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: In a radio communication system, a number of downlink component carriers can be aggregated for communication between a network node and a User Equipment (UE). A set of downlink component carriers is determined from the number of downlink component carriers. A downlink control channel for the UE is arranged to include information being usable for identifying at least one downlink component carrier of the set of downlink component carriers. A channel quality report is to be provided for each one of the at least one identified downlink component carrier.

Abstract: Methods and apparatus are provided for facilitating synchronization between a base station (BS) and a user equipment (UE) in a mobile communication system. The UE receives a synchronization signal originated by the BS. The synchronization signal is encoded with a selected cyclically permutable (CP) codeword. The selected CP codeword is selected from a set of CP codewords. Encoding of the synchronization signal is facilitated by a repetitive cyclically permutable (RCP) codeword derivable from the selected CP codeword. The RCP codeword has a plurality of codeword elements each associated with a value, the value of at least one codeword element in the RCP codeword being repeated in another codeword element position in the RCP codeword. And the synchronization signal is decoded in accordance with repetitive structure of the RCP codeword.
