Реферат: A method for kinematic state estimation of a UE (10) in a wireless communication system (1). The method comprises estimating of a kinematic state comprising two-dimensional position, two-dimensional velocity (14) and a frequency bias of the UE (10). The estimation is based on and fully enabled by obtained measurements of Doppler shifts (22A; 22B), relative two different antennas of the wireless communication system (1), of radio signals (12) transmitted from the UE (10), and obtained distance-establishing measurements (R) associated with the UE (10). A network node performing the method and a computer program therefore are also presented.
