Abstract: Aspects of the disclosure provide control-plane signaling to support a user equipment (UE)-assisted local caching feature, where information content may be locally cached at or near a base station in a wireless communication network. The control plane signaling may include a system information broadcast (SIB) to advertise availability of the feature; a UE capability message that indicates UE support of the feature; and/or radio resource control (RRC) configuration signaling to configure the UE to utilize the feature. Further aspects describe operation and maintenance (OAM) configuration of a base station to utilize the feature. A base station may additionally check for UE eligibility to utilize the feature, e.g., based on the user's subscription. In further examples, various enhancements to the user-plane signaling to utilize the UE-assisted local caching feature are provided. Other aspects, embodiments, and features are also claimed and described.

Abstract: Methods and devices for dynamic VSIM provisioning on a multi-SIM wireless device having a first SIM as a Universal Integrated Circuit Card (UICC) and a virtual SIM (VSIM). A provisioning server may receive updated information from the wireless device, and based at least partially on the received information, determine whether the SIM profile on the VSIM of the wireless device should be changed. To change the SIM profile, the provisioning server may determine whether remote credential management procedures are enabled. If so, the provisioning server may select a new SIM profile from a plurality of SIM profiles, and provision the new SIM profile in the VSIM using remote credential management procedures. If remote credential management procedures are unavailable, the provisioning server may select a remote SIM from a plurality of remote SIMs associated with the provisioning server, and run the remote SIM to execute authentication processes for the wireless device.

Abstract: Methods, systems, and devices for wireless communications are described. An access and mobility management function (AMF) may register a configuration of one or more RAN entities to a network repository function (NRF). The AMF may register information associated with a device with a UDM. A network data analytics function (NWDAF) may perform RAN discovery via the NRF, the UDM, or both. The NWDAF may receive an analytics request from a device, and the NWDAF may query the NRF, the UDM, or both for information about one or more targets of the analytics request, and the NWDAF may receive such information from the NRF, the UDM, or both. The NWDAF may transmit a data collection request to the RAN and the NWDAF may receive data back from the RAN.

Abstract: Aspects presented herein may enable a network entity (e.g., a consumer network entity) to request data and/or analytics (e.g., AI/ML analytics, AI/ML inference, etc.) from another network entity (e.g., a RAN) via a core network or a function associated with the network (e.g., an NWDAF of the core network). In one aspect, a core network entity receives, from a first network entity, an analytics request. The core network entity transmits, to a second network entity, a data collection request based at least in part on the analytics request. The core network entity receives, from the second network entity, a data collection response based on the data collection request. The core network entity transmits, to the first network entity, an analytics response based at least in part on the data collection response.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may initiate a quality of experience (QoE) session for a QE configuration at an application layer of the UE. The UE may provide, from the application to a radio resource control (RRC) layer of the UE, a session start or stop indication based at least in part on initiating the QoE session. The indication may include at least one of a service type, an RRC level identifier, a QoE reference, or a QoE measurement collection. The UE may provide, to a base station and based at least in part on the indication, information indicating the service type, the RRC level identifier, the QoE reference, or the QoE measurement collection. Numerous other aspects are described.
