Abstract: Techniques described herein provide means by which cell information indicative of a location of a UE may be conveyed to a location server over a 5G NR data connection using a SUPL message with an LTE cell ID data field. In some embodiments, for example, the UE may include the Cell ID of a LTE neighbor cell or information regarding a 5G NR serving cell, such as a portion of the 5G NR Cell ID or a reserved value or sequence identifying the 5G NR serving cell. The techniques may be applicable to the Secure User Plane Location (SUPL) solution defined by OMA and may enable a UE and a SUPL Location Platform (SLP) to support location of the UE using a version of SUPL without explicit support of 5G NR wireless access.

Abstract: A computer system is provided that is programmed to select feature sets from a large number of features. Features for a set are selected based on metagradient information returned from a machine learning process that has been performed on an earlier selected feature set. The process can iterate until a selected feature set converges or otherwise meets or exceeds a given threshold.
