摘要： In a radio communication system, a beam is formed between subscriber stations and a base station which has an antenna device with several antenna elements. The antenna elements emit a downlink signal based on respective weighing with coefficients of a weighting vector. A plurality of weighting vectors are determined at the subscriber station in an initialization phase and transmitted to the base station. In a subsequent working phase, the subscriber station selects a dominant weighting vector from the weighting vectors and transmits a designation of the selected weighting vector to the base station.

摘要： A method controls the downlink beam in a radio communication system. The radio communication system has an antenna system with several antenna elements. The method involves a) examining a received uplink signal sent by a transmitter for the existence of phase correlations between parts of the uplink signal received from various antenna elements of the antenna system, and b) if a phase correlation is detected, assigning at least one source direction to the uplink signal and sending the downlink signal in the source direction. If a phase correlation is not detected, however, the downlink signal is sent in a non-directional manner in the form of several components produced using at least one diversity technique.

摘要： 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.

摘要： The invention relates to a method for the transmission of a global pilot signal from a base station of a radio communication system to a user station and a base station suitable for carrying out the above method. The base station comprises a number of antennae each with a characteristic pilot bit sequence. The global pilot signal is generated by overlaying the pilot bit sequences emitted from the several antennae of the base station, whereby the following method steps are carried out: a) division of the several antennae into a first group and a second group each with at least one antenna, b) transmission of the pilot bit sequences of the antennae of just the first group and c) modification of the compositions of the first and second group and return to step b).

摘要： 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.

摘要： A method transmits signals of a link between a transmitting station and a receiving station of a radiocommunication system, wherein at least one pilot signal is transmitted between the stations NB and UE in order to enable estimation of at least one channel of said link by the receiving station. The channel estimation results are determined in order to detect data to be transmitted to the receiving station by means of the signals of the link. Deviation between the transmission characteristics of the pilot signal used for channel estimation and the transmission characteristics of the signals of the link is taken into account when the signals of the link which are to be transmitted are produces by the transmitting station and/or when the received signals of the link are processed by the receiving station.

摘要： A method forms polar diagrams in a connection between a subscriber and a base station with an antenna arrangement in a radio communications system using multiple access methods. Antenna signals are associated with polar diagrams of the antenna arrangement by a common beam forming network. The common beam forming network is used to form weighted sum signals, which are passed as input signals to a user-specific beam forming unit. A selector which is arranged there takes from the input signals a user-specific subset Kc of signals, to which an eigen polar diagram forming algorithm is applied.
