Abstract: In an orthogonal multicarrier radio transmission system complex-valued symbols are transmitted, wherein the real part and the imaginary part of each symbol are shifted against each other by one half symbol period and wherein a non-symmetric conjugate-root filter is applied to each symbol before transmission to mitigate inter-carrier interference and intersymbol interference. Corresponding reverse steps are performed at the receiver.

Abstract: In a cellular communication system a radio terminal registers a network based service, e.g. a Communication Waiting supplementary service. By transmitting a register request comprising a corresponding option tag, the radio terminal explores whether the network supports the requested network based service. In that case a user profile associated with the requesting radio terminal is updated and the radio terminal may henceforth use that service.

Abstract: In a multicarrier radio transmission system complex-valued symbols are assigned to at least a first subcarrier and a second adjacent subcarrier, wherein the symbols assigned to the second subcarrier are offset in frequency by half a subcarrier against the symbols assigned to the first subcarrier.

Abstract: A cellular telecommunication system comprising at least two communicatively coupled radio transmitter stations is described, wherein the stations are communicatively coupled via a backhaul link. Each base station is capable of beamforming, i.e. controlling the propagation direction of a transmitted radio signal. The radio base stations mutually exchange information regarding the beamforming in order to iteratively optimize the system performance (e.g. throughput, fairness, etc.).

Abstract: A transmission method and corresponding mobile communication system are described. A mobile terminal transmits information via an access channel to a base station that quantizes the received symbols and forwards these via a forward path to a central baseband unit. In the central baseband unit soft information relating to the transmitted information is determined based on received forwarded symbols, a quantizer codebook and the deployed mapping of the mobile terminal. Said soft information may serve as a basis for decoding the information.

Abstract: A radio transmission system based on a frequency divisional multiplexing method is described, comprising an improved method for estimating symbol timing offset and frequency timing offset. The receiver estimates the symbol timing offset based of a block of received symbols based on a cyclic prefix and suffix.

Abstract: Method for providing an identity identifier of an electronic terminal device. According to the method, via an interface, the electronic device receives a request from the party to provide an identity identifier, which has at least a request identifier. Via a communication link between the electronic terminal device and a server device assigned to the first communication network, a key to encode an identity identifier assigned to the electronic terminal device is transmitted from the server device to the electronic terminal device. By means of the key, at least the identity identifier in the electronic terminal device is encoded. The at least encoded identity identifier is linked to the request identifier received in the electronic terminal device, transmitted from the electronic terminal device to the server device, and decoded in the server device. The decoded identity identifier, together with the linked request identifier, is provided for transmission to the party.

Abstract: Method and system of performing a money transfer over a network or between accounts within a given monetary account system, wherein on the occurrence of a trigger event a money transfer is effected from a first SVA entity, which serves as a loaning entity, to a second SVA entity, which serves as a receiving entity. In order to provide a solution by which a loaner of money and a receiver of money can be brought into a special relationship such that it is particularly possible to automatically performing a money transfer it is provided that on the occurrence of the trigger event the money transfer is effected from the first SVA loaning entity to such a second SVA receiving entity, that has been set up in a previous authorisation step as a pre-authorised second SVA receiving entity with respect to the first SVA loaning entity.
