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

This disclosure is directed to shared antenna tuning. An electronic device may receive a global navigation satellite system (GNSS) tune request to tune a shared antenna to a GNSS signal frequency. The electronic device may then tune the antenna to the GNSS signal frequency and enable a GNSS receiver. The electronic device may also receive a cellular tune request to tune the antenna to a cellular frequency. The electronic device may tune the antenna to a cellular frequency and may deactivate the GNSS receiver or blank the GNSS receiver. In some embodiments, the electronic device may also communicate with a Low Earth Orbit (LEO) satellite. During LEO satellite communication, the electronic device may transmit a signal to blank a GNSS L1 receiver to avoid signal interference with the LEO satellite communication, and activate a GNSS L5 receiver to receive GNSS signals.

Systems and methods for shared antenna tuning

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 wireless device is configured to select a beam and/or an antenna based on detection a detected position and/or orientation of the device relative to a remote device. The device obtains motion data indicating a change in position or orientation of the wireless device. The device determines its pose relative to the remote device. The device accesses a coverage map that associates, for each potential pose for the device with respect to the remote device: an antenna for communicating with the remote device and/or a beam for communicating with the remote device. The device selects a particular antenna and/or a particular beam for communicating with the remote device; and causes transmission or reception of data to or from the remote device by the particular antenna and/or the particular beam.

Sensor-assisted antenna and beam selection for wireless communications

In an example method, a user equipment (UE) of a wireless network determines data for transmission between the UE and a base station (BS) of the wireless network; determines a context of the transmission of the data between the UE and the BS; selects, based on the context, one or more antenna elements of an antenna array of the UE; and forms one or more wireless beams using the one or more selected antenna elements. Further, the UE (i) transmits at least a first portion of the data to the BS using the one or more wireless beams, and/or (ii) receives at least a second portion of the data from the BS using the one or more wireless beams.

Dynamically selecting beam types for wireless communications

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.

Transmission power management for concurrent operating radios

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

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-6GHz 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.

Apparatuses, systems, and methods for high data mode operation in cellular networks. A UE may determine, for an interface to a high-speed cellular network, a categorization from a plurality of categorizations, determine availability of the high-speed cellular network, and select, based at least in part on the categorization and availability of the high-speed cellular network, the interface for a data connection to the high-speed cellular network. The categorization may be one of expensive or not expensive and/or one of a first level associated with a higher compression codec rate or a second level associated with a lower compression codec rate. The UE may receive, from one of the a low-speed cellular network or the high-speed cellular network, carrier plan information for a cellular data service carrier and analyze the carrier plan information to determine desirability of a switch, e.g., from the low-speed cellular network to the high-speed cellular network.

High data mode for enhanced user experience in cellular networks

A user equipment (UE) determines a transmission power for data transmission to a network. The UE determines a specific absorption rate (SAR) limit associated with the UE and determines a transmission power to be allocated to data transmissions based on one or more applications running on the UE and the SAR limit.
