Patent number: 7239848Abstract: A telecommunication system is described for transmitting signals between an adaptive antenna of a base station and a mobile user equipment. At least one uplink parameter of a signal received by the base station is calculated. The uplink parameter relates to a specific location of the mobile user equipment. At least one downlink parameter of a signal sent by the base station is evaluated. Said downlink parameter relates to the same specific location of the mobile user equipment. Said uplink parameter and said corresponding downlink parameter are stored in the base station.Type: GrantFiled: December 2, 2002Date of Patent: July 3, 2007Assignee: AlcatelInventor: Ivar Mortensen

Patent number: 6594321Abstract: A method is described of generating an electrical output signal (CFCS) from an electrical input signal (CS) wherein the input signal (CS) is first clipped (12) and then filtered (13) into the output signal (CFCS). The invention is characterized in that the input signal (CS) is clipped dependant on the succeeding filtering. Thereby, a finite power peak capacity of a succeeding amplifier is not exceeded.Type: GrantFiled: July 19, 1999Date of Patent: July 15, 2003Assignee: AlcatelInventor: Ivar Mortensen

Patent number: 6591113Abstract: A method of operating a cellular telecommunication system is described, wherein one base station communicates with at least one mobile station, and wherein the power level of the transmission is increased and decreased by requests of the mobile station. The transmission includes at least two channels (DPDCH, DPCCH), e.g data and control. One of the two channels (DPDCH) is turned off if the power level of the transmission reaches a first maximum value (DPDCH-MAX).Type: GrantFiled: October 27, 2000Date of Patent: July 8, 2003Assignee: AlcatelInventor: Ivar Mortensen

Publication number: 20020145994Abstract: A method is described for operating a radio-based telecommunications system, in particular a UMTS telecommunications system. The data to be transmitted are transmitted in data frames, so-called frames. A plurality of frames are combined to form a group. A format-related indicator is transmitted for each frame. A number of permissible format-related indicators is specified in advance. The number of permissible format-related indicators is reduced as a function of the combination of frames in groups.Type: ApplicationFiled: March 28, 2002Publication date: October 10, 2002Applicant: ALCATELInventor: Ivar Mortensen

Patent number: 6389265Abstract: In a UMTS (Universal Mobile Telecommunications System) wherein multiple base stations are able to communicate simultaneously with the same mobile station, with forward direction power control where the mobile station sends a transmit power control command to all base stations serving it, a “feedback-type transmit power correction” is implemented wherein information (PL1, PL2) is transmitted about the current transmitted powers from the base stations (NB1, NB2) to a base station controller (SRNC) which evaluates this information to calculate a correction value (CV1) for the power transmitted by at least one (NB1) of the base stations, which then additionally changes its transmitted power by this correction value (CV1).Type: GrantFiled: May 24, 1999Date of Patent: May 14, 2002Assignee: AlcatelInventors: Michael Jeschke, Ivar Mortensen

Patent number: 5740202Abstract: The method makes it possible digitally to evaluate the phase of any carrier that has been subjected to rPSK modulation subsequent to clock recovery, sampling, and digitizing the in-phase and quadrature components of the samples, by processing that is performed in polar coordinates and that comprises reducing the range over which the phase of each sample is defined to a range of +.pi./r to -.pi./r and then seeking the center of gravity over 2.sup.N successive samples (N being an integer) by performing successive averaging calculations, each time on two values, in application of an N-stage tree structure. Each average of two values is associated with an index indicative of the degree of reliability of the average, and those averages which are associated with a small reliability index are ignored while calculating subsequent averages in the tree structure.Type: GrantFiled: September 22, 1995Date of Patent: April 14, 1998Assignee: France TelecomInventors: Ivar Mortensen, Marie-Laure Boucheret, Henri Favaro, Eric Belis
