Abstract

Methods, apparatuses, systems, etc., directed to performing positioning of a wireless transmit/receive unit (WTRU) while it is in idle mode and/or inactive mode (collectively “idle/inactive mode”) in NR are disclosed herein. Performing positioning, including positioning measurement and/or reporting, in idle/inactive mode may allow for increased positioning accuracy and/or decreased latency of location determination. In various embodiments, a WTRU in idle/inactive mode may transmit a positioning measurement report in various ways, including (i) in a Random-Access Channel (RACH) preamble; (ii) appended to a RACH preamble; and/or (iii) in a Physical Uplink Shared Channel. In various embodiments, a WTRU in idle/inactive mode may transmit uplink-based positioning related reference signals. In various embodiments, a WTRU in an idle/inactive mode may transmit, over a dedicated physical channel, (e.g., downlink) positioning measurement reports and/or reference signals (RSs) for uplink positioning measurements.
