Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) receives a positioning reference signal (PRS) configuration indicating one or more PRS resources transmitted on one or more antenna ports of at least one antenna panel of a base station, measures the one or more PRS resources over a set of angles, wherein the UE is configured to search for the one or more PRS resources over the set of angles based on the PRS configuration, and determines an angle of the set of angles over which at least one PRS resource of the one or more PRS resources was measured as a downlink angle-of-departure (DL-AoD) between the base station and the UE.

Abstract: In an aspect, a user equipment (UE) may measure one or more positioning reference signals (PRS) transmitted by one or more transmission-reception-points (TRPs). The UE may measure one or more backscattered signals received from one or more ambient Internet-of-things (IoT) anchor devices, wherein the one or more backscattered signals correspond to the one or more PRS received at the one or more ambient IoT anchor devices.

Abstract: Techniques for line-of-sight (LOS) probability map signaling are disclosed. The techniques can include receiving a positioning signal via a wireless link between the UE and a transmission/reception point (TRP) of a radio access network (RAN), identifying an LOS probability function associated with the wireless link based on LOS probability map information provided by a location management function (LMF) of a core network for the RAN, and generating an LOS probability estimate for the wireless link using the LOS probability function.

Abstract: Disclosed are techniques for training a machine learning model. In an aspect, a user equipment (UE) receives, from a network entity, one or more selection criteria for determining whether the UE is to participate in training the machine learning model, determines whether the UE satisfies the one or more selection criteria during a first period of time, and transmits, to the network entity, after a second period of time, updated parameters for the machine learning model, wherein the machine learning model is updated during the second period of time based on a determination that the UE satisfies the one or more selection criteria.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a network entity receives a provide location information message from a user equipment (UE), the provide location information message including one or more positioning estimates derived by the UE during one or more positioning inference occasions of a machine learning model, wherein the machine learning model is applied to one or more measurements of a wireless channel between the UE and a network node during each of the one or more positioning inference occasions, and transmits a performance report indicating a performance of the machine learning model at least in deriving the one or more positioning estimates during the one or more positioning inference occasions.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a position estimation entity (e.g., UE, gNB, LMF, etc.) identifies a pool of UEs for a SL-assisted position estimation procedure of a set of target UEs. SL SRS-Ps are communicated (e.g., transmitted and measured) between the pool of UEs (e.g., for relative SL ranging). UL SRS-Ps are communicated by at least some of the UEs in the pool of UEs. The position estimation entity obtains measurement data for both the SL SRS-P and UL-SRS-P communications. The position estimation entity determines a position estimate for each UE in the set of UEs based on the measurement information.

Abstract: A method of requesting a reference signal includes sending, from a user equipment, a first on-demand reference signal (RS) request for an RS in response to a first positioning request; obtaining, at the user equipment, a first timer value indicative of a first threshold amount of time; sending, from the user equipment, a second on-demand RS request in response to either: the first threshold amount of time passing after sending the first on-demand RS request without at least one of receiving the RS at the user equipment or decoding an RS configuration message at the user equipment or receiving, at the user equipment, a second positioning request, having a higher priority than the first positioning request, before passage of the first threshold amount of time after sending the first on-demand RS request.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a position estimation entity, obtains first timing information that is associated with a first time-of-arrival (TOA) measurement of a first reference signal for positioning (RS-P) as communicated between a target user equipment (UE) and a base station with a first time basis, obtains second timing information that is associated with a second TOA measurement of a second RS-P as communicated between the target UE and a reference UE associated with a known location and having a second time basis that is different than the first time basis, determines a bias between the first time basis and the second time basis, and determines a position estimate of the target UE via a time differential of arrival (TDOA) positioning technique based at least in part upon the first timing information, the second timing information, and the bias.
