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 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).

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. None of the first frame and the second frame carries indication of operation mode parameter change that specifies the use of the second setting, and the use of the second setting is indicated by transmission of the second frame.

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: Methods and apparatus for performing secure ranging measurements between wireless devices are disclosed herein according to embodiments of the present invention. The described embodiments use key values to indicate which LTF sequence (e.g., LTF measurement exchange) to use for performing wireless ranging measurements. A LTF sequence that is received by a wireless device that does not correspond with the associated key value is determined to be invalid. Invalid LTF sequences may be disregarded as signal noise.

Abstract: A capability allocation method employed by a wireless fidelity (Wi-Fi) device includes: during association between the Wi-Fi device and another Wi-Fi device, setting up a first capability allocation of a first non-AP station (STA); and after the first non-AP STA associates with a first AP, changing the first capability allocation of the first non-AP STA in the absence of re-association. Each of the Wi-Fi device and the another Wi-Fi device includes a plurality of stations. The first AP is affiliated to the another Wi-Fi device. The first non-AP STA is affiliated to the Wi-Fi device.
