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.

Abstract: A method is provided for arranging transmissions on a downlink carrier c, spanning a frequency range Fc, in a mobile radio communications system, wherein a bandwidth of Fc belongs to a set of predefined channel bandwidths in the communications system, and wherein the carrier c comprises a reference signal defined in the communications system. A configurable frequency range FRS comprising a set of time-frequency resources for comprising the reference signal of the carrier c is provided. Information associated with the configuration of said frequency range FRS is signaled to a receiver in the communications system, such that c can be deployed over a frequency range F smaller than Fc when the frequency range FRS is configured within F and any other transmissions on the carrier c are arranged to be within F.
