Abstract: Disclosed are techniques for wireless communication. In an aspect, a network entity sends, to a user equipment (UE), a notification of a plurality of direct current (DC) tones of a plurality of network nodes configured to transmit a plurality of positioning signals to the UE, and receives, from the UE, a position of the UE, a plurality of positioning related measurements of the plurality of positioning signals, or any combination thereof. In an aspect, a UE receives, from a network entity, a notification of a plurality of DC tones of a plurality of network nodes, receives, from the plurality of network nodes, a plurality of positioning signals, and determines a plurality of positioning related measurements of the plurality of positioning signals based on locations of the plurality of DC tones indicated in the notification.

Abstract: Disclosed are techniques for communication. In an aspect, a first node determines equiphase contour information associated with an antenna of the first node at one or more carrier frequencies, and transmits an indication of the equiphase contour information to a second node. In another aspect, a device determines equiphase contour information associated with an antenna of a first node at one or more carrier frequencies, and corrects measurement information associated with a carrier phase-based position estimation session based at least in part on the equiphase contour information.

Abstract: Aspects are directed to multiple carrier phase measurements associated with a positioning frequency layer (e.g., instead of measuring and/or reporting a single carrier phase measurement per positioning frequency layer at the central frequency of the positioning frequency layer). Other aspects are directed to reduced positioning frequency layer bandwidth for reference signal for positioning measurements (e.g., for reduced capability or “RedCap” user equipments). Other aspects are directed to differential carrier phase measurement reporting.

Abstract: In an aspect, a wireless node performs measurements of an RS-P (e.g., PRS or SRS-P) on different sub-bands of an RS-P resource. The wireless node transmits separate indications of the measurements in a measurement report to a position estimation entity. The position estimation entity determines a positioning estimate of the UE based in part on the measurement report.

Abstract: Disclosed are techniques for wireless communication. In an aspect, repeater receives a muting pattern configuration associated with at least one positioning reference signal (PRS) transmitted by a base station, the at least one PRS comprising one or more PRS resources of at least one PRS occasion, receives at least one PRS resource of the one or more PRS resources from the base station, and mutes the at least one PRS resource based on the muting pattern configuration.

Abstract: Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) may determine that the UE is or will be at a location within a calibration region. The UE may report, to a network entity, location information, the location information being associated with the location within the calibration region. In an aspect, a network entity may obtain calibration error information associated with a user equipment (UE) and a calibration region. The network entity may send the calibration error information to the UE, to a base station, or to combinations thereof.

Abstract: Disclosed are techniques for wireless communication. In an aspect, one or more processing devices may identify a set of candidate anchor nodes based on a target node. The one or more processing devices may identify a set of candidate anchor locations based on location information of the target node, location information of the set of candidate anchor nodes, mobility capabilities of the set of candidate anchor nodes, or a combination thereof. The one or more processing devices may instruct at least a subset of the set of candidate anchor nodes to move based on the set of candidate anchor locations. The one or more processing devices may configure the set of candidate anchor nodes and the target node to engage in positioning operations at a positioning time to determine a position estimation of the target node.

Abstract: Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) identifies a set of positioning sources, each positioning source comprising a positioning reference signal (PRS) resource, a PRS resource set, a PRS frequency layer, and/or a transmission/reception point (TRP). From the set of positioning sources, the UE identifies a consistency group comprising a collection of positioning sources grouped based on expected values of at least one metric of a reference signal from each positioning source, measured values of the at least one metric for the reference signal from each positioning source, and an error threshold. The UE identifies one or more subsets of positioning sources within the consistency group, each subset having at least one metric error value. The UE reports, to a network entity, information about the consistency group and information about at least one of the subsets of positioning sources within the consistency group.

Abstract: Techniques are provided for configuring on-demand positioning reference signal (PRS) resources in double difference (DD) positioning methods. An example method for providing an on-demand positioning reference signal request includes receiving a plurality of positioning reference signal measurement values from a target user equipment and at least one reference node, determining one or more on-demand positioning reference signals based at least in part on signal identification information associated with each of the plurality of positioning reference signal measurement values, and sending an indication of the one or more on-demand positioning reference signals to either of the target user equipment, the at least one reference node, or both.
