  • A Network Node, a First Wireless Device, a Second Wireless Device and Methods Therein for Enabling a Timing Reference
    Publication number: 20240147395
    Abstract: A method performed by a network node (110) in a wireless communications network (100) for enabling a timing reference in a second wireless device (122) for use in Sidelink, SL, transmissions over a SL communication link (133) with a first wireless device (121) is provided. The network node estimates (201) a propagation delay of SL transmissions over the SL communication link (133) between the first and second wireless device (122). Then, the network node (110) transmits, to the second wireless device (122), timing reference information based on a timing reference originating from a time reference node in a wireless communications network (100), and on the estimated propagation delay of SL transmissions over the SL communication link (133) between the first and second wireless device (122). A network node (110) for enabling a timing reference in a second wireless device (122) for use in SL transmissions over a SL communication link (133) with a first wireless device (121) is also provided.

  • METHODS AND APPARATUSES FOR RECEIVER (Rx) - TRANSMITTER (Tx) ROUND TRIP TIME ESTIMATION
    Publication number: 20240057004
    Abstract: Systems, methods, apparatuses, and computer program products for Rx-Tx RTT estimation are provided. One method may include transmitting, by a network element, the reference signal to another network element and recording a time stamp (t0) of a time of transmission of the reference signal, and receiving an estimated Rx-Tx measurement from said another network element and recording a time stamp (t3) of a time of receipt of the estimated Rx-Tx measurement. The method may also include calculating a Rx-Tx measurement at the network element based on a difference between the time stamp (t0) of the time of transmission of the reference signal and the time stamp (t3) of the receipt of the estimated Rx-Tx measurement, and determining a propagation delay based on a difference between the received estimated Rx-Tx measurement and the calculated Rx-Tx measurement.

  • MACHINE LEARNING MODEL VALIDATION FOR UE POSITIONING BASED ON REFERENCE DEVICE INFORMATION FOR WIRELESS NETWORKS
    Publication number: 20240057022
    Abstract: A method may include receiving, by a first user device from a network node or a second user device, 1) a positioning measurement report including at least one positioning measurement measured by a reference device, and 2) reference positioning-related information to be used for testing and/or validating a machine learning model; determining estimated positioning-related information as outputs of the machine learning model based on at least a portion of the positioning measurement report as inputs to the machine learning model; determining a performance indication of the machine learning model based on the reference positioning-related information and the estimated positioning-related information, wherein the performance indication indicates a performance or accuracy of the machine learning model; and performing, by the first user device, an action based on the performance indication.

  • Industrial Automation with 5G and Beyond
    Publication number: 20200259896
    Abstract: 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.
