  • Patent number: 8611914
    Abstract: According to a method for operating a radio communication system, a first radio station decides about the assignment of first radio resources to a user terminal and thereafter assigns the first radio resources to the user terminal. Before deciding about the assignment of the first radio resources to the user terminal, the first radio station transmits information to a second radio station regarding the first radio station's future assignment of the first radio resources. Radio stations carry out the method.

  • Patent number: 8588089
    Abstract: A mechanism for controlling resources and/or settings of an access network element like a base station is provided which allows an autonomous reconfiguration of, for example, the antenna configuration based on a set of performance indicators in a base station. The base station can reconfigure itself without the need of operator control so that during periods with low capacity demands the base station will reconfigure correspondingly, which may include a reduction of active cells by turning off the power for a part of the installed equipment.

  • Publication number: 20090239569
    Abstract: A method for changing a downlink transmission power level can include receiving information about interference noise. When the interference noise satisfied a predefined level, the downlink transmission power level can be changed. Typically, the transmission power level can be decreased when the interference noise is above a predefined value. The transmission power level change can be coordinated (e.g. coordination in terms of power step size, in terms of frequency portion to which the power change is applied and in terms of time when to apply the transmission power change) with transmission power level changes in other cells. Also, interferences levels may be reassessed following the first transmission power change and the power levels are changes a second time. Optionally, only a portion of the transmission bandwidth is changed or only specific DL physical channels are considered.

  • Patent number: 7415249
    Abstract: The present invention seeks to estimate a dedicated channel of the downlink transmission from a base station (BS) to a subscriber station (MS) in a mobile radio communications system with antenna diversity. To this end, the subscriber station (MS) calculates a first estimation of the dedicated channel from an estimation of a global channel (CPICH) while using a weighting vector (W, W?) used by the base station (BS) for the beam forming of the dedicated channel.

  • Patent number: 7142584
    Abstract: A method for synchronizing a base station to a mobile station includes transmitting a signal sequence K(i) of length n from the base station to the mobile station. The signal sequence K(i) is formed by repeating a second signal sequence element K2(k) of length n2 n1 times. The second signal sequence is modulated with a first signal sequence element K1(j) of length n1. In the method, n1 is equal to n2 and i, j and k are integers.

  • Patent number: 7089039
    Abstract: A method is provided for beam shaping in a radio communication system having subscriber stations and a base station, and an antenna device with a number of antenna elements that emit a downlink signal weighted with a coefficient of an actual weighting vector to a subscriber station, the actual weighting vector being updated via feedback information from the subscriber station. The subscriber station estimates the direction of a control vector in an M-dimensional vector space using measurements of the downlink signals, it detects a deviation of the estimated direction from the direction of a reference control vector and transmits information representative of the deviation to the base station. The base station then adapts the weighting vector using the representative information.

  • Patent number: 7050833
    Abstract: A method is provided for controlling the beam formation of downlink signals, which are emitted in a mobile radio communications system by base stations of a first and a second radio cell to a mobile station, whereby the base stations are configured to emit a weighted downlink signal to the mobile station, using a weighting vector. The method includes the steps of determination of a weighting vector record in the mobile station and the base stations of the first and second radio cell; selection of an optimal weighting vector in the mobile station and transmission of a code word that is assigned to the optimal weighting vector to the base stations; and weighted emission of the downlink signal to each base station using the weighted vector that has been assigned to the code word. In the base stations, the weighting vectors are assigned to the code words in various ways, so that upon receipt of an identical code word, the base stations weight the downlink signal using different weighting vectors.
