  • Patent number: 11637783
    Abstract: A user terminal emulation server maintains a database identifying network addresses, UI capabilities, and communication protocols of I/O user devices. Communication sessions are established between a user terminal emulation application and a network entity and I/O user devices proximately located to a user and provide a combined I/O user interface. Delay profiles are determined between the application and the I/O user devices. A downlink flow from the network entity is split into a plurality of downlink flow components assigned to the I/O user devices. For each of the downlink flow components, the server formats the component for transmission to the assigned I/O user device, initiates transmission of the formatted downlink flow component to the assigned I/O user device, and controls timing for when the formatted downlink flow component is transmitted to the assigned I/O user device based on the delay profile associated with the assigned I/O user device.

  • Patent number: 11584268
    Abstract: A display unit in a motor vehicle presents information to a first user located in a personnel site. A frame carries the personnel site and a suspension system between the frame and the personnel site has at least one adjustable suspension characteristic. While the motor vehicle is being operated, a control system repeatedly determines a first gaze point of the first user on the display unit. Variations in a position for the first gaze point over time are analyzed; and in response thereto, the control system generates a first control signal to the suspension system so as to reduce a fluctuation of the position for the first gaze point, if a repositioning of the first gaze point is out of synchronization with a displacement of the display unit.

  • Publication number: 20230043517
    Abstract: A method is disclosed herein for reducing energy consumption in a wireless device. A wireless device (e.g., a user equipment) can provide an indication to a network node (e.g., a base station) to indicate that the wireless device will prioritize energy consumption reduction over some network requirements (e.g., latency and/or scheduling flexibility requirements). Accordingly, the wireless device can perform certain power-saving actions to reduce energy consumption. The network node, upon receiving the indication from the wireless device, can perform certain network-related actions to assist the wireless device in reducing energy consumption. As a result, it is possible for the wireless device to reduce energy consumption and complexity, thus helping to prolong battery life in the wireless device.

  • Patent number: 11546934
    Abstract: A network node transmits a scheduling configuration, over a Single Cell Multicast Control Channel, that indicates whether a single transport block or multiple transport blocks of a Single Cell Multicast Traffic Channel are scheduled. The network node may then transmit a transport block in accordance with the scheduling configuration. Correspondingly, a user equipment receives the scheduling configuration. The UE may then receive a transport block in accordance with the scheduling configuration.

  • Publication number: 20220239725
    Abstract: A user terminal emulation server maintains a database identifying network addresses, UI capabilities, and locations of I/O user devices. Communication sessions are established between first and second user terminal emulation applications and respective first and second I/O user devices proximately located to respective first and second users and which provide acceptable combined I/O user interfaces to the first and second users. When a direct path criterion is satisfied for creating a direct traffic flow, a traffic flow that was from the first I/O user devices to the first user terminal emulation applications is redirected to now be from the first I/O user device to the second I/O user device without passing through either of the first and second user terminal emulation applications.
