The system comprises a control module (2) for determining a trajectory for the physical robot and generating trajectory control data that comprises velocity data and positional data based on the determined trajectory. The system further comprises a first control loop (3), comprising a first feed forward controller (4). The first feed forward controller is configured to receive the trajectory control data, send, via the wireless network (11), and a first velocity command to a first control interface of the physical robot (5). The first velocity command is based on the trajectory data. The first feed forward controller (4) is further configured to receive, via the wireless network, a first set of sensor data from physical robot. The system (1) further comprises a simulated robot implementing a digital twin (9) of the physical robot, and a second control loop (6) comprising a second feed forward controller (7). The second feed forward controller is configured to receive, via the wireless network, a second set of sensor data from the physical robot, determine a second velocity command based on the received second set of sensor data, and send the second velocity command to a second control interface of the digital twin. A corresponding method (100) is also disclosed.

摘要： The present disclosure relates to delivery of data traffic over a wireless connection. In more particular, it relates to methods, a tunneling unit (208), and system for emulating wired connectivity between two or more robot devices (202, 204) and a controller (222). Buffering (212) of data frames, from two or more robot devices, received up-streams a wireless access network (206) is performed. Based on the time-stamps extracted (210) from data frames a relative time offset is determined for the two or more robot devices. Buffered uplink frames are forwarded (216) to the controller in a pre-define order, enabling using the relative time offset when forwarding downlink frames (232), being received over the wireless access network (206), to said two or more robot devices, such the that the downlink frames reach each one of two or more robot devices simultaneously. A deterministic delivery of data frames over a wireless connection is provided.

摘要： Methods and apparatus for identifying a source of quality degradation for a media call flowing in a first direction and a second direction between a mobile-originating user equipment (UE) and a mobile-terminating (MT) UE are presented. In an example method, a network node obtains a set of multiple rules specified respectively for multiple candidate sources of quality degradation for the media call in the first direction. These rules indicate whether a particular candidate source is an actual source of quality degradation based on values of certain key performance indicators (KPIs). The network node identifies, from among the multiple candidate sources of quality degradation, one or more sources of quality degradation by evaluating one or more rules from the set of multiple rules.

摘要： Techniques for enhancing performance in Industrial Internet-of-Things (IIoT) scenarios, including techniques for time-sensitive networking (TSN) and 5G wireless network integration. An example method, performed by a wireless device, comprises receiving system information (SI) from a radio base station (RBS) of a radio access network (RAN), the SI being indicative of support for TSN through the RBS, and establishing at least one TSN stream with an external data network, through the RBS. The example method further includes receiving a first timing signal from the wireless communications network, via the RBS, receiving a second timing signal from the external TSN data network to which the wireless device is connected, comparing the first timing signal to the second timing signal to determine an offset, and transmitting the offset to the wireless communications network.
