  • Apparatus and method for switching from reception to transmission
    Patent number: 8989677
    Abstract: The invention is related to an apparatus comprising: at least one definition unit configured to define signal characterizing parameters of a transmission; and at least one routing unit configured to route the transmission to at least one transmission path based on the signal characterizing parameters, the at least one transmission path arranged to convey the transmission to at least one antenna.
    Type: Grant

    Date of Patent: March 24, 2015
    Assignee: Nokia Corporation
    Inventors: Marko Eero Tapani Leinonen, Seppo Olavi Rousu, Juha Pentti Tapio Valtanen
  • Method and Apparatus for Controlling Parameters of an Antenna Tuner
    Publication number: 20140357200
    Abstract: The present invention discloses a control method, an apparatus and a computer program for antenna tuner parameters of a radio transceiver. The updating moments of the antenna tuner parameters are selected depending on predominant interference status in the receiver. Based on the sensed interference level, an update decision is made whether the external interference is below a selected threshold value. The parameter change is executed only in low interference situations. In high interference levels (low SIR), the antenna tuner parameters are calculated but they are not enforced in the antenna tuner. The control process for updating the antenna tuner parameters is continuous in given time intervals.

  • Qualify method for shielding of transceiver RF block
    Patent number: 8086185
    Abstract: A method is provided for inputting a signal that is modulated at a predetermined frequency to a receiver signal path of a radio subsystem and demodulating the signal at the predetermined frequency as it passes through the receiver signal path, measuring signal quality of the demodulated signal, and quantitatively assessing shielding of the radio subsystem with the measured signal.
