  • Temporal analysis for user speed estimation in wireless networks
    Patent number: 10901076
    Abstract: A method for estimating the speed of a user equipment connected to a base station of a wireless network, the method comprising the following steps: measuring the power of a signal transmitted between the user equipment and the base station; computing the derivative of the measured signal power with respect to time; computing the standard deviation of the computed derivative; estimating, from previously established reference data, the speed of the user equipment that corresponds to the computed standard deviation, the reference data associating a given user equipment speed with a certain computed standard deviation.
    Type: Grant

    Date of Patent: January 26, 2021
    Assignee: Alcatel Lucent; INRIA
    Inventors: Nidham Ben Rached, Veronique Capdevielle, Majed Haddad, Frédéric Ratovelomanana, Afef Feki, Eitan Altman
  • Method and system for user speed estimation in wireless networks
    Patent number: 9673922
    Abstract: A method for estimating the speed of a user equipment connected to a base station of a wireless network, the method comprising the following steps: —performing signal strength measurements (S) of a radio signal transmitted between the user equipment and the base station; —performing a spectral analysis (11) of the signal strength measurements; —determining the frequency of a local maximum in the power spectrum of the signal strength measurements; —estimating (12), from previously established reference data, the speed of the user equipment that corresponds to the determined frequency, the reference data associating a given user equipment speed with a certain determined frequency.
