Embodiments herein provide various 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. In an embodiment, 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 with a cellular connectivity was. In an embodiment, 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.

Systems and methods for assisted cellular connectivity

A device, system and method for a user equipment (UE) to report a network resource and capability state to a network for coordinating network resource allocations. The UE is configured to establish a first connection to a first network based on a first subscriber identity module (SIM) of the UE and further configured to establish a second connection to a second network based on a second SIM of the UE. The method includes determining an upcoming first change of a state of the UE with respect to the first connection and transmitting, to the first network, an indication of the first change of state of the UE. The method further includes changing the state of the UE with respect to the first connection.

Reporting framework for dynamic UE capabilities

This disclosure relates to techniques for a wireless device to determine whether to display an indicator of millimeter wave cellular availability. A wireless device may establish a radio resource control connection that includes connectivity with a fifth generation new radio millimeter wave cell. The wireless device may determine to display an indication of millimeter wave cell availability. The wireless device may determine location status information and motion status information for the wireless device. The wireless device may determine when to cease displaying the indication of millimeter wave cell availability after the radio resource control connection is released or the millimeter wave cell is deconfigured based at least in part on the location status information for the wireless device and the motion status information for the wireless device.

Determining whether to display an indicator of millimeter wave cellular availability

Techniques described herein may enable a user equipment (UE) to optimize radio access technology (RAT) and radio resources (e.g., bandwidth parts (BWPs)) when communicating with the network. This may be based on one or more factors or conditions, such as whether the UE is currently using 4th generation (4G) RAT or 5th generation (5G) RAT, whether the UE is in an active mode or idle mode, a BWP used by the UE, whether an application or network service requires a certain throughput, a type of application being used by the UE, an amount of network congestion, and so on. RAT optimization may also be based on whether the UE is using a frequency range 1 (FR1) or frequency range 2 (FR2), whether the UE is stationary or moving, whether the UE is experiencing beam failures, uplink (UL) switches, link quality measurements (LQMs), reference signal received power (RSRP) measurements, and so on.

Systems, methods, and devices for optimizing radio access technology and resource selection

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.

Smart mechanism to manage thermal impact in 5G NR

Reporting potential impacts of sounding reference signal-switching (SRS-switching) to a base station may include determining that SRS-switching is to be performed by a UE. Based on determining that SRS-switching is to be performed, potential impacts to one or more of a plurality of radio access technologies (RATs) caused by performing SRS-switching while sharing radio frequency (RF) front-ends (RFFE) between at least a subset of the plurality of RATS may be processed. The potential impacts may comprise at least one of transmit-blanking (Tx-blanking) and receive-blanking (Rx-blanking) associated with one or more of the subset of RATs. A communication that indicates the potential impacts of SRS-switching may be encoded for transmission to a base station. The base station may also provide priority configurations for determining how to handle Tx-blanking, Rx-blanking, and SRS-skipping associated with SRS-switching.

SRS-switching enhancements for mitigating the impact of conflict and blanking

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.

Smart data mode for 5G wireless devices

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.

5G NR efficient FR1/FR2 operation

This disclosure relates to techniques for providing a framework for supporting custom signaling between a wireless device and a cellular network. A wireless device and a cellular base station may establish a wireless link. The wireless device and the cellular base station may perform custom signaling in accordance with the custom signaling framework.

Framework for supporting custom signaling between a wireless device and a cellular network

A user equipment (UE) passively determines the presence of a cellular network bottleneck in a downlink channel and may take appropriate actions to mitigate the bottleneck. The UE may analyze the transport block size (TBS) of slots of received downlink traffic and assign states the to various slots based on this analysis. Based on these assigned states, the UE may identify a burst of network traffic from network traffic received from the cellular network, and the UE may also determine the burst duration as well as a busy estimation. The UE may determine that the cellular network is experiencing a bottleneck based at least in part on the burst duration and the busy estimation.

Detecting cellular network bottlenecks using data allocation patterns

The exemplary embodiments relate to a user equipment configured to connect to a network that supports simultaneous connection to a first radio access technology (RAT) and a second RAT. The UE may receive coverage information associated with the first RAT and a cell of the second RAT, receive an indication of the current UE location relative to the cell of the second RAT and determine whether the first RAT is available for camping based on the coverage information and the indication of the current UE location relative to the cell of the second RAT.

Identifying new radio coverage availability in non-standalone mode

Wireless devices, networks and methods may operate to have a wireless device cause a base station to trigger voice call continuity handovers responsive to the quality of the cellular radio link in addition to the base station triggering such handovers based on location or mobility. Furthermore, wireless communication devices may also perform monitoring of multiple buffers operating within the wireless communication device and associated with different respective communication layers, in addition to monitoring the quality of the cellular radio link, to perform intelligent dropping/discarding and/or scheduling of packets at the wireless communications device. Any one or more of these features may improve the ability of the wireless communications device to achieve stated Voice over Long Term Evolution (VoLTE) performance benchmarks in the context of the realities of current VoLTE networks.
