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.
