The present disclosure relates to methods and apparatuses for improving positioning of a device in a wireless communications network. In some embodiments, a method performed by a measuring device configured to communicate with a positioning device, comprises: determining a cross-correlation between a received signal and a transmitted reference signal; determining a channel impulse response (CIR) of the cross-correlation related to a first lobe detected above a selected threshold in said CIR; and reporting information on a truncated part of the CIR around the first lobe to the positioning device for enabling the positioning device to correct or estimate a measurement related to a distance between a transmitter and the measuring device and/or a distance between at least one reflecting cluster and the measuring device.

Methods and apparatuses for positioning in a wireless communications network

In a method for the continuous real time tracking of the position of at least one mobile object in a defined multidimensional space, at least one mobile transmitter module is attached to at least one mobile object and the signals from the at least one module are received by a stationary receiving and signal processing network and then centrally processed. The signals emitted by each transmitter module are electromagnetic waves sent within a frequency band range using time division multiplexing techniques. Due to the fact that the frequency band is used as a single channel for the purpose of maximizing the accuracy with which a position is detected, and due also to the fact that the communication process between the transmitters and the receivers is based on the principle of pseudo-random time division multiplexing using burst transmissions of low cross correlation with non synchronized pseudo-random patterns, there is created a method for the continuous tracking of the position of one or more mobile objects at any time and in any place which is of very high positional resolution and has a temporal resolution of just a few milliseconds.
