USER EQUIPMENT TWO-DIMENSIONAL STATE ESTIMATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17919665 titled 'USER EQUIPMENT TWO-DIMENSIONAL STATE ESTIMATION

Simplified Explanation

The patent application describes a method for estimating the kinematic state of a User Equipment (UE) in a wireless communication system. This includes determining the position, velocity, and frequency bias of the UE.

  • The method relies on measurements of Doppler shifts and relative distances between different antennas in the wireless communication system.
  • These measurements are used to estimate the kinematic state of the UE, which includes its two-dimensional position and velocity.
  • The method also takes into account the frequency bias of the UE, which can affect the accuracy of the estimation.
  • The estimation process is fully enabled by the obtained measurements of Doppler shifts and distance-establishing measurements associated with the UE.
  • The patent application also includes a network node that performs the method and a computer program for implementing the method.


Original Abstract Submitted

A method for kinematic state estimation of a UE in a wireless communication system. The method includes estimating of a kinematic state having two-dimensional position, two-dimensional velocity and a frequency bias of the UE. The estimation is based on and fully enabled by obtained measurements of Doppler shifts, relative two different antennas of the wireless communication system, of radio signals transmitted from the UE, and obtained distance-establishing measurements associated with the UE. A network node performing the method and a computer program therefore are also presented.
