  • Patent number: 8213757
    Abstract: The present invention relates to a display and antenna arrangement comprising a primary display screen (30) and an antenna arrangement comprising a number of receiving and/or transmitting elements (1A11, 1A12,1A13) formed by an least in given areas electrically conductive layer and adapted to receive/transmit radio-, millimeter waves or microwaves. The electrically conductive layer is perforated and comprises a plurality of densely arranged holes (4m, . . . ) crossing the layer. Said holes (4111, . . . ) contain a dielectric material. The perforated conductive layer is provided on the front of the primary display screen, said holes being adapted to guide light/optical information from the primary display screen through the electrically conductive layer, the outer surface of which facing away from the primary display screen.

  • Publication number: 20120155422
    Abstract: Mobility-based radio resource assignment methods, systems and devices can assign user equipment to different nonoverlapping groups of radio resources depending on mobility of the user equipment. The groups of radio resources are nonoverlapping in time, frequency and/or code. For example, the groups of radio resources can include different pilot symbol densities, link adaptation and/or scheduling algorithms. The radio resources may be Long Term Evolution (LTE) radio resources.

  • Patent number: 8179320
    Abstract: The present invention relates to a method and devices for determining the position of a user equipment in a mobile radio communications system. According to the invention, the position is determined via a distortion in a radio signal transmitted to or from the user equipment, wherein the distortion is caused by a scatterer being positioned at a particular location and having time-dependent scattering properties such that the scattering of a radio signal gives rise to a distortion by which said scattering properties may be identified.

  • Publication number: 20100190456
    Abstract: The present invention relates to a method for adapting transmission parameters in a transmitter Tx in communication with at least one antenna 27; 38; 47; 57; 77, 88. The method comprises: transmitting a signal from the transmitter Tx measuring at least one reflection coefficient S11 of said signal for each antenna 27; 38; 47; 57; 77, 88, and adapting the transmission parameters based on the measured reflection coefficient S11. The antenna could be a transmit antenna and/or a receive antenna. In a preferred embodiment antenna calibration may be performed by measuring propagation time for each individual transmitter chain 481, 482; 781, 782, and compensate for differences in time delay between the individual transmitter chains 481, 482; 781, 782 to assure that the signal is transmitted simultaneously from all transmit antennas.
