Sending and detecting synchronization signals and an associated information message
Embodiments herein relate to methods and apparatuses. A method performed by a network node (210) for sending to a wireless device (250) a first synchronization signal and an associated information message, for synchronization of the wireless device (250) with the network node (210) is provided. The network node (210) sends the first synchronization signal in OFDM symbols within a subframe, at least once in a time and frequency position in every one of the N OFDM symbols. For each sending of the first synchronization signal, the network node (210) 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. Embodiments herein also relate to a wireless device and method therein.
