摘要:
In a method and/or an OFDM device for SC-FDMA data transmission, a sequence of input data is transformed by means of a discrete transformation as transformed data signals of coded and modulated data signals on first frequency channels into a first frequency space over a first number of frequencies. The transformed data signals are mapped on second frequency channels in a second frequency space with a larger second number of frequencies. The transformed data signals on the second frequency channels are inverse-transformed using an inverse transformation. Data inversely transformed in such a way are provided for transmission. The transformed data signals are mapped into a frequency range of the second frequency channels in such a way that a constant component of the transformed data signals is mapped centrally within the frequency range.

A method processes information to be sent via radio, according to which first bits represent a first number of N-tuples and second bits represent a second number of N-tuples. The first bits are to be sent using a first group of sub-bands of a frequency band, and the second bits are to be sent using a second group of sub-bands of the frequency band. A first modulation method is used for the first bits and a second modulation method is used for the second bits. The first bits are rearranged, forming M-tuples, and a symbol is formed from each M-tuple according to the first modulation method. The second bits are rearranged, forming P-tuples, and a symbol is formed from each P-tuple according to the second modulation method, and M≠P. A corresponding method is used for processing information received by radio. Base stations and mobile radio stations carry out the method.

Signals having an antenna-individual training sequence are transmitted from at least two transmitting antennas in a transmitting station of a communications system. The training sequences are formed in such a manner that the respective transmitting antenna can be identified on the receiving side based on the training sequence.

A method detects a first baseband signal sent by a first sending station via an air interface to a first radio station of a radio communications system. A first receive signal, which contains the first baseband signal superposed with at least a second baseband signal sent by a second sending station to a second radio station, is received by the first radio station. The first radio station uses at least a second receive signal received by the second radio station for detection of the first baseband signal. The second receive signal contains at least the second baseband signal, and is used to at least partially cancel the interference in the first receive signal caused by the second baseband signal.

A user equipment obtains channel state information for base stations serving the user equipment according to a coordinated multi-point transmission, arranges the channel state information in a predetermined order, and transmits the channel state information in the predetermined order. At least one base station of the base stations receives the channel state information, arranges the channel state information in the predetermined order into a datagram, and transmits the datagram to at least one other base station of the base stations.
