Abstract: Apparatuses, systems, and methods for a wireless device to perform data stall mitigation. The wireless device may establish, at an HTTP layer of the wireless device, a data connection over a first network interface of the wireless device. The wireless device may compare an available duration of data in a data buffer associated with the data connection to a first threshold and notify, in response to the available duration approaching the first threshold, at least one lower layer of the wireless device of an emergency deadline. At least one lower layer may perform one or more remedial actions to avoid and/or mitigate a data stall.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for enhancement of multi-SIM devices, such as UE 106. A network may increase paging retries for known MU-SIM devices, e.g., based on an indication of capabilities from a MU-SIM device. The indication may be via a NAS registration request, an RRC capability procedure, and/or an RRC UE assistance procedure. Additionally, a network may include an indication of a paging priority to the UE. The UE may then determine a response to the page based, at least in part, on the indicated priority. Further, the UE may indicate a tune-away to the network. The indication of the tune-away may include a cause and/or duration for the tune-away and may be provided at an RRC level or a network access stratum (NAS) level.

Abstract: This disclosure relates to performing implicit radio resource control state transitions in a cellular communication system. A wireless device may establish a radio resource control (RRC) connection with a cellular base station. A data inactivity timer length and a target RRC state for implicit RRC transitions may be determined. A data inactivity timer having the determined data inactivity timer length may be initiated. It may be determined that the data inactivity timer has expired. The wireless device may transition to the target RRC state based at least in part on determining that the data inactivity timer has expired.

Abstract: Apparatuses, systems, and methods for RACH procedures to avoid excessive handover/secondary cell group failures. A base station may declare a handover and/or secondary cell group (SCG) failure and may determine that a failure threshold has been met. The base station may perform a remedial action in response to meeting the failure threshold. The failure threshold may be multi-dimensional, where a first dimension is associated with a number of handover/SCG failures and where a second dimension is associated with a time period in which the number of handover/SCG failures occurred. Further, a third dimension may be associated with a UE mobility state and a fourth dimension may be associated with whether the UE is using FR1 or FR2. The remedial action in response to meeting the failure threshold may include the base station suspending transmission of measurement object configurations for a specified period of time.

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: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) to adaptively manage system information, particularly on-demand system information. A UE may receive mandatory system information from a wireless network and may determine that at least some additional, e.g., on-demand, system information would be beneficial. The UE may evaluate whether a condition is met to request the additional system information and may initiate a random access procedure to request the additional system information. If the random access procedure fails, the UE may adjust its behavior, including reselection behavior, in response to lacking the additional system information.

Abstract: Methods and devices for creating and operating a combined network and computational slice instance (NCSI) in a Multi-access Edge Computing (MEC) scenario. Communication and computational resources may be reserved by a NCSI controller for the NCSI. The communication resources may include network slices and the computational resources may include MEC computational resources of one or more MEC servers. The reserved resources may be selected based on quality of service (QoS) requirements of UEs that will utilize the NCSI. During operation, reserved resources for the NCSI may be dynamically renegotiated based on an aggregate load of the NCSI, the QoS of data traffic, and/or updated QoS requirements of the UEs.

Abstract: Apparatuses, systems, and methods for performing authorization revocation for unmanned aerial vehicles. A cellular network element of a cellular network may receive a request to revoke authorization of a wireless device that is an element in an unmanned aerial system. The cellular network element may provide an indication to the wireless device to disconnect from any other elements of the unmanned aerial system based at least in part on the request to revoke authorization.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) and/or cellular network to avoid invalidation of a subscriber identity module (SIM). A UE may initiate a connection with the network. The network may reject the connection attempt. The UE may selectively determine whether to invalidate the SIM, network, or both. The UE may consider various factors such as details of the connection rejection message, identity of the network, its relationship to the network (e.g., whether the network is a preferred network, etc.), a number of connection rejections received, time remaining on one or more timers, availability of other networks, etc.

Abstract: Apparatuses, systems, and methods for performing efficient emergency services fallback. A cellular network element may provide emergency services fallback information to a wireless device during 3GPP 5GS cellular registration. The emergency services fallback information may include an indication of whether emergency services fallback via fallback to evolved packet core service is supported. The emergency services fallback information may also include an indication of whether emergency services fallback via fallback to circuit switched service is supported.
