1. A method implemented in a wireless device configured to wirelessly connect to a first cell in a radio network, the method comprising:
determining a deployment alternative for a resynchronization signal, RSS, in the radio network, determining the deployment alternative comprising receiving an indication of the deployment alternative via system information, the determining of the deployment alternative including determining whether a time-frequency resource used for an RSS in a second cell in the radio network is a same time-frequency resource as a time-frequency resource used for an RSS in the first cell;
determining information about an RSS time-frequency resource used in the second cell in the radio network based at least in part on the determined deployment alternative;
detecting the RSS in the second cell using the determined information about the RSS time-frequency resource used in the second cell; and
when the determining of the deployment alternative indicates that the time-frequency resource used for the RSS in the first cell is different from the time-frequency resource used for the RSS in the second cell, then a frequency of the time-frequency resource used for the RSS in the second cell is determined based at least in part on a function of a cell identity of the second cell.
