Abstract: Embodiments for virtual reality (VR) and augmented reality (AR) scenes updates at VR/AR devices in a network are described. Network traffic for the scene updates is divided into traffic layers such as coarse grain (CG) layer traffic and a fine grain (FG) layer traffic for a give VR/AR scene update. The CG layer traffic is scheduled first in resource units (RUs) of a plurality a transmission opportunity (TXOP) for a VR device and FG layer traffic is scheduled in remaining RUs during the TXOP to provide synchronous viewing experiences to users of the VR/AR devices.

Abstract: Techniques for wireless communications are disclosed. These techniques include identifying a change in at least one of: (i) a WiFi radio channel or (ii) a cellular radio channel for a wireless station (STA) supporting both WiFi and cellular radio access technologies. The techniques further include determining one or more WiFi radio channels subject to interference from the cellular radio for the STA, based on a network message received from the STA, and modifying one or more parameters for WiFi communication relating to the STA, based on the determined one or more WiFi radio channels subject to interference.

Abstract: A method includes receiving a first buffer status report from a WiFi access point and receiving a second buffer status report from a first NR-U radio unit. The method also includes scheduling, based at least in part on the first buffer status report and the second buffer status report, both the WiFi access point and the first NR-U radio unit to transmit during a first time slot using a channel. The WiFi access point transmits using a first sub-channel of the channel, and the first NR-U radio unit transmits using a second sub-channel of the channel different from the first sub-channel.

Abstract: A device includes a memory and a hardware processor communicatively coupled to the memory. The hardware processor determines that a computing device communicatively coupled to an access point performed an action with respect to the access point and in response to determining that the action causes a deviation from a multi-user uplink policy of the access point, transmits a disciplinary message to the computing device.

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.

Abstract: Differentiated service in a federation-based access network is provided by receiving, with a request for access to a wireless network offering at least a two different service levels based on user identities, a set of user credentials from a User Equipment (UE); forwarding, for authentication, the set of user credentials to an identity provider in an identity federation with the wireless network, wherein the identity provider is independent from the wireless network; in response to determining that the set of user credentials indicate a realm known to be associated with a given service level, providing network access to the UE according to the given service level; and in response to determining that the given service level is not a highest service level in the wireless network, transmitting a list of preferred realms to the UE that are associated with higher service levels than the given service level.

Abstract: Handoff assistance across multiple radio access technologies can be provided by identifying a first Qualitative Level of Service (QLoS) of a first network that a User Equipment (UE) is connected to for data transmission; identifying a second QLoS of a second network that the UE is not connected to for data transmission; and in response to determining that a difference between the first QLoS and the second QLoS satisfies a handoff threshold, requesting a first access point in the first network to initiate handoff of the UE to a second access point in the second network or recommending from the first access point to the UE to request such a handoff, wherein handoff disconnects the UE from the first network for data transmission and connects the UE to the second network for data transmission.
