  • Publication number: 20220272046
    Abstract: A technique for determining an available delay budget for transmission of a packet by a base station to a user equipment, UE, in a cellular network is disclosed. A method implementation of the technique is performed by the base station and includes receiving a packet from a sending node, the packet including a timestamp set by the sending node when processing the packet, triggering determining a latency of the packet based on a difference between a time determined by the base station upon receipt of the packet and the timestamp set by the sending node in the packet, the base station and the sending node being synchronized in time, and triggering determining an available delay budget for transmission of the packet to the UE based on the latency of the packet.

    Abstract: An apparatus for selecting a transmission mode for wirelessly transmitting a message comprising control information for robotic device control is provided. The apparatus is configured to compare a current message with a previous message to identify a change in the control information, and to select one of a normal transmission mode and a robust transmission mode, wherein the robust transmission mode is selected if a change in the control information is identified. In another variant, the apparatus is configured to obtain a count of consecutively not correctly received messages, and to select one of a normal transmission mode and a robust transmission mode based on the obtained count, wherein the robust transmission mode is selected if the count equals or approaches a threshold. The apparatus is also configured to trigger wireless transmission of the current message with the selected transmission mode.

  • Patent number: 11269039
    Abstract: Position of a transceiver is calibrated using a pair of calibration devices spaced from the transceiver and each other. A calibration wave signal is emitted from one of the calibration devices and detected by the transceiver as well as the other calibration device. The transceiver generates a response wave signal upon receipt of the calibration wave signal which response wave signal is detected by one of the calibration devices. A delay constant for use in distance determination between transceivers is calculated based on the sum of detected transmission and receipt time intervals and the propagation speed of the wave signals.
