    Abstract: A network access node and a client device for generating and using cubic phase polynomial sequences (si, sj) of length L with a third order coefficient value a3 belonging to the subset of sequences () are described. The network access node transmits a control message to the client device, wherein the control message indicates the cyclical shift value NCS and the third order coefficient value a3. The client device receives the control message and determines a cubic polynomial phase sequence (si) belonging to the subset of sequences () based on the cyclical shift value NCS and the third order coefficient value a3. The client device thereafter transmits the determined cubic polynomial phase sequence (si) as a random access preamble to the network access node.

    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: A transmitter and a method therein, configured for generating a synchronization signal for Device-to-Device (D2D) communication utilizing a Single Carrier-Frequency Division Multiple Access (SC-FDMA) waveform. The method includes determining, by a transmitter, a synchronization sequence du[l] modulating a set of subcarriers, where |du[l]|=|du[L−1−l]|, l=0, 1, . . . , L−1, and |du[l]=K, for a positive constant K, where u is a root index and L is a length of the synchronization sequence du[l]. The method further includes selecting the root index u from a set of root indices, and generating a synchronization signal for D2D communication utilizing an SC-FDMA waveform based on the determined synchronization sequence du[l] and the selected root index u.
