  • Publication number: 20240137748
    Abstract: A wireless communication network receives a first Subscriber Identity Module (SIM) profile from a User Equipment (UE) and authenticates the UE based on the first SIM profile. The network receives a first slice request from the UE and authorizes a first wireless network slice for the UE based on the authentication of the first SIM profile and the first slice request. The network receives a second SIM profile from the UE and authenticates the UE based on the second SIM profile. The network receives a second slice request from the UE and authorizes a second wireless network slice for the UE based on the authentication of the second SIM profile and the second slice request. The network wirelessly exchanges first slice data with the UE over the first wireless network slice, and simultaneously, exchanges second slice data with the UE over the second wireless network slice.

  • Publication number: 20240098527
    Abstract: This document describes improvements in range and reliability for wireless mesh networks implementing IEEE 802.11 networking technologies. Reducing the number of spatial streams, N, to a lower value at middle and far distance ranges using an optimized rate control algorithm, preemptively trades off a lower throughput limit for a higher link budget. This higher link budget provides longer range and higher RF link reliability by using an N×N spatial diversity of MIMO RF channels for maximizing link budget instead of network throughput.

    Abstract: Aspects herein provide a system, media, and methods for a mobile edge computer that renders extended reality (XR) in support of a local user device, via a local network. The mobile edge computer can continue to provide updated XR renderings in near real-time when user position data remains within a particular viewing angle, without requesting updated content or rendering assistance from a remote application. When user position data is determined to be outside of the viewing angle, then the mobile edge computer may request additional content from the remote application.
