Publication number: 20260046914Abstract: An electronic device supports multiple uplink carrier aggregation (UL CA) combinations for various frequency bands. The device includes processors that predict whether a foreground application will be optimized by a high bandwidth UL CA combination, a low uplink transmit switching time UL CA combination, or a UL CA combination having both a higher bandwidth and a lower uplink transmit switching time. The processors select the appropriate UL CA combination and transmit this information to a remote device. The method involves ranking UL CA combinations based on throughput and latency scores, building a user equipment capability information (UCI) message with fewer UL CA combinations, and dynamically updating the UCI message based on hardware changes or application requirements. This approach ensures optimal performance for applications requiring high throughput, low latency, or both.Type: ApplicationFiled: August 8, 2024Publication date: February 12, 2026Inventors: Armin W.

Patent number: 12155789Abstract: A voice call is established between two or more computing devices. The voice call may be, for example, audio only or audio and video. One computing device, referred to as a near-end device, receives a digital representation of background noise captured at another computing device, referred to as a far-end device. The near-end device captures voice audio from the user of the near-end device and adjusts the voice audio based at least in part on the digital representation of the background noise at the far-end device. The near-end device then transmits the adjusted voice audio to the far-end device for playback at the far-end device.Type: GrantFiled: June 20, 2022Date of Patent: November 26, 2024Assignee: Motorola Mobility LLCInventors: Daniel C.

Publication number: 20240163822Abstract: A communication device, method, and computer program product optimize cyclic or linear delay diversity for effective transmit diversity that increases transmit power by first and second transmit chains of the communication device while configured for uplink full power transmission mode 1. Using a precoding matrix codebook for multiple-input multiple-output transmission, a controller of the communication device sequentially configures the first transmit chain to transmit an uplink signal and the second transmit chain to transmit the uplink signal with a different phase shift or time delay value. While sequentially transmitting, the controller monitors a measure of uplink signal quality at a network node for each sequentially changed phase shift or time delay values. The controller determines and uses an optimum value for the phase shift or time delay value that results in an optimum uplink signal quality over the evaluated sequence of different phase shift or time delay values.Type: ApplicationFiled: June 10, 2023Publication date: May 16, 2024Inventors: DANIEL C. CHISU, ARMIN W. KLOMSDORF

Publication number: 20240146367Abstract: A communication device, method, and computer program product reduce power consumption when one or more transmit chains can be inactivated without unsatisfactory uplink communication quality in single data layer transmit diversity (TxDiv) or multiple input multiple output (MIMO) mode. The communication device monitors uplink signal quality of the uplink data stream while connected in single layer mode to a base node using multiple transmit chains. The controller device deactivates transmit chain(s) while the uplink signal quality remains satisfactory. The controller re-activates the inactivated transmit chain(s) in response to the uplink signal quality becoming unsatisfactory.Type: ApplicationFiled: October 28, 2022Publication date: May 2, 2024Inventors: DANIEL C.

Patent number: 11838806Abstract: Techniques for multiple call types for a call event are described and may be implemented via a wireless device to enable multiple connections for wireless calls. For instance, redundant connections for a call event of a wireless device are established via different call types and utilized to exchange call media of the call event. In at least some implementations, call media from the different call types is combined to provide a combined media stream for output as part of the call event. Thus, techniques for multiple call types for a call event are applicable to increase call quality in different scenarios and environments, such as in situations where a primary call connection experiences an anomaly condition that causes quality call degradation.Type: GrantFiled: November 18, 2022Date of Patent: December 5, 2023Assignee: Motorola Mobility LLCInventors: Daniel C.

Patent number: 11637921Abstract: A computing device supports both audible notifications and vibration notifications that are used to notify a user of various different events, such as an incoming voice call or text message. The computing device predicts when a user will have difficulty hearing an audible notification from the computing device due to environmental noise. In response to predicting that a user will have difficulty hearing an audible notification from the computing device due to environmental noise, the computing device enables vibration notifications (if not already enabled) on the computing device. The computing device also optionally communicates with one or more additional devices (e.g., a smartwatch or other wearable device) connected to the computing device to cause those additional devices to also enable vibration notifications. In response to subsequent events for which the user is to be notified, the computing device (and optionally additional devices connected thereto) provides a vibration notification.Type: GrantFiled: September 9, 2019Date of Patent: April 25, 2023Assignee: Motorola Mobility LLCInventors: Daniel C.

Patent number: 11595462Abstract: A near end device is in a call (voice or video) over a communication link with a far end device. The near end device monitors constraints of the near end device, such as environmental noise at the near end device, latency between sequential data packets, signal strength or quality over the communication link, and energy level. The near end device detects when the near end device is having or is soon to have communication difficulty with the call due to one or more of the constraints. In response to detecting that the near end device is having or is soon to have communication difficulty with the call, the near end device communicates one or both of audible feedback and visual feedback to the far end device, notifying the far end device that the near end device is having or is soon to have communication difficulty with the call.Type: GrantFiled: September 9, 2019Date of Patent: February 28, 2023Assignee: Motorola Mobility LLCInventors: Daniel C.

Patent number: 11595873Abstract: A communication device, method, and computer program product mitigate antenna performance degradation that can result from folding or closing the communication device. A controller of the communication device identifies that the communication device is in a marginal coverage area for receiving a downlink in a first radio frequency (RF) band. The controller determines that first and second housings of the communication device are positioned in a first position that has degraded antenna performance for the downlink whereas a second position is not degraded. In response to the housings being in the first position while the communication device is in the marginal coverage area, the controller prioritizes connection to one or more nodes to communicate with the communication device via a second RF band.Type: GrantFiled: November 20, 2020Date of Patent: February 28, 2023Assignee: Motorola Mobility LLCInventors: Md Faisal Abedin, Si Chen, Mohammed R.
