Abstract:
A method for kinematic state estimation of a user equipment connected to a wireless communication network includes obtaining range rate measurement data defining a change rate of a distance between the user equipment and a range rate measuring position and obtaining range measurement data defining a distance between the user equipment and a range measuring position. A kinematic state estimation of the user equipment is performed based on at least the range rate measurement data and the range measurement data. The kinematic state estimation includes interacting-multiple-model filtering using three interacting models. The interacting-multiple-model filtering includes a three-dimensional constant velocity movement Wiener process, a three-dimensional constant acceleration movement Wiener process, and a three-dimensional constant position Wiener process.
