Patent ID: 11259259

Abstract:
A transmitter, a receiver and methods therein, configured to transmit a first type of synchronisation signal, in M1 symbols li,, 0≤i≤(M1−1) and a second type of synchronisation signal in M2 symbols kj,, 0≤j≤(M2−1) of a subframe, wherein M2≥M1≥2. The transmitter comprises a processor, configured to determine in which symbols li the synchronisation signal of the first type is to be transmitted, and in addition configured to calculate in which symbols kj, the synchronisation signal of the second type is to be transmitted, by placing each of the M2 symbols kj at a symbol distance from an associated symbol li. The transmitter also comprises a transmitting circuit configured to transmit the synchronisation signals of the first type in the M1 symbols li, and transmitting the synchronisation signals of the second type in the M2 symbols kj.
