Title:
METHODS AND APPARATUS FOR TERMINAL-ASSISTED IMPROVEMENT OF TIMING-BASED POSITIONING ACCURACY
Document Type and Number:
WIPO Patent Application WO/2013/093887
Kind Code:
A3
Abstract:
There are provided measures for enabling a terminal-assisted improvement of timing-based positioning accuracy. Such measures may exemplarily comprise measuring a cell-related timing value for timing-based positioning calculation on the basis of a cell-originated positioning-related signal and measuring a terminal-related timing value for timing-based positioning calculation at an apparatus to be positioned, and utilizing the measured cell-related timing value and the measured terminal-related timing value for timing-based positioning calculation relating to the apparatus to be positioned at a network side.
