CPC classification number: H04W48/12 , H04L5/0048
Abstract: User equipment in close proximity may transfer data and control information. For example, the user equipment may exchange data or data sets between each other. Each user equipment can receive and transmit data using radio access technologies. A group of user equipments may include active user equipment and passive user equipment. Active user equipment connects with one or more base stations and transfers data on a wireless communication network via the base station. The active user equipment may communicate with other active user equipment and passive user equipment. Passive user equipment may not connect to any base station and/or the wireless communication network and may communicate with other passive user equipment and active user equipment (e.g., via a sidelink, peer-to-peer, or device-to-device channel).

Abstract: An electronic device determines a position of a communicaiton hub of a wireless network. In response to determining a position of a communication hub of a wireless communication network, the electronic device may operate one or more actuators to move the device to adjust the orientation of the device relative to the communication hub. As such, the mobile communicating device may adjust the orientation of the device relative to the communication hub to provide more reliable and/or more efficient communication of data.

Abstract: A mobile communication device is configured to receive updated network data, such as updated Content Delivery Network (CDN) data utilized to access a first network, without accessing the first network and a second network, such as a Wi-Fi or cellular network. The mobile communication device periodically transmits, via a peer-to-peer (P2P) network, a beacon signal indicating a network data request for the updated network data. A rate at which the mobile communication device periodically transmits the beacon signal is based on various criteria, such as an origination date of network data stored on the mobile communication device, an amount of time between the origination date and the present date, a battery health of the mobile communication device, and/or various inputs to the mobile communication device. An additional mobile communication device receives the beacon signal and transmits the updated network data to the mobile communication device.

Abstract: This disclosure relates to methods and devices for transmitting acknowledgment messages on a preferred cell in a carrier aggregation scenario. A user equipment device (UE) establishes a connection with a primary cell and one or more secondary cells, and determines a preferred cell from among the primary cell and the one or more secondary cells based at least in part on one or more quality metrics. The UE may determine the preferred cell at least in part in response to determining that transmission power of the UE has been limited due to a specific absorption rate (SAR) backoff feature of the UE. The UE transmits a notification to a network indicating that the UE intends to transmit an acknowledgement message to the preferred cell, and transmits the acknowledgment message to the preferred cell.

Abstract: In a method of device-to-device communication, efficient power management is provided when a primary device has a low battery level. The primary device can send synchronization signals and discovery messages to secondary devices by looping through a sequence of transmit power values in a sequence of consecutive frames, where the sequence of transmitting values includes a default power value and a reduced power value.

Abstract: A method implemented on a mobile device that starts by receiving a temperature reading from a sensor included on the mobile device. The temperature reading is compared to a threshold temperature and a power cap is set when the temperature reading is greater than the threshold temperature. The power cap is a maximum transmission power of the mobile device. The method then determines if the mobile device is transmitting a critical message. The power cap is released for a period of time if the power cap is set and the mobile device is determined to be sending a critical message. Other embodiments are also described.

Abstract: The embodiments disclosed herein include capturing images via cameras or light sensors of a mobile communication device, processing the image to determine obstructed (e.g., by foliage) portions and unobstructed (e.g., open sky) portions of the images, and generating a grid indicating the obstructed and unobstructed portions. The device may then adjust operating characteristics, such as synchronizing with a communication hub or other mobile communication device, performing a handover with the communication hub or other mobile communication device, determining transmission power or an amount to increase transmission power, selecting an antenna, determining a beam direction, determining a discontinuous reception cycle or a frequency for receiving data, providing an indication to stop or proceed through certain areas (e.g., to take advantage of areas with higher signal quality or avoid areas with lower signal quality), and the like, based on the obstructed and unobstructed portions identified in the grid.
