Abstract: An apparatus, method and computer program is disclosed relating to positioning. For example, the apparatus may comprise means for operating the apparatus in a first operating state of a plurality of predetermined operating states as part of a positioning process involving communications with one or more remote nodes. The apparatus may also comprise means for identifying one or more trigger events and means for selecting a different one of the operating states, based at least on: the first operating state, and the presence or absence of one or more trigger events. The apparatus may transition from the first operating state to the selected different operating state, wherein the plurality of predetermined operating states may comprise a target state, an anchor state, a positioning reference unit (PRU) state, and a standby state.

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: Disclosed herein are systems, methods and/or computer programs for determining time and/or angle-based measurements for use in position determination. The apparatus may comprise means for receiving, at a plurality of antennae, a reference signal associated with positioning and determining cross-correlation values comprising a cross correlation between the reference signal received at each antenna and a known reference signal associated with positioning. There may also be provided means for estimating a channel response for a reference antenna of the plurality of antennae using the cross correlation values, the known reference signal and an antenna correlation comprising a known relationship between a channel response of each antenna of the plurality of antennae and the channel response of the reference antenna, and determining a time of arrival and/or an angle of arrival of the received reference signal based on the estimated channel response for the reference antenna.
