Publication number: 20240129781Abstract: Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) identifies a set of positioning sources, each positioning source comprising a positioning reference signal (PRS) resource, a PRS resource set, a PRS frequency layer, and/or a transmission/reception point (TRP). From the set of positioning sources, the UE identifies a consistency group comprising a collection of positioning sources grouped based on expected values of at least one metric of a reference signal from each positioning source, measured values of the at least one metric for the reference signal from each positioning source, and an error threshold. The UE identifies one or more subsets of positioning sources within the consistency group, each subset having at least one metric error value. The UE reports, to a network entity, information about the consistency group and information about at least one of the subsets of positioning sources within the consistency group.Type: ApplicationFiled: December 7, 2023Publication date: April 18, 2024Inventors: Alexandros MANOLAKOS, Sony AKKARAKARAN, Jingchao BAO, Weimin DUAN, Tao LUO, Juan MONTOJO

Reporting of combined measurement associated with multiple samples for a position estimation session
Patent number: 11960014Abstract: Disclosed are techniques for communication. In an aspect, a UE reports a combination pattern for a combined measurement associated with samples across PRS occasions of a PRS measurement procedure. In another aspect, a UE reports a combined calibration error of a combined measurement associated with samples across PRS occasions of a PRS measurement procedure. The reported combination pattern and/or combined calibration error may be used by a position estimation entity for derivation of a position estimate of the UE.Type: GrantFiled: October 14, 2021Date of Patent: April 16, 2024Assignee: QUALCOMM IncorporatedInventors: Jingchao Bao, Sony Akkarakaran, Weimin Duan -
Publication number: 20240080149Abstract: Techniques for indicating a type of non-line-of-sight (NLOS) wireless signal path in a wireless communication network are described. In some embodiments, a method thereof may include receiving a plurality of reference signals, the plurality of reference signals originating from a respective plurality of wireless network nodes; determining at least one NLOS wireless signal path based on the plurality of reference signals; determining whether or not the at least one NLOS wireless signal path is introduced by a repeater of the wireless communication network based at least on a presence or an absence of a commonality among the plurality of reference signals; and indicating to a network entity whether the at least one NLOS wireless signal path is introduced by the repeater or not.Type: ApplicationFiled: September 2, 2022Publication date: March 7, 2024Inventors: Weimin DUAN, Jingchao BAO, Hyojin LEE

Publication number: 20240077568Abstract: Techniques for detecting non-line-of-sight (NLOS) wireless signal paths are described. In some embodiments, a method thereof may include receiving positioning information from one or more networked devices, the positioning information comprising information indicative of measurements of one or more wireless signals transmitted between one or more wireless network nodes and one or more UEs, location data indicative of a location of each of the one or more UEs, or a combination thereof; determining a commonality associated with the received positioning information; and based on the determined commonality, determining that the NLOS wireless signal path is present between the given UE and the one or more wireless network nodes.Type: ApplicationFiled: September 2, 2022Publication date: March 7, 2024Inventors: Weimin DUAN, Jingchao BAO, Hyojin LEE

Publication number: 20240068069Abstract: Copper-tin-nickel brazing material prepared by alloys recycled from E-waste, preparation method therefor, and system thereof are provided. A preparation method for the copper-tin-nickel brazing material includes the following steps: (a) spreading nano-SiO2 on the bottom of crucible and then adding a crude copper-tin-iron-nickel alloy recycled from E-waste; (b) heating the crucible to melt the crude alloy into a metal liquid so that Zn and Pb in the metal liquid react with the SiO2 to form a slag that floats out; (c) introducing a refining gas to the bottom of metal liquid in step (b), thereby removing the scums or gases formed by Pb, Fe, S, and O in the metal liquid; (d) performing heat-preserving directional solidification on the metal liquid, to bias-aggregate the Fe and Sb at one end and remove the same to obtain a copper-based intermediate alloy; and smelting and powdering the copper-based intermediate alloy.Type: ApplicationFiled: August 29, 2023Publication date: February 29, 2024Inventors: Weimin LONG, Tianran DING, Sujuan ZHONG, Li BAO, Junlan HUANG, Jiao YANG, Yuanyuan DONG, Hangyan XUE, Yanhong GUO
