Abstract: According to techniques described herein, a UE (which may be link budget limited) may be connected to a network using a first RAT. The UE may be configured to determine a first resource requirement for communication on the network using the first RAT and a second resource requirement for communication on the network using a second RAT. The UE may be further configured to trigger a re-selection to the second RAT in response to the UE determining that the second RAT is preferred over the first RAT based, at least in part, on a comparison of the first and second resource requirements.

Abstract: Techniques for a link budget limited UE to improve communications performance with cellular networks are disclosed. The UE may be associated with subscriptions to multiple carriers and may connect to a cell of a first carrier. The UE may detect that received signal strength from the cell is below a threshold and search for a new cell that may be of a different carrier. The UE may store a PLMN eSIM priority look up table and the search may be based on the look up table. Additionally, the UE may track received signal strength and geographic location in a first data structure that the UE may send to a server. The UE may receive a second data structure from the server that includes received signal strength at geographic locations compiled from a plurality of UEs, including the UE. The UE may also use the second data structure in searches for a new cell.

Abstract: Techniques, described herein, include solutions for anonymous geospatial evaluation via a wireless network. For example, a user equipment (UEs) may monitor a current location of UE for entry into a bounding box associated with a geographic area. Upon entry, the UE may generate and report an anonymous presence indicator to a bounding box server via the wireless network. The anonymous presence indicator may include information describing an instance of a UE being located within the bounding box; however, the anonymous presence indicator may not include information indicating an identifier of UE and/or a user of UE. The UE may report another anonymous presence indicator upon expiration of a re-report timer and/or upon entry into another bounding box.

Abstract: Embodiments herein provide apparatuses and techniques for providing a notification indicating guidance to reaching cellular connectivity in the event of a loss of cellular connectivity and for guiding a user of a user equipment to a location with cellular connectivity. The notification may be generated based on expiration of a timer, a screen unlock operation, or an application connection failure. The notification may indicate how long ago the cellular connectivity loss occurred and how far away a nearest location is with a cellular connectivity was. The user equipment may display a map interface based on user input selecting the notification. The map interface may show a map of the current location of the user equipment, a nearest location with cellular connectivity to the user equipment, and a path, which includes a tracked path of user equipment and a proposed path to the nearest location with cellular connectivity.
