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: A method includes receiving an indication to transmit a first set of signals using a first standard (e.g., Long Term Evolution) via a first set of antennas of a radio frequency device and a second set of signals using a second standard (e.g., New Radio) via a second set of antennas. The method also includes transmitting the first set of signals via the first set of antennas using a first power based on positions of the first set and second set of antennas, exposure conditions of the first set and the second set of signals on a user, and/or priorities of the first and the second set of signals. Moreover, the method includes transmitting the second set of signals via the second set of antennas using a second power based on the positions of the antennas, the exposure conditions of the signals on the user, and/or priorities of the signals.

Abstract: Embodiments herein provide 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. 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 is with a cellular connectivity was. 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.

Abstract: 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.

Abstract: 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.

Abstract: A method for playing a movie asset in several playback devices. The method receives a request to play a movie asset and synchronizes clocks between a first device and a second device, which is a portable device. The method signals a start of the playback of the asset through the first and second playback devices, where playback on the second device is synchronized with playback on the first device. The method wirelessly transmits an alert message that identifies the asset through the first and second devices and includes a description of an upcoming or future segment of the asset, where a first version of the segment is played back through the first device. In response to receiving the alert message, the second device becomes configured to select a second version of the segment in accordance with i) user settings of the portable device and ii) the description of the segment.

Abstract: 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.

Abstract: 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.
