Abstract: A first wireless device receives, from a second wireless device, one or more of an indication of a maximum number of measurement reports or an indication of a threshold probability associated with at least one of an LOS probability or an NLOS probability for a plurality of signal or beam paths. The first wireless device calculates at least one of an LOS probability or an NLOS probability of at least one signal or beam path of the plurality of signal or beam paths. The first wireless device transmits, to the second wireless device, one or more indications of signal or beam information associated with the at least one signal or beam path based on one or more of the maximum number of measurement reports or the threshold probability, the one or more indications of signal or beam information including at least one of the LOS probability or the NLOS probability.

Abstract: Described are methods, systems, and devices for processing a Positioning Reference Signal (PRS) or other reference signal usable for determining a position of a User Equipment (UE). In some aspects, a UE is configured to report to a network entity information indicating a number of receive (Rx) chains used to determine one or more positioning measurements, thereby indicating the amount of uncertainty in the positioning measurement(s) and the precision of a resulting position estimate. In some aspects, a UE is configured to receive multiple PRS signals that at least partially overlap in time and to process each PRS using a separate set of Rx chains to obtain positioning measurements. As part of the processing of a PRS, the UE may align a search window to the PRS. In this manner, different search windows can be maintained for different PRS signals to maximize the signal-to-noise ratio of each PRS.

Abstract: Techniques for positioning assistance data (AD) delivery for reduced signaling overhead may comprise determining a combined positioning AD for a requesting user equipment (UE) based at least in part on the area ID in which the requesting UE is located. The combined positioning AD may include positioning AD for the first area and one or more additional areas. For each of the area, the positioning AD may comprise information regarding Positioning Reference Signal (PRS) resources, Base Station Almanac (BSA) information, or both, to be used for positioning the requesting UE within the respective area. The first area and the one or more additional areas may comprise cells of the wireless communication network or sidelink (SL) group zones.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) may receive positioning assistance data for a plurality of cells, the positioning assistance data including at least a first positioning reference signal (PRS) configuration for a first cell of the plurality of cells and a second PRS configuration for a second cell of the plurality of cells. The UE may perform a handover from the first cell to the second cell during a positioning session with at least the first cell and the second cell. The UE may, after the handover, measure PRS from the second cell based on the second PRS configuration.

Abstract: Techniques described herein provide for a mobile device communicating a timing quality metric related to an uplink (UL) signal for UL and/or downlink-uplink (DL-UL) positioning techniques. The timing quality metric can be indicative of an accuracy of the transmission timing of one or more reference signals (e.g., in relation to a downlink (DL) signal or other UL reference signal) and may be communicated using an indexed and/or enumerated value. This information can be included as an information element (IE) in a report provided by the mobile device to a receiving network entity or location server.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) receives a set of antenna parameters for a plurality of antenna ports of a transmission-reception point (TRP), obtains positioning measurements of a plurality of positioning reference signal (PRS) resources transmitted on the plurality of antenna ports, reconstructs an underlying physical channel between the TRP and the UE based on the positioning measurements of the plurality of PRS resources, and determines a downlink angle of arrival (DL-AoD) measurement from the TRP to the UE based on the reconstructed underlying physical channel.

Abstract: In an aspect, an LMF component may determine to trigger positioning-related action(s) at a UE. The LMF component may request that a serving BS of the UE trigger the positioning-related action(s). The serving BS may transmit a DCI communication with a CSI request field (e.g., that triggers at least CSI reporting, or triggers positioning-related action(s) only). The CSI request field may further be associated with positioning-related information including at least one PRS configuration, at least one positioning measurement request, at least one location reporting request, or a combination thereof. The UE may perform the positioning-related action(s) based on the positioning-related information.
