Abstract: A transmitting device is described for a communication system. The transmitting device obtains an information message comprising information bits addressed for a receiving device and encodes the information message to obtain a codeword. The transmitting device rate-matches the codeword to produce a rate-matched codeword comprising systematic bits and parity-check bits. Furthermore, the transmitting device jointly interleaves the systematic bits and parity-check bits of the rate-matched codeword to obtain an interleaved codeword. The systematic bits of the interleaved codeword are mapped to modulation label positions of a modulation constellation with first reliabilities, and the parity-check bits of the interleaved codeword are mapped to modulation label positions of the modulation constellation with second reliabilities.

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.

Abstract: A transmitting device and a receiving device for reliable reception of control messages such as downlink control information is provided. The transmitting device forms a control message which comprises control information, a first CRC word (W1) and a second CRC word (W2). The control message is sent to the receiving device which obtains a first CRC check outcome based on performing a first CRC check on the control message, and a second CRC check outcome based on performing a second CRC check on the control message. Thereby, more reliable reception of control messages is possible. Furthermore, the present application also relates to corresponding methods and a computer program.

Abstract: A codeword bit interleaving scheme for multilayer transmissions in a wireless communication system. The codeword bit interleaving scheme involves dividing columns of an interleaving matrix into at least two disjoint column groups based on transmission qualities (e.g., SNRs) of data transmission layers (e.g., MIMO layers). The column groups are then filled with codeword bits, starting with writing information bits into the column group(s) corresponding to the high-quality data transmission layers. After that, the column groups are all merged to restore the initial column arrangement of the interleaving matrix, and the codeword bits are read from the interleaving matrix row-wise and mapped to modulation symbols. The modulation symbols are in turn mapped to the data transmission layers themselves.

Abstract: Devices, methods and non-transitory computer-readable medium for adaptively selective retransmissions in wireless communications are disclosed. The present application allows enhancing short packet data retransmission performance under short delay constraints. Using a retransmission indication for at least one segment of consecutive forward error correction (FEC) encoded bits reduces feedback signaling overhead compared to signaling retransmission requests individually for each of the coded bits. Accordingly, active hybrid automatic repeat request (HARQ) transmissions with low amounts of feedback information are enabled.
