Abstract: Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) receives, from a network entity, a positioning reference signal (PRS) configuration indicating one or more PRS resources. The UE determines that one or more transmission properties of the one or more resources should be modified and transmits PRS modification information to the network entity based on the one or more transmission properties of one or more PRS resources to be modified. The network entity may be a location server or location management function. The PRS modification information may include a request to modify the PRS configuration and information indicating a start time, a stop time, a duration, or a combination thereof, associated with modifying the PRS configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus may obtain a set of training measurement information associated with a user equipment (UE). The apparatus may obtain a training position value associated with the UE. The apparatus may provide the training position value and the set of training measurement information for training of a model using a machine learning (ML) technique, the model being trained to output location information based at least in part on measurement information. Numerous other aspects are described.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives, from a network entity, beam shape assistance information for one or more downlink transmit beams of a base station, the beam shape assistance information representing a beam shape of each of the one or more downlink transmit beams, the beam shape of each of the one or more downlink transmit beams having a quantization, and determines an angle between the UE and the base station based at least on the beam shape assistance information and signal strength measurements of positioning reference signal resources transmitted on the one or more downlink transmit beams.

Abstract: Disclosed are systems, methods, and non-transitory media for improving user equipment (UE) positioning. In some aspects, UE positioning improvements are facilitated by a location server, such as a Location Management Function (LMF) that receives location measurements from the UE and transmits back a feedback messaging, that can be used to modify transmission of subsequent location measurements to the location server.

Abstract: In some implementations, an example method of wireless communication at a base station for wireless positioning a user equipment (UE) may comprise: transmitting, to a different device, assistance indicating a location of antenna reference points (ARPs) of the base station for a first set of TRPs configured for receiving uplink (UL) sounding reference signals (SRSs) different from a location of antenna reference points (ARPs) of the base station for a second set of TRPs configured for transmitting downlink (DL) position reference signals (PRSs). The method also comprises performing a measurement of a UL reference signal received by the first set of TRPs. And the method further comprises transmitting the measurement to the different device.

Abstract: In an aspect, a UE may transmit one or more reference signals. The UE may obtain one or more self-radio frequency fingerprint (self-RFFP) measurements based on reflections of the one or more reference signals transmitted by the UE. The UE may determine a location of the UE based on applying a machine learning model to the one or more self-RFFP measurements.

Abstract: Information inherently conveyed in the hierarchical structure of a positioning frequency layer is leveraged to determine a sequence identifier unique to each Positioning Reference Signal (PRS) resource of a sequence of PRS resources used in a positioning session of a user equipment (UE). This unique sequence number can then be used in the reporting of measurement data by the UE or other reporting device to a location server. As such, embodiments herein effectively provide means for compressing identification information included in position measurement reporting to the location server.
