  • Patent number: 9578464
    Abstract: The invention is directed to systems, methods and computer program products for determining a location of a device on a massive MIMO (multiple-input multiple-output) network. The device transmits a signal comprising several multipath components (MPCs) either omnidirectionally or with limited directivity. The method comprising identifying, by a base station, that receives MPCs, an MPC with a figure of merit, based on a time delay and an angular spread, better than that of other MPCs; determining, by the base station, an angle of arrival (AoA) of the MPC is different from the AoAs of the other MPCs; and determining, by the base station, a location of the device based on the time delay and the AoA.

  • Publication number: 20170045627
    Abstract: The present invention relates to a method for determining a relative position between a first device and a second device. A plurality of measurement signals is transmitted from the first device to the second device. Each measurement signal of the plurality of measurement signals is associated with a corresponding radio frequency spectrum in which the measurement signal is transmitted. A first radio frequency spectrum associated with a first measurement signal has a different frequency range than a second radio frequency spectrum associated with a second measurement signal of the plurality of measurement signals. At the second device the relative position based on at least the first and second measurement signals is determined.
