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.

Abstract: Methods and apparatuses for receive (Rx) beam selection are described herein. A wireless transmit/receive unit (WTRU) may be configured to receive, from a base station (BS), configuration information for joint communication and sensing (JCS) reference signals. The configuration information may include resources for reference signal transmission and resources for measurement reporting. The WTRU may be further configured to receive, from the BS, an indication to activate a subset of the resources for JCS reference signal transmission. The WTRU may be further configured to transmit, a plurality of JCS reference signals using the activated subset of resources for reference signal transmission. The WTRU may be further configured to measure, via a plurality of Rx beams, a backscatter power associated with each of the transmitted plurality of JCS reference signals. The WTRU may be further configured to calculate beam blockage statistics based on the measured backscatter power.

Abstract: A WTRU may track parameters associated with the WTRU or target WTRUs. The parameters may be associated with positioning and/or sidelink communications. The WTRU may receive a configuration for transmission of reference signals to target WTRUs. The WTRU may transmit one or more reference signals on one or more configured sidelink resources. The WTRU may receive respective measurement report(s) from respective target WTRU(s) (e.g., a target WTRU may receive a reference signal transmitted by the WTRU and send an associated measurement report). The WTRU may be configured to send the received target WTRU measurement(s) to the network entity. The WTRU may send each of the received measurements. The WTRU may send the received measurement(s) if condition(s) are satisfied. For example, if a first measurement associated with a first measurement report from a first target WTRU exceeds a first threshold, the WTRU may send the first measurement to the network entity.

Abstract: Systems, devices, and methods for operating in an unlicensed band are disclosed herein. In one example, a device may receive configuration information that includes a maximum channel occupancy time (MCOT) and a plurality of parameters including a plurality of transmission opportunity windows (TOWs). Based on the configuration information, the device may split a transmission into a plurality of bursts that may be grouped into sets of bursts based on how many bursts fit within a TOW. The number of bursts in a set of bursts may be less than or equal to the MCOT. The device may perform a clear channel assessment (CCA) to determine if the channel is busy and to determine a start time within the TOW for the bursts. The device may then transmit the set of bursts for that TOW, where each burst may have a burst indicator (BI).
