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: 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.

Abstract: Example transmit devices, receive devices, and related methods are described herein, In one example, transmission burst information is provided to a receive device by downlink control signalling. An example transmit device is configured to transmit a Downlink Control Information, or DCI, the DCI including the transmission burst information. The DCI has the same number of bits as a DCI format used for PDSCH scheduling.

Abstract: A wireless communication system includes at least one transmit node having at least two transmit antenna ports, and at least one receive node having at least one receive antenna port. User information is transmitted between the at least two transmit antenna ports and the at least one receive antenna port on a radio propagation channel. A reconstructed channel state information (R-CSI) for a reconstructed radio propagation channel is computed. The reconstructed radio propagation channel is obtained as an estimated radio propagation channel compensated by a function of an estimated signal power imbalance between the at least two transmit antenna ports. And an indicative of the estimated signal power imbalance and the R-CSI is sent to the at least one transmit node.
