Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) and/or cellular network to perform to perform capability updates. Under at least some circumstances, the UE may use a non-cellular (e.g., non-3GPP) access to transmit updated capability information to a cellular network. Elements of the core of the cellular network may provide an identifier corresponding to the updated capability information to the UE for use in future registrations with the cellular network. Further, the core network may provide the updated capability information to a cellular radio access network associated the cellular network. The UE and the cellular network may communicate according to the updated capability.

Abstract: Embodiments described herein relate to managing access to 5G cellular baseband resources for 5G-capable wireless devices. A wireless device can monitor application workloads by analyzing communication network performance requirements for a given application in-use or launching for future use along with system-level indications of overall device usage, battery level, and mobility status to determine whether access to 5G cellular baseband resources is recommended for an application. A 5G cellular baseband resource recommendation is provided for an application indicating a level of bandwidth in current use or expected for future use as well as a confidence metric in the bandwidth level indication. The 5G cellular baseband resource recommendation is used with additional device criteria to determine whether access to one or more 5G radio frequency bands is allowed.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for EPS fallback when initiating a voice call while camped on a 5G cell. The UE may camp on a 5G network by performing an IMS registration procedure/IMS SIP invite procedure with an IMS. The UE may initiate a voice call and determine that the voice call cannot be established over the 5G NR network. In response, the UE may perform a TAU procedure or an attachment procedure with a cell of a 4G network. The IMS may be transferred to the 4G network during TAU/attachment procedure. The UE may, in response to determining that it is barred from the 4G network, transition back to the 5G network and transmit, to the 5G NR network, a SIP cancel request to allow a context associated with the UE to be cleared from the IMS.

Abstract: This disclosure relates to methods and devices for mitigating overheating in a user equipment device (UE). The UE is configured to communicate over each of LTE and 5G NR and may be configured to communicate through 5G NR over each of a Sub-6 GHz and a millimeter Wave (mmW) frequency band. The UE is configured to establish an ENDC connection with an enB and one or more gNBs. The UE implements intelligent transmission modification and cell measurement adjustments to mitigate overheating and reduce battery drain.

Abstract: Systems, methods, and apparatuses disclosed herein can compensate for imbalances between multiple transport streams of an uplink (UL)-multiple-input and multiple-output (MIMO) transmission. These systems, methods, and apparatuses can adjust one or more signal metrics of multiple recovered transport streams of the UL-MIMO transmission that are received in the presence of imbalances between the multiple transport streams of the UL-MIMO transmission. As an example, these systems, methods, and apparatuses can inject noise into one or more of the multiple recovered transport streams to adjust the one or more signal metrics of the multiple recovered transmission streams to lessen the imbalances between the multiple transmission streams.

Abstract: A user equipment (UE) may initiate an application on a user equipment (UE) which utilizes a network slice via a packet data network (PDN) connection with a first cellular network. The first cellular network may support network slicing and voice over new radio (VONR) and one or more cells of the first cellular network may support evolved packet system (EPS) fallback procedures. The UE may receive or initiate a voice call with another UE and adjust one or more capabilities of the UE such that an EPS fallback procedure is deemphasized. The UE may receive signaling from the first cellular network to establish, based at least in part on the one or more adjusted capabilities of the UE, the voice call as a VoNR call via the first cellular network and the network slice may be maintained during the VoNR call.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE), manufacturer server, and/or cellular network to perform radio capability signaling. A new type of UE radio capability identifier is provided which may allow a network to distinguish between similar UEs that have or have not implemented a capability update. In order to perform a forced capability update, a manufacturer may issue information about the update to a cellular network (and receive acknowledgement of the information) prior to pushing the update to UEs. In response to an unforced capability update, a cellular network may maintain multiple UE radio capability identifiers for similar UEs which have or have not implemented the update. A UE radio capability identifier may be adjusted dynamically in response to temporary changes in the UE's capability.

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: A user equipment (UE) may be configured to reattempt to establish a multiple access (MA) protocol data unit (PDU) session when the UE moves to a new registration area. The UE transmits a request for a MA PDU session to the network, receives a message from the network indicating the request has been rejected, wherein the message further includes a status indication for reattempt requests to establish the MA PDU session, determines, when the UE moves into a new registration area of a PLMN, whether reattempt requests are allowed based on, at least, the status indication and transmits, when reattempt requests are allowed, a further request to establish the MA PDU session.

Abstract: Embodiments described herein relate to dynamic selection of radio access technologies (RATs) available for use by 5G wireless devices. Managing selection of RATs to use by a 5G (and 4G LTE) capable wireless device can improve performance, e.g., when an application requires a higher throughput and a 5G SA connection underperforms a 5G NSA connection or a 4G LTE connection. Wireless devices can provide geolocation tagged cellular wireless network information, e.g., network performance measurements and observed properties, to network-based servers that collate and organize the crowd-sourced cellular wireless network information into a location database. The wireless device can use the cellular wireless network information of the location database for a geolocation at which the wireless device is operating to estimate performance for alternate wireless connections and compare to measured performance of a currently used wireless connection to determine whether to switch wireless RAT connections.

Abstract: Apparatuses, systems, and methods for refreshing a GUTI of a UE. The UE may receive a GUTI from an AMF as part of a registration process. After a timer has expired, the UE may receive a new GUTI from the AMF. The timer may be provided by the UE as a request for use by the AMF. Alternatively, the timer may be used by the UE and the UE may request the new GUTI upon expiry of the timer, e.g., using an existing message or a new message, as desired.

Abstract: A wireless network may include a device that communicates with base stations. The device may include a set of antennas. The network may transmit a message identifying a subset of frequency resources of a frequency band for the device. The subset can include a bandwidth part configuration, a component carrier configuration, and/or a physical resource block configuration. The device may generate wireless performance metric data with the set of antennas using the subset of frequency resources rather than averaging wireless performance metric data across the entire band. The device may identify a best performing antenna based on the performance metric data and may use that antenna to transmit signals. The best performing antenna may be different than when averaged across the entire frequency band, serving to optimize wireless performance particularly when the frequency band has a wide bandwidth.

Abstract: The exemplary embodiments describe devices, systems and methods for implementing various exemplary techniques related to fifth generation (5G) new radio (NR) cell search. A user equipment (UE) selects a frequency band to scan during a cell search procedure and identifies a frequency within the frequency band that is associated with a synchronization signal block (SSB) based on an indication of the frequency stored locally at the UE prior to the cell search procedure. The UE then scans the frequency for the SSB and determines that the SSB has been broadcast by a cell over the frequency.
