Abstract: A user equipment (UE) supports communication over a first (lower) frequency range and a second (higher) frequency range. The UE determines an extent of preference of the second frequency range over the first frequency range, e.g., based on one or more of the following: sensor measurements; physical channel measurements; battery conditions; weather conditions; voice call activity; indoor/outdoor/in-car status; learned relationships between previous location-time conditions and performance on the second frequency range; etc. The UE device may control search activity and/or measurement activity on the second frequency range based on the preference extent, e.g., by controlling rates of repetition of search and/or measurement on the second frequency range, or by adding a measurement bias to a measurement reporting threshold, or by adding a delay to a measurement reporting time for a measurement, or by disabling search and measurement on the second frequency range.

Abstract: This disclosure relates to techniques for a wireless device to perform low latency communication using historical beam information. The wireless device may establish a radio resource control connection, and may subsequently release the resource control connection. The wireless device may store antenna element and beam information for the resource control connection. The wireless device may determine whether to use the stored antenna element and beam information when establishing another radio resource control connection. If the wireless device determines to do so, the wireless device may use the stored antenna element and beam information when establishing that radio resource control connection.

Abstract: Embodiments described herein relate to wireless communications, including methods and apparatus for dynamically selecting subscriber identity module (SIM) profiles, electronic SIM (eSIM) profiles, multi-SIM operating modes, and/or wireless access networks for network slice based applications of wireless devices. A wireless device can include at least two SIM/eSIM profiles and switch use of SIM/eSIM profiles, change between dual SIM operating modes, and/or select a registration mode based on requirements of one or more applications in use and availability of network slices via different wireless networks.

Abstract: Several techniques using a network slice quota (NSQ) management function provide dynamic adjustment in order to meet the limitation of data rate per network slice in the uplink and downlink wireless connections in a wireless network. In one technique, when the limit is reached, the session aggregated maximum bit rates (AMBR) per subscription level is adjusted in proportionate ratio of the maximum bit rate per subscription level per user equipment (UE). In another technique, when the limit is reached, there is a proportionate equivalent increment and decrement of session AMBR based on usage patterns of the subscription levels. In a further technique, when the limit is reached, there is a proportionate equivalent increment and decrement of slice resources based on usage patterns. In yet another technique, a quota update is attempted using the Unified Data Repository (UDR).

Abstract: Computer systems and methods are described for operating a network data and analytics function (NWDAF) in a cellular core network. The NWDAF receives user equipment (UE) mobility information from a first network function of the cellular network system and receives edge application server (EAS) information from a second network function of the cellular network system. The NWDAF derives data analytics based at least in part on the UE mobility information and the edge application server information. The NWDAF receives a request for the data analytics from a third network function in the cellular network system, and provides the data analytics to the third network function.

Abstract: Systems and methods are provided to improve candidate search and measurement in non-standalone (NSA) and standalone (SA) 5G new radio (NR) multi-radio access technology (RAT) environments. For Evolved Universal Terrestrial Radio Access Network (E-UTRAN) NR-dual connectivity (EN-DC), a user equipment (UE) skips 5G band measurements for an initial search or an out-of-service (OOS) search. For SA dual connectivity, the UE avoids 5G remaining band (RBS) scans and limits 5G deviated band search (DBS) scans to bands configured for the carrier.

Abstract: Emergency services support is indicated to roaming devices in a wireless network. A user equipment (UE) may receive a message from the wireless network indicating at least one public land mobile network (PLMN) that provides emergency services support for devices in limited service. The UE may store, in a non-volatile memory (NVM), an identifier of the at least one PLMN in a whitelist of limited service emergency services support. In response to a trigger in a roaming limited service condition of the UE, the UE may establish an emergency session with a selected PLMN based on the whitelist of limited service emergency services support.

Abstract: A user equipment (UE) is configured to connect to a next generation nodeB (gNB) and further UE. The UE determines that a triggering event has occurred, wherein the triggering event is based on a set of proximity services (ProSe) path selection and switching (PSS) policies, transmits a setup or update request to a direct discovery name management function (DDNMF) of a 5G core network, receives UE-specific policies based on the set of ProSe PSS policies, and switches from one of a PC5 interface or a Uu interface to another one of the PC5 interface or the Uu interface.
