Abstract: Aspects presented herein may enable a network entity to calculate a relative clock drift between a Tx antenna panel and an Rx antenna panel that use different RF hardware/circuits (e.g., clocks). In one aspect, a network entity obtains a plurality of RTT measurements between a Tx antenna panel, a device with a known position, and an Rx antenna panel over a period of time, where the Tx antenna panel is associated with a first clock and the Rx antenna panel is associated with a second clock. The network entity obtains a first timing delay associated with the device based on the plurality of RTT measurements. The network entity calculates a clock offset between the Tx antenna panel and the Rx antenna panel based on the obtained first timing delay associated with the device.

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 UE-based wireless positioning. In an aspect, a user equipment (UE) may acquire, from a first set of transmission/reception entities (TREs), a first set of measurements of signals. The UE may select, from the first set of TREs, a second set of TREs, based on criteria for selecting and/or prioritizing TREs for radio frequency fingerprint (RFFP)-based positioning. The UE may acquire, from the second set of TREs, a second set of measurements, the second set of measurements comprising RFFP measurements. The UE may estimate a position of the UE based on the second set of measurements. In an aspect, the UE may input the second set of measurements into a trained machine learning (ML) model that outputs an estimated position of the UE. In an aspect, the UE receives the selection/prioritization criteria and/or the trained ML model from a network node.

Abstract: In an embodiment, a serving BS of a UE may transmit a PDCCH communication to the UE. The PDCCH communication triggers a partial RACH procedure, whereby a RACH transmission is performed. In some designs, the RACH transmission is for positioning, and positioning measurements are performed at the serving BS and (optionally) at one or more non-serving BSs. In some designs, measurement data based on the positioning measurements are conveyed to a position estimation entity (e.g., LMF), which performs a positioning estimate of the UE.
