame with bandwidth signaling that is transmitted in a channel width of the control frame including one or more non-punctured non-primary subchannels within the channel width. The apparatus then determines the one or more non-punctured non-primary subchannels within the channel width of the control frame and also determines whether to transmit a response control frame responsive to receiving the control frame. Depending on a result of the determining, the apparatus either refrains from transmission of the response control frame or transmits the response control frame in at least one subchannel within the channel width of the control frame.

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: 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: Various techniques and schemes pertaining to extremely-high throughput (EHT) enhanced multi-link single-radio (EMLSR) target wake time (TWT) operation in wireless communications are described. A non-access point (non-AP) multi-link device (MLD) enables an enhanced multi-link single-radio (EMLSR) mode. The non-AP MLD also establishes one or more TWT agreements with an access point (AP) MLD on a first link and a second link of multiple links such that data exchange between a first station (STA) affiliated with the non-AP MLD and a first AP affiliated with the AP MLD occurs on the first link during a TWT service period (SP) while an EMLSR mode operation is performed on the second link.

Abstract: A first multi-link device (MLD) enables an enhanced multi-link single-radio (EMLSR) mode or an enhanced multi-link multi-radio (EMLMR) mode. A first station (STA) affiliated with the first MLD receives from a second MLD and in a first operating channel of the first STA an initial control frame indicating an allocated resource unit (RU), which is indicated in a Secondary RU Allocation subfield in the initial control frame. A second STA affiliated with the first MLD switches from a second operating channel of the second STA to an allocated channel in which the allocated RU is located. The second STA then receives information from the second MLD on the allocated RU during a transmission opportunity (TXOP).
