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.

Abstract: An electronic device includes a transmitter and processing circuitry. The processing circuitry determines trends of positions (e.g., elevation angles) of communication nodes and compare the trends of the positions. Based on the comparison between the trends of the positions, the processing circuitry selects a communication node for communication and uses the transmitter to transmit a signal to the selected communication node.

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: An electronic device may include radios that transmit signals using antennas. Control circuitry may assign radio-frequency exposure (RFE) budgets to the radios. The control circuitry may classify and predict attributes of application data for transmission over the radios, may generate a per-radio data prediction based on the classified attributes, and may generate the RFE budgets based on the classified attributes. Each radio may transmit application data based on its data prediction and according to its RFE budget. A dynamic portion of the RFE budget may be reserved for control signaling. RFE planning in this way may ensure that the device optimally utilizes its RFE budget, increasing overall RFE during some time periods so sufficient transmit power is available, and ensuring that RFE is distributed across the radios depending on the amount and criticality of the data to be transmitted by each radio.

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 that a first network is inaccessible and that non-prioritized services associated with a second network are unavailable. In response, the electronic device communicates non-prioritized data via a third network. Additionally, in response to determining that prioritized services associated with the second network are available, the electronic device transmits a priority message using the second network while communicating the non-prioritized data via the third network. In response to determining the first network is accessible, the electronic device communicates additional non-prioritized data and an additional priority message using the first network.

Abstract: This disclosure provide various techniques for decreasing the time it takes user equipment to tune away from a compromised network connection. By more quickly detecting a signal characteristic issue (e.g., signal quality issue) in the compromised signal and performing mitigation actions, the user equipment may decrease power consumption and increase data throughput. The signal quality issue may be detected by monitoring the location of the user equipment, a channel impulse response of the user equipment, and/or a block error rate (BLER) of a signal, among other methods. The data obtained may be fed into confidence validation logic, which may determine a level of confidence that the signal quality issue may cause a weak or broken connection between the user equipment and a network. The confidence validation logic may, based on the determination, operate the user equipment in an active state, a suspend state, or a release state.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for communicating in a first radio access technology (RAT) and a second RAT. A user equipment (UE) can receive, from a first base station using the first RAT, first configuration information for the UE to communicate with a second base station via the second RAT; and receive, from the first base station using the first RAT, a downlink message to enable a communication link between the UE and the second base station via the second RAT. The downlink message includes second configuration information for the UE to communicate with the second base station via the second RAT. The UE can establish the communication link between the UE and the second base station using the second RAT based on a link configuration obtained from the first configuration information and the second configuration information.
