The present disclosure relates to methods and devices for improved cell detection. In particular the disclosure relates to cell detection within a group of cells with high requirements of low latency. The disclosure also relates to corresponding computer program. The disclosure proposes a method, performed in a wireless device, for cell detection within a group of cells. The method comprises detecting a first synchronization signal of a first cell in the group, wherein the detecting comprises searching for any of a set of predefined synchronization signals. The method further comprises obtaining, based on the detected first synchronization signal, information defining a subset of the predefined synchronization signals, wherein the subset defines synchronization signals that are possible within the group of cells. The method also comprises decoding one or more further synchronization signals of cells in the group of cells using the obtained information.
