A transmitter, a receiver and methods therein, configured to transmit a first type of synchronisation signal, in Msymbols l, 0≦i≦(M−1) and a second type of synchronisation signal in Msymbols k, 0≦j≦(M−1) of a subframe , wherein M≧M≧2. The transmitter comprises a processor, configured to determine in which symbols lthe synchronisation signal of the first type is to be transmitted, and in addition configured to calculate in which symbols k, the synchronisation signal of the second type is to be transmitted, by placing each of the Msymbols kat a symbol distance from an associated symbol l. The transmitter also comprises a transmitting circuit configured to transmit the synchronisation signals of the first type in the Msymbols l, and transmitting the synchronisation signals of the second type in the Msymbols k. 1. A transmitter for transmitting a first type of synchronisation signal , in Msymbols l , 0≦i≦(M−1) of a subframe and a second type of synchronisation signal in Msymbols k , 0≦j≦(M−1) of the subframe , the transmitter comprising: [{'sub': 'i', 'determine in which symbols lof the subframe the synchronisation signal of the first type is to be transmitted, and'}, {'sub': j', '2', 'j', 'i', '2', 'j', 'i', '1', 'i, 'calculate in which symbols kof the subframe, the synchronisation signal of the second type is to be transmitted, by placing each of the Msymbols kat a one or more determined symbol distance from an associated symbol l, wherein said one or more determined symbol distance between each of the Msymbols kand the respective associated symbol lis equal for all of the Msymbols lin the subframe; and'}], 'a processor, configured to [{'sub': 1', 'i, 'transmit the synchronisation signals of the first type in the determined Msymbols lof the subframe, and to'}, {'sub': 2', 'j, 'transmit the synchronisation signals of the second type in the calculated Msymbols kof the subframe;'}], 'a transmitting circuit configured to{'sub': 2', '1, 'wherein the subframe comprises N ...
