Title:
マルチビームユーザ機器ベースの測位シナリオにおける測位参照信号（ＰＲＳ）リソースについてのロケーション支援情報の階層型報告
Document Type and Number:
Japanese Patent JP7483860
Kind Code:
B2
Abstract:
Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) performs LTE-based positioning. The UE receives assistance data for enabling the UE to estimate a location of the UE, the assistance data including a relative location of each of a plurality of transmission points, wherein the relative location is represented as a hierarchy of two or more levels of description, wherein a highest level of description is relative to a fixed reference point, a first level of description of the hierarchy of the two or more levels of description representing the relative location of the transmission point represents a location of a transmission-reception point relative to the fixed reference point, and a second level of description of the hierarchy of the two or more levels of description representing the relative location of the transmission point represents a location corresponding to a positioning reference signal resource set relative to the location corresponding to the transmission-reception point, receives, from each of at least a subset of the plurality of transmission points, at least one positioning reference signal, and estimates the location of the UE based on characteristics of reception of the at least one positioning reference signal from each of the subset of the plurality of transmission points and the two or more levels of description and the fixed reference point for each of the subset of the plurality of transmission points.
