Network node, wireless device, methods therein, for sending and detecting, respectively, synchronization signal and an associated information
Methods are disclosed which can be performed by a network node for sending to a wireless device a first synchronization signal and an associated information message, for synchronization of the wireless device with the network node. The network node and the wireless device operate in a wireless communications network. The network node sends the first synchronization signal in N OFDM symbols within a subframe, at least once in a time and frequency position in every one of the N OFDM symbols. N is equal or larger than 2. For each sending of the first synchronization signal, the network node sends an associated information message at a pre-defined time and frequency position in an OFDM symbol. The pre-defined time and frequency position is relative to the time and frequency position of the first synchronization signal. The associated information message is associated with the first synchronization signal.
