This application describes systems and processes for sensor-assisted antenna and beam selection for wireless networks. The systems and processes are configured to detect out of coverage (OoC) scenarios and perform beam management in response to detecting the OoC scenario. The systems and methods are configured to perform beam management during baseband interruption scenarios. In each scenario, the device (e.g., user equipment UE) is configured to determine whether the UE is static or mobile.

Sensor-assisted millimeter-wave beam management

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.

Dynamic maximum transmission power

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.

Dynamically allocating network resources for exchanging data using wireless networks

A wireless device can perform non-line-of-sight detection. The wireless device may establish a wireless link with another wireless device using a wireless channel. The wireless device may perform one or more channel measurements for the wireless channel. The wireless device may determine whether a line-of-sight path is available for the wireless channel based at least in part on the one or more channel measurements. The wireless device may determine whether to trigger beamforming selection, antenna selection, and/or any other link maintenance operations based at least in part on the determined line-of-sight availability.

Non-line-of-sight detection

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

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.

Beam selection refinement for wireless communication in static conditions

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.

Dynamic power budget allocation using individualized MTPL per radio link for uplink transmission

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

The present invention generally relates to a management of a wireless interface of a device; the management comprises: monitoring of at least one component of the device, other than a wireless network element; switch a power state of the wireless interface to another power state according to the monitored activity.

Method of management of a wireless interface of a device and corresponding wireless device

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.

Electronic devices having tilted antenna arrays

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.

Electronic devices with polarization management capabilities

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.
