Abstract: Methods and apparatuses for receive (Rx) beam selection are described herein. In one example, a method includes receiving configuration information indicating resources for receiving a first set of reference signals from one or more transmit/receive points (TRPs) using a first set of receive (Rx) beams, one or more first resource sets for a second set of reference signals, and one or more second resource sets for transmitting a measurement report. The method includes transmitting a measurement report using one of the one or more second resource sets. The measurement report is based on measurements associated with one or more reference signals of the second set of reference signals. The method includes determining a second set of Rx beams. The method includes receiving the first set of reference signals from the one or more TRPs using the second set of Rx beams.

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.
