Abstract: Disclosed are a system and method for avoiding interference in direct communication between peers in a Wi-Fi network. A station (STA) desiring to communicate directly with another STA reports a change in interference to a function that determines a set of unsafe frequencies caused by interference near the STA. The function sends a report containing the set of unsafe frequencies to the AP for the STA. The AP then evaluates the severity of the interference and selects a set of RUs that are suitable for a TXOP for direct communication between the STA and another STA. The AP informs the STAs of the selected set of RUs, and the STAs communicate with each other using the selected RUs. If allowed, the STA sends feedback regarding the success of the communication to the AP.

Abstract: Techniques and apparatus for performing sticky client detection and/or remediation with machine learning are described. An example technique includes determining one or more parameters associated with roaming activity of a client station (STA) within a wireless network. The one or more parameters are evaluated with a machine learning model to predict a sliding boundary associated with the client STA, a first access point (AP) within the wireless network, and a second AP within the wireless network. Information associated with the sliding boundary is transmitted to the first AP. A frame including a request for the client STA to roam to the second AP and the information associated with the sliding boundary is transmitted to the client STA.

Abstract: Embodiments herein use a 5G node to provide supplemental power to an AMP STA to assist with Wi-Fi communication. Wi-Fi APs may not provide sufficient power wirelessly for the AMP STA to transmit data, or to transmit data as frequently as desired by the AMP STA. A controller can determine when an AMP STA is not receiving sufficient wireless power and provides instructions to a 5G node to provide supplemental power to the AMP STA. The AMP STA can use the power received from the 5G node to transmit Wi-Fi data to the AP.

Abstract: Embodiments herein describe BKDs that can transmit reply messages using different frequencies than the frequencies of wireless transmissions they receive which can reduce collisions in a Wi-Fi environment. In one embodiment, when transmitting power to be used by a BKD to transmit a reply message, an access point (AP) also includes an parameter that affects the frequency used by the BKD when transmitting its signal. For example, the AP can direct the BKD to use a frequency in a channel that is not used by other Wi-Fi Devices. The BKD can be equipped with a frequency filter that can shift the carrier frequency of the BKD response (compared to the carrier frequency of the energy-bearing signal) allowing the response signal to be transmitted on a different frequency than the one which was received.

Abstract: As reconfigurable Intelligent Surface devices (RISs) and ambient power devices become more common, it is advantageous to connect and leverage the capabilities of these devices into various wireless networks, including Wi-Fi networks. Configuring an RIS in a wireless network to provide and improve communications between an access point (AP) and an ambient power device is described. Configuring the RIS may include using a series of sounding frames between the AP and the ambient power device to update and control an RIS to improve transmission between the AP and the ambient power device.

Abstract: Differentiated service in a federation-based access network is provided by receiving a set of credentials from a User Equipment (UE) for a wireless network offering a plurality of service levels. In response to determining that the set of credentials indicate a realm associated with a given service level, network access is provided to the UE according to the given service level. In response to determining that the given service level is not a highest service level in the wireless network, a list of one or more preferred realms is transmitted to the UE, where each realm of the list of one or more preferred realms is associated with one or more higher service levels than the given service level.

Abstract: Techniques for improved networking are provided. An indication that a mobile device is in a first region of a physical space is received, and one or more current exogenous factors are determined for the physical space. Positioning technique accuracy is predicted for each respective positioning technique of a plurality of positioning techniques by processing the indication of the first region and the one or more current exogenous factors using a machine learning model. A first positioning technique of the plurality of positioning techniques is selected based on the predicted positioning technique accuracies.

Abstract: Techniques for dynamically negotiating a service legal agreement (SLA) between a roaming device and a visited network (VN) in an identity federation. An identity profile provided to a user device by an identity provider (IDP) is accessed by the user device. The identity profile includes a first SLA criteria. An advertisement from the VN indicating one or more SLAs supported by the VN is received at the user device. The advertisement is received before the user device has associated with the VN. The IDP and the VN are part of a same identity federation. It is determined that the SLA supported by the VN satisfies the first SLA criteria. Upon that determination, an acceptance is transmitted by the user device to the VN, and the user device is associated with the VN.
