Abstract: Various example embodiments are described in which a network node transmits to a user device preconfiguration information for a plurality of on-demand positioning signal (ODPS) preconfigurations. An ODPS preconfiguration may be selected and communicated. The transmitted ODPS preconfiguration may be a request for transmission, or a notice of transmission, of the selected ODPS. An ODPS, which is associated with or based on the selected ODPS preconfiguration, may be transmitted. The ODPS may include any positioning signal (e.g., any signal that may be used for positioning) that may be transmitted upon request or as needed, and, e.g., may include downlink on-demand positioning reference signals (ODPRS), uplink on-demand sounding reference signals (ODSRS), or other positioning or reference signal.

Abstract: Systems, methods, apparatuses, and computer program products for a switching machine learning functionality based on resource availability. A method may include executing a machine learning functionality, feature, or model at a first network element. The method may also include monitoring a machine learning resource at the first network element that impacts performance of the machine learning functionality, feature, or model. The method may further include indicating, to a second network element based on the monitoring, a machine learning-related resource availability impacting performance of the machine learning functionality, feature, or model. In addition, the method may include receiving, from a third network element, a configuration for an action to be executed by the first network element based on the machine learning-related resource availability impacting performance of the machine learning functionality, feature, or model. Further, the method may include executing the action.

Abstract: Embodiments of the present disclosure disclose methods and apparatuses for sidelink positioning. A first terminal device transmits capability information of the first terminal device along with a positioning reference signal (PRS), and the capability information indicates a capability to provide the location information of the first terminal device. Then the first terminal device receives a request for the location information of the first terminal device from a second terminal device. Based on receiving the request, the first terminal device transmits the location information along with a subsequent PRS. As such, in embodiments of the present disclosure, the first terminal device may transmit location information according to the request of the second terminal device. Thereby the sidelink positioning performance is improved.
