摘要:
The present invention provides a data transfer method for use in a CDMA system operating in the TDD mode. A data signal is transmitted in the form of a data stream of data bursts of different users between a first station and a second station via a multiplicity of antennas, and a reference signal is transmitted in connection with the specific data burst. In a first step, a reference signal is transmitted from the second station to the first station. In a second step, a channel estimation is performed in the first station based on the reference signal that is received from the second station. In a third step, the first station transmits a data burst to the second station via the multiplicity of antennas, it being possible to modify the transmission signals of various antennas having various amplitude and phase factors in accordance with the channel estimation.
摘要:
A method of operating a mobile wireless network ensures proper function of protocol entities during the transmission of data units between two wireless stations. User data is assembled by a first convergence protocol layer of the first wireless station into at least one first data unit, particularly a packet data unit, before transmission to a second convergence protocol layer of a second wireless station, particularly on the same protocol level, with the user data being supplied to the first convergence protocol layer by at least one user in a network layer. At least one protocol entity of the first convergence protocol layer is configured as a function of a configuration request received by the second wireless station, in order to form the at least one first data unit from the data received from the at least one user and to transmit it through a carrier to a link control layer.

A method of operating a mobile radio network for adjusting the counter states of the packet data units to be transmitted in the convergence protocol layer protocol units of network entities of the mobile radio network. User data is transmitted from a first network entity of the mobile radio network, in particular a mobile station, to a second network entity of the mobile radio network, in particular a higher-level network unit, the user data is combined prior to transmission into at least one packet data unit in a first convergence protocol layer protocol unit of the first network entity; and the at least one packet data unit is transmitted from a first radio link control layer protocol unit of the first network entity to a second radio link control layer protocol unit of the second network entity. If the transmission of the at least one packet data unit fails, the first radio link control layer protocol unit transmits an error message to the first convergence protocol layer protocol unit after receiving a confirmation message confirming the failure from the second radio link control layer protocol unit.

摘要:
A method of operating a mobile wireless network is provided, in which, when there is a relocation, the connection may be continued essentially directly from the latest state before the relocation. User data is transmitted between a mobile station and a first base station, the user data being combined into data units, for example, packet data units, before being transmitted. For transmission of data units, transmission-specific information describing an instantaneous state of the transmission is stored in the mobile station, as well as in a first network unit at a higher level than the first base station. With the relocation of the mobile station from the first base station to a second base station having a second higher-level network unit, the transmission-specific information stored in the first higher-level network unit is transmitted to the second higher-level network unit to continue the transmission after the relocation essentially directly from its latest state.

A method of assigning transmission channels in a telecommunications network and a user station are provided, which facilitate an increase in the capacity of a telecommunications network. The telecommunications network may include multiple base stations and mobile stations, the transmission channels being provided for transmitting signals between the base stations and the mobile stations. In uncoordinated operation of the base stations, at least one of the transmission channels is assigned for transmitting signals between one of the base stations and one of the mobile stations as a function of a channel measurement, in which the transmission power on all possible transmission channels is measured, if the previously measured transmission power on this transmission channel is minimal.

摘要:
A method of encrypting data, a telecommunications terminal and an access authorization card are described, which permit utilization of services of one or more service providers independently of a network operator or manufacturer of the telecommunications terminal. Encrypted data is transmitted between a service provider and the telecommunications terminal over a telecommunications network. Data to be transmitted over the telecommunications network is encrypted as a function of the service provider selected.
