The present disclosure relates to transmitting synchronization signals and in particular to so called beam sweep. In particular the disclosure relates to methods for providing synchronization using synchronization sequences that are transmitted at different points in time. The disclosure also relates to corresponding devices and computer programs. A method in a network node, for transmitting synchronization sequences of a synchronization signal to one or more receiving wireless devices, comprises determining multiple synchronization sequences, such that each synchronization sequence comprises a respective timing indication, whereby each synchronization sequence enables determination of a time of an event in a receiving wireless device and transmitting the synchronization sequences to the one or more wireless devices, at different points in time.

The example method further includes, in the same wireless device, receiving, in a first subframe, a first Orthogonal Frequency-Division Multiplexing (OFDM) transmission formatted according to a first numerology and receiving, in a second subframe, a second OFDM transmission formatted according to a second numerology, the second numerology differing from the first numerology.

In one embodiment, a network node is configured to determine to configure the first signal to be located at a subcarrier except at an edge sub-carrier of a resource block, RB; transmit the configuration of the first signal to the WD; and receive a physical uplink shared channel, PUSCH, signaling and the first signal from the WD based at least in part on the determined configuration. In one embodiment, a WD is configured to perform a de-inter-carrier-interference (de-ICI) filter estimation on a first received signal and a second received signal; apply a de-ICI filter to a third received signal, the de-ICI filter being based on the de-ICI filter estimation; and after the application of the de-ICI filter, de-interleaved map and demodulate the third received signal.
