    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: The invention concerns a method for precoding in an open loop transmission communications system. The method includes precoding data at each of M REs with a precoding matrix, precoding each of DM-RSs with one column of a precoding matrix which is same as that used for precoding M data REs. The method is distinguished by using at least L≧2 different precoding matrices from a set of precoding matrices W to precode the M REs and the E allocated REs such that REs precoded with a first precoding matrix are interleaved with REs precoded with at least one additional, different precoding matrix and the number of used precoding matrices L is adapted to the transmission rank r and number N of available DM-RS.

    Abstract: An apparatus for receiving non-orthogonal transmissions in a wireless communication system includes a processor configured to determine a first superposed symbol from a plurality of superposed symbols, based on superposition information and a first set of decoding information, wherein the first superposed symbol is corresponding to a first user equipment. The processor generates a residual signal based on the first superposed symbol and the superposition information, and determines a second superposed symbol based on the residual signal and a second set of decoding information, wherein the second superposed symbol is corresponding to a second user equipment. The superposition information comprises a quantity of the plurality of superposed symbols and an ordering of the plurality of superposed symbols.

    Abstract: The present invention relates to a method in a network control node for transmission of control channel signals in a wireless communication system, the wireless communication system employing scheduling of physical resource blocks (PRBs) used for each new transmission of a control channel signal, wherein each control channel signal is related to one or more control channel elements (CCEs); the method comprising the steps of: removing user specific reference signals in associated physical resource blocks (PRBs) if the associated physical resource blocks (PRBs) comprises at least one control channel signal; inserting control channel signals in the associated physical resource blocks (PRBs); and transmitting the associated physical resource blocks (PRBs). Furthermore, the invention also relates to a computer program, a computer program product, and a network control node device thereof.

    Abstract: A transmitter apparatus in a wireless communication system that includes a processor. In one embodiment, the processor is configured to receive at least one modulated data message and spread the at least one modulated data message into a transmission signal using a low density signature matrix. The low density signature matrix is a cycle-free signature matrix. A receiver apparatus is configured to receive the transmission signal and detect within the received transmission signal at least one modulated data message. The processor is configured to detect the at least one modulated data message in one iteration using the cycle-free signature matrix.
