摘要:
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.

摘要:
In a method for communicating by radio, a frequency band divided up into a plurality of subcarriers is used for the communication. Messages are sent from a base station to a user station and/or from the user station to the base station. Messages are processed at some times using a first FDMA method such as for example OFDMA and at other times using a second FDMA method such as for example IFDMA. A transmitter and a receiver implement the method.

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.

A method and system are provided for monitoring adjacent cells in a mobile radio telephone system, in which a mobile station located in a cell of a mobile radio telephone system receives, for purposes of monitoring adjacent cells, transmits signals coded with different cell-specific codes from base stations of adjacent cells and codes and evaluates these in accordance with the respective cell-specific codes, wherein at least the base station currently responsible for the mobile station transmits a signaling information item which informs the mobile station of the codes to be used in the monitoring of adjacent cells and/or of the codes not to be used in monitoring adjacent cells, and the mobile station, in monitoring adjacent cells, only decodes and evaluates the transmit signals of the adjacent cells coded with a code which can be used for the monitoring of adjacent cells in accordance with the signaling information.
摘要:
It is described a method for changing the data load distribution within a telecommunication network including a first base station, a second base station and a relay node being connected to the first base station and/or to the second base station. The described method includes (a) establishing for each of a plurality of user equipments a first indirect connection to the first base station via the relay node, (b) establishing in a collective manner for each of the plurality of user equipments a second indirect connection to the second base station via the relay node, and (c) terminating in a collective manner for each of the plurality of user equipments the first indirect connection. It is further described a network element, which is adapted to carry out the above described data load redistribution method, and a computer program, which is adapted for controlling the above described data load redistribution method.
摘要:
It is provided a method for adapting a parameter being indicative for a trigger signal for starting measurements, by a first base station of a first radio access network of a first type of radio access technology, of a signal quality of signals being received from a second base station of a second radio access network of a second type of radio access technology. The method includes measuring by a user equipment, which is served by the second base station, the signal quality of signals being received from the first base station, reporting a signal being indicative for the measured signal quality from the user equipment to a network entity, and adapting, by the network entity, a parameter based on the measured signal quality, wherein the parameter is indicative for a trigger signal for starting measuring a further signal quality of signals being received from the second base station.
摘要:
It is disclosed a method including creating inquiry information related to an evaluation of at least one network terminal, and transmitting the created inquiry information in a long-range reference signal; a method including receiving the inquiry information in the long-range signal, establishing, based on the received inquiry information, report information related to a quality of the long-range reference signal, and transmitting the established report information; and a method including receiving the report information, and evaluating, based on the received report information, at least one network terminal.
摘要:
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.
