Abstract: A first communication device and a second communication device for an iterative code design are provided. The first communication device generates and transmits sets of parity symbols and receives the transmitted sets of parity symbols from a second communication device. The sets of parity symbols are generated based on using a first generator device and based previously transmitted systematic symbols and computed noise values. The second communication device buffers received systematic symbols and sets of parity symbols and jointly decodes them. Thereby, an iterative code design is provided with improved performance. Furthermore, the disclosure also relates to corresponding methods and a computer program.

Abstract: A data transmission and signaling method in a transmitter device configured for concurrent transmission of non-orthogonal independent downlink data streams to receiver devices in a wireless communication system is provided. The method comprises sending to all receiver devices control information that includes indices of receiver devices selected for transmission, code rates of selected receiver devices, a label bit-to-receiver device allocation, an index of an expanded constellation, and a number of resource elements used for transmission.

Abstract: A transmitting device is provided. The transmitting device comprises a processor, and a transmitter; wherein the processor is configured to generate a fractional Orthogonal Frequency Division Multiplexing (OFDM) symbol based on an adjacent OFDM symbol, wherein the fractional OFDM symbol is a cyclic extension of the adjacent OFDM symbol; wherein the transmitter is configured to transmit a multicarrier signal comprising the fractional OFDM symbol and the adjacent OFDM symbol. Furthermore, the present invention also relates to a corresponding method, a multicarrier wireless communication system comprising such a transmitting device, a computer program, and a computer program product.

Abstract: A transmitting device and a receiving device are provided. The transmitting device comprises a signal processor configured to modulate bits representing control information for providing at least a first set of modulation symbols and a second set of modulation symbols, provide a first set of mapped modulation symbols by mapping the first set of modulation symbols onto a set of frequency resources within a first sub-band, and provide a second set of mapped modulation symbols by mapping the second set of modulation symbols onto a corresponding set of frequency resources within a second sub-band, wherein the first set of mapped modulation symbols and the second set of mapped modulation symbols differ from each other in at least one modulation symbol, and wherein the first sub-band and the second sub-band are non-overlapping.

Abstract: The present disclosure relates to a transmitter device and a receiver device. The transmitter device comprises a processor which is communicably coupled with a transmitter unit. The processor is configured to receive a set of Z data streams and select K data streams with the same channel quality from the set of Z data streams for transmission, where K≦Z. Thereafter for each information word and for each data stream k=0, . . . , K−1 the processor encodes, scrambles and superposes so as to obtain a first signal sU. Further, for each information word and for each data stream k=0, . . . , K−1 the processor interleaves, encodes, scrambles and superposes so as to obtain a second signal sV. The first signal sU and the second signal sV are combined by the processor into a single signal s for transmission. The transmitter unit of the transmitter device is configured to transmit the transmission signal s over a radio channel.
