Abstract: Improved techniques of reducing latency in UL positioning include generating a priority indication by the LMF for all UE requiring UL positioning. For example, an LMF can generate a priority list identifying UEs within a network that may be considered by a serving network node (gNB) for positioning prioritization. In some implementations, the serving gNB indicates that prioritizing all of the identified UEs would require more network resources than are available. In such a case, the LMF obtains latency measurement values for TRPs in the network. Based on the latency measurement values obtained, the LMF performs a configuration operation on at least one of the TRPs to reduce the UL positioning latency to an acceptable value.

Abstract: An apparatus comprising circuitry configured to: receive a plurality of signal samples, wherein at least two of the signal samples are received on different carrier frequencies or over different durations; convert the plurality of signal samples to a common data format that stores as entries the samples, a stored entry corresponding to a sample measured with a carrier frequency, a time, and a receive antenna; generate entries of the common data format that are missing due to a sample not being measured with a carrier frequency, time, and receive antenna; wherein the entries of the common data format are ranked, wherein a higher ranking entry is considered more relevant than a relatively lower ranking entry; and generate at least one positioning measurement with a machine learning model, based on the entries of the common data format and the ranking of the entries of the common data format.
