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

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

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

A system and method for operation of a user equipment (UE) to determine a cellular network bottleneck in a downlink channel, and an apparatus for use in a UE for determining the same. A UE may determine a burst of network traffic from network traffic received from the cellular network during a series of transmission time intervals. The UE may analyze resource allocations to the UE during the burst to determine an extent to which the cellular network is busy. The UE may determine that the cellular network is experiencing a bottleneck based at least in part on the analysis of the resource allocations to the UE in the burst.

Detecting cellular network bottlenecks through analysis of resource allocation patterns

Described herein are systems and methods for improved transitions continuity between wireless protocol states. One embodiment relates to a method including, at a user equipment ('UE'), establishing a connection to a first wireless network in accordance with a first wireless communication protocol, wherein the first wireless communication protocol is used for voice communications and data communications between the UE and the first wireless network, receiving a user request to disable the voice communications with the first wireless network, registering for voice communications with a second wireless network in accordance with a second wireless communication protocol, and maintaining the connection to the first wireless network to continue data communications between the UE and the first wireless network, wherein the UE simultaneously operates in the first wireless communication protocol and the second wireless communication protocol.

Systems and methods for improved transitions continuity between wireless protocols

A device, system, and method persists network registration rejection causes. The method is performed at a device connected to a network and comprising a temporary memory and a persistent memory, the device using the data stored in the temporary memory when performing network registration operations. When a power cycle is detected, the method includes determining whether there is persistent data in the persistent memory for a first attempt to register with the network prior to the power cycle, the persistent data including a rejection cause for the first attempt. When there is the persistent data in the persistent memory, the method includes determining whether the persistent data is valid for a second attempt to register with the network after the power cycle. When the persistent data is valid, the method includes generating and storing cause data based on the persistent data in the temporary memory prior to the second attempt.

A device, system and method for initiating cell selection. The method is performed at a device connected to a network and camped on a first cell of the network. The method includes determining whether the device has successfully synchronized with the first cell. When the device is unable to synchronize with the first cell, the method includes determining whether at least one further cell satisfies predetermined reselection criteria and determining whether the at least one further cell satisfies initial cell selection criteria. When the at least one further cell satisfies the initial cell selection criteria, the method includes initiating an initial cell selection.

Apparatus, systems and methods for initiating a cell selection

Apparatuses, systems, and methods for multi-SIM user equipment (UE) devices to perform system selection. A UE may determine to perform system selection for a first SIM of the UE. Information, such as serving cell and/or neighboring cell information, may be obtained from a second SIM of the UE. System selection for the first SIM may be performed based at least in part on the information obtained from the second SIM.

System selection for multi-SIM devices

Apparatuses, systems, and methods for multi-SIM user equipment (UE) devices to perform data operations with a packet data network of a carrier associated with a first SIM of the UE. An indication of a requested data operation with the packet data network of the carrier associated with the first SIM of the UE may be received. The UE may be operating in a dual SIM mode in which the packet data network of the carrier associated with the first SIM of the UE is unavailable. It may be determined if one or more conditions for performing the requested data operation are present and if a data path to perform the requested data operation is available. The requested data operation may be performed if the one or more conditions for performing the requested data operation are present and if a data path to perform the requested data operation is available.

Carrier network access for multi-SIM devices

An apparatus, system, and method optimize a manner in which carrier aggregation (CA) is used. The apparatus comprises a transceiver and processor. The transceiver is used to establish a connection with a network including first and second network components used for a CA functionality. The processor implicitly deactivates the SCell while the CA functionality is enabled by the network by determining that the CA functionality is enabled by the network, determining that the SCell is one of out-of-service (OoS) and effectively OoS when the second network component is reachable by the apparatus and a connection parameter with the second network component is below a predetermined threshold, transmitting a channel quality indicator (CQI) value of zero for the SCell to the first network component to implicitly deactivate the SCell, and utilizing a low power consumption state where monitoring of the SCell is terminated.

Apparatus, system, and method for toggling carrier aggregation

Apparatuses, systems, and methods for multi-SIM user equipment (UE) devices to perform emergency calling. A UE may receive an indication to initiate an emergency call. The UE may select a cell on which to initiate the emergency call. If a serving cell of a first SIM of the UE is not available for the emergency call, the UE may utilize information from a second SIM of the UE as part of selecting the cell on which to initiate the emergency call. The information from the second SIM may include an indication of a serving cell of the second SIM. Alternatively or in addition, the information from the second SIM may include an indication of one or more neighboring cells of the second SIM. The emergency call may be initiated via the selected cell using the first SIM.

Emergency calling for multi-SIM devices

A UE may initiate a background scan to upgrade RAT while camped on a first system in response to an occurrence of a first condition. The first system may include a first PLMN that operates according a first RAT. The UE may determine a second system operates according to a second RAT that provides upgraded service as compared to the first RAT. The second system may be included in one or more systems found during the background scan. The UE may attempt to register on the second system based on the second PLMN operating according to the second RAT. The first and second PLMNs may each have an associated operator preference and the first PLMN may be preferred over the second PLMN.
