  • Patent number: 12004216
    Abstract: Embodiments of the present invention prevent interference caused by the simultaneous transmission and reception of data in a constrained multi-link operation of a wireless network. According to one embodiment, a frame from a first affiliated AP of a multi-band wireless AP is transmitted for receipt by an STA, and a second affiliated wireless AP of the multi-band wireless AP is scheduled to transmit a trigger frame to the wireless STA over a second wireless link. Accordingly, the trigger frame is transmitted from the second affiliated wireless AP to the wireless STA over the second wireless link, and the response frame solicited by the frame is scheduled for transmission after the predetermined value has expired following an end of the PPDUs containing the trigger frame.

  • Patent number: 12004191
    Abstract: Embodiments of the present invention provide a method and apparatus for coordinated multi-AP channel access in a wireless network. A wireless AP that obtains a transmission opportunity (TXOP) (a “coordinator AP”) can grant one or more STAs or APs under control of the coordinator AP the use of some of the bandwidth granted by the TXOP. The STAs or APs that are granted the use of the bandwidth are referred to as “coordinated APs.” Thereafter, a coordinator AP or a coordinated AP can create a new basic service set (BSS) of devices for coordinating data transmissions. For example, the coordinated AP may serve as a relay, where the coordinated AP services devices in a new BSS by sending and receiving data with a coordinator AP in a different BSS.

  • Patent number: 11997523
    Abstract: Various examples pertaining to efficient trigger-based (TB) multi-user (MU) uplink (UL) transmissions in wireless local area networks (WLANs) are described. A stations (STA) receives a trigger frame from an access point (AP), with the trigger frame assigning one or more resource units (RUs) corresponding to one or more subchannels of a plurality of subchannels. The STA then performs a transmission using the assigned one or more RUs responsive to receiving the trigger frame. In an event that at least one subchannel of the plurality of subchannels is detected as being busy, the one or more subchannels may include a subset (e.g., some but not all) of the plurality of subchannels.

  • Patent number: 11963100
    Abstract: Power management operations are performed by devices communicating using multiple bands simultaneously where a first wireless band can be used to send and receive power management control frames for use on a second wireless band of a wireless network. In this way, a device that is in a sleep or dose power management state on a first band can be instructed to enter an awake power management state on the first band based on a communication received over a second band that is currently active and receiving data. Embodiments of the present invention enable power to be conserved when a band is not currently being used, or when there is no more data available (buffered) for a specific band.

  • Publication number: 20240073773
    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.

  • Patent number: 11917551
    Abstract: Embodiments of the present invention are drawn to methods and electronic devices capable of performing coordinate spatial reuse for wirelessly transmitting data on a channel in coordination with another wireless AP operating an overlapping BSS using the same wireless channel. The device can perform RSSI measurements and generate Per-RU RSSI reports including the RSSI measurements information for transmission to another wireless AP. The RSSI measurement can be performed by the device based on power levels detected when receiving TB PPDUs transmitted by wireless STAs responsive to trigger frames, for example. Based on the Per-RU RSSI report, a wireless AP can be configured to transmit data to an associated wireless STA without causing significant interference when another AP of the overlapping BSS is also transmitting, and can schedule frames for transmission from associated wireless STAs accordingly.
