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: A network node supports position measurement determination for a user equipment (UE) by prioritizing positioning reference signal (PRS) resource measurements to be included in a location information report based on multipath characteristics of the PRS resources. The network node, for example, may be the UE, a base station, or a sidelink UE.

The multipath characteristics of each PRS resource may be the number, a strength metric, or a time domain span of the multipath components, or any combination thereof. A location server may request the prioritization of the PRS resource measurements based on the multipath characteristics of the PRS resources and may use the order of the PRS resource measurements in the position determination for the UE.
