Abstract: Methods, devices, and apparatus to adapt operating parameters for satellite signal reception and transmission by a wireless device to mitigate effects of fading due to specular reflections are described herein. The wireless device measures received signal power levels and compares characteristics of the measurements over an observation duration to at least one fading criteria to determine whether to operate in a normal or adaptive mode. While operating in the adaptive mode, the wireless device alternates between high performance mode time periods and low performance mode time periods. The wireless device indicates to a ground station associated with the satellite in which operating mode the wireless device is operating via an uplink data message transmitted during a data cycle at the start of a high or low performance mode time period. The ground station schedules data transmissions accordingly during subsequent data cycles of the high or low performance mode time periods.

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.

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: The present application relates to improving a roaming service. In an example, user equipment (UE) initiates a cell selection process to choose between a first cell and a second cell. The UE evaluates a first uplink (UL) channel condition of the first cell and a second UL channel condition of the second cell based on the initiation. The UE selects the first cell or the second cell based on the evaluated first UL channel condition and second UL channel condition. The UE initiates a random access channel (RACH) procedure based on the selected first cell or second cell.

Abstract: User equipment may include a transmitter and a receiver coupled to an antenna to enable the user equipment to transmit and receive user data with a base station of the wireless network. However, the user equipment may perform power-consuming searches to determine a base station for connection. Furthermore, the connection may be affected by blockages and transitions during mobility scenarios. As such, it may be beneficial for the user equipment to implement mobility procedures. For example, the user equipment may form links with multiple base stations of a cell cluster for transitioning. In another example, the wireless network may generate a map with locations of base stations and beam characteristics for the user equipment to determine coverage areas and decrease a number of transitions. Still in another example, the user equipment may receive blockage information to predict a blockage and implement mobility procedures to maintain wireless service during a blockage.

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 wireless device may connect, using a first subscriber identity module (SIM), to a first base station according to a first radio access technology (RAT) and a second base station according to a second RAT. The wireless device may also connect, using a second SIM, to a third base station according to the first RAT. The wireless device may, in response to the second SIM performing a call according to the first RAT, disable the first RAT for the first SIM and perform, using the first SIM, data communication according to the second RAT while the call is performed using the second SIM.

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: A user equipment (UE) device may reside in a state of dual connectivity with a master cell group (MCG) and a secondary cell group (SCG), wherein the radio access technologies of the MCG and the SCG are different. While in the dual connectivity state, the UE device may transition to a mode of reduced activity (e.g., processing and/or RF activity) relative to the secondary cell group (SCG) in order to save power, e.g., when traffic flow via the SCG is below a threshold, or when scheduling activity on the SCG is low. Various mechanisms may be employed to reduce activity, e.g., mechanisms such as reduction of beam monitoring, deactivation of secondary cells of the SCG, reduction of number of active antenna elements, employment of longer periods for periodic measurement and reporting processes, etc.

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.
