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 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.

Abstract: The described embodiments regard detecting a bandwidth part (BWP) mismatch between a wireless device and a cellular wireless network base station and performing mitigation to correct for the BWP mismatch. The wireless device can detect a BWP mismatch, based on content of a downlink control information (DCI) message indicating to switch BWP configurations, which is inconsistent with a scheduled downlink resource or granted uplink resource indicated in the DCI message occurring before completion of a BWP switching delay time period. The wireless device can monitor for DCI messages, after switching BWP configurations, in accordance with a previous BWP configuration for a monitoring time period to confirm use of the new BWP configuration or to detect a BWP mismatch. Responsive to detecting a BWP mismatch, the wireless device switches back to the previous BWP configuration without waiting to complete the BWP switching delay time period for switching BWP configurations.

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: Communication device may include a transmitter and a receiver respectively coupled to one or more antennas to communicate (e.g., transmit or receive signals) with a base station. The communication device may receive an operating characteristic of a cellular modem within the communication device operating in a first cellular configuration and determine if the operating characteristic are greater than a threshold. The operating characteristic may include power and/or temperature. The threshold may include a power budget and/or a temperature threshold. If the operating characteristic is greater than the threshold, then the communication device may determine a control effort value based on the operating characteristic and the threshold. The communication device may map the control effort value to a second cellular configuration, which may correspond to reduced operating characteristics in comparison to the first cellular configuration.

Abstract: An electronic device may be provided with first and second sidewalls, a rear wall, and a display. Multiple antenna panels may be used to convey radio-frequency signals at frequencies greater than 10 GHz. A first antenna panel may radiate through the display while second and third panels radiate through the first and second sidewalls. The second and third panels may be tilted at non-zero angles with respect to the sidewalls. The non-zero angles may be of opposite sign. The non-zero angles may have the same magnitude. The magnitude may be equal to 15 degrees, as one example. Tilting the panels in this way may allow the panels to collectively cover as much of a sphere around the device as possible, including out of coverage areas behind the rear wall caused by conductive material in the rear wall, without requiring additional panels to be disposed within the device.

Abstract: An electronic device may include wireless circuitry with a phased antenna array that conveys radio-frequency signals using signal beams of first and second orthogonal polarizations. The array may sweep over a set of signal beam pairs, each including a respective combination of signal beams of the first and second polarizations. The wireless circuitry may gather performance metric values for each of the polarizations and signal beam pairs. The circuitry may generate a filtered set of signal beam pairs by removing signal beam pairs having performance metric values that differ from a maximum of the wireless performance metric values by more than a threshold. The circuitry may select a signal beam pair from the filtered set having a minimum polarization imbalance. The array may concurrently convey first and second wireless data streams using the selected signal beam pair. Minimizing polarization imbalance may maximize overall data throughput for the device.

Abstract: This application describes methods and apparatus to allocate uplink (UL) power dynamically across multiple parallel radio frequency links for wireless devices. The wireless device sets an initial maximum transmit power level (MTPL) for each UL radio link of multiple radio links used for UL traffic based on a duty cycle prediction for the respective UL radio link. The wireless device adjusts the initial MTPL for each UL radio link based on a predicted data throughput for the UL radio link relative to a total predicted data throughput for all UL radio links. The adjusted MTPL for each UL radio link can be also reduced when the UL radio link uses UL multiple input multiple output (MIMO) transmission via multiple antenna ports, e.g., by apportioning the adjusted MTPL among the multiple antenna ports of the UL radio link equally.

Abstract: An electronic device having multiple antenna groups for data communication may determine a temperature of a first antenna group and determine a power gain of a second antenna group. The electronic device may communicate using the second antenna group in response to determining that the temperature of the first antenna group exceeds a temperature threshold and the power gain of the second antenna group exceeds a gain threshold. In some embodiments, the electronic device may receive communication link preferences, determine an antenna group that is disposed outside of thermal hotspots of the electronic device, and determine a beam that enables the communication link preferences via the antenna group. The electronic device may then transmit or receive data via the antenna group by forming the beam.

Abstract: A communications network may be used to convey Short Message Service (SMS) messages using the Internet Protocol (IP). User equipment may transmit an SMS-over-IP Session Initiation Protocol (SIP) message to wireless equipment over a high-bandwidth communications link. The wireless equipment may route the SMS-over-IP SIP message to the ePDG. When the high-bandwidth link is unavailable, the user equipment may transmit a compressed message to the proxy server over a low-bandwidth communications link. The proxy server may convert the compressed message into an SMS-over-IP SIP message that is transmitted to the ePDG. The proxy server may serve as a proxy for the first user equipment from the perspective of the ePDG. This may allow SMS message data to continue to be conveyed through the communications network even when the high-bandwidth communications link becomes unavailable.

Abstract: Disclosed are methods, systems, and computer-readable medium to perform operations including receiving, from a base station, an indication to accumulate a transmit power control (TPC) adjustment value, the accumulated TPC adjustment value used to calculate an uplink (UL) transmit power; detecting at least one UE action that triggers adjusting the accumulated TPC adjustment value; and in response to detecting the at least one UE action, adjusting the accumulated TPC adjustment value.

Abstract: A wireless communication device receives an average transmission power limit for a time period, and determines a first MTPL for a first time of the time period by setting the first MTPL to the average transmission power limit. The wireless communication device then transmits a signal at the first time using a first transmission power not to exceed the first MTPL. If the first transmission power is less than the first MTPL, then the wireless communication device determines residual transmission power based on a difference between the first MTPL and the first transmission power. The wireless communication device determines a second MTPL for a second time of the time period by adding the residual transmission power to the first MTPL. The wireless communication device then transmits a signal at the second transmission power not to exceed the second MTPL.

Abstract: In an example method, a first device determines first network resources that have been activated for exchanging data with one or more second devices via a wireless network, and determines, for each of the first network resources, a time duration of a respective burst transmission performed using that first network resource. The first device determines whether to (i) activate second network resources for exchanging data with the second devices and/or (ii) deactivate one or more of the first network resources for exchanging data with the second devices. In response, the first device activates the second network resources and/or deactivates the one or more of the first network resources.

Abstract: This application describes systems and processes for beam selection performance refinement in static conditions of wireless devices (e.g., user equipment UE). A data processing system of the UE is configured to perform a beam scan for testing multiple high gain candidate beams on a physical downlink shared channel (PDSCH) and link adaptation (LA) channel state information reference signal (LA-CSI-RS) while the UE is not moving and the data processing system of the UE determines that the channel is stable. The data processing system is configured to refine a given beam choice based on a determined capacity of the beams (e.g., from PDSCH signaling and/or LA-CSI-RS signals) to optimize data throughput.
