Abstract: Systems, methods, apparatuses, and computer program products for duty-cycle based positioning sounding reference signals. A method may include receiving, at a user equipment, configuration information of at least one periodic positioning sounding reference signal. The configuration information may include at least one time interval and at least one transmission resource associated with the at least one time interval. The method may also include transmitting the at least one periodic positioning sounding reference signal to a network entity based on the configuration information. The at least one periodic positioning sounding reference signal may be in a first transmission status or a second transmission status in accordance to the at least one time interval. The at least one time interval may occur periodically.

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.
