Abstract: The present disclosure relates to a simple and power-efficient procedure that allows using wake-up signaling in inter-cell mobility scenarios. The procedure is based on configuring a Wake-Up Signal (WUS) Beacon Occasion (WBO) for each Tracking Area (TA) of a user device. A WUS beacon corresponding to each cell in the TA is transmitted once at a cell-specific time offset within the WBO. The WBO is configured together with a mapping table that maps each of the cell-specific time offsets to cell-specific information. The cell-specific information may comprise a cell ID and/or an indicator of a cell-specific frequency and/or cell-specific frequency range to be used for synchronization signal reception (e.g., Global Synchronization Channel Number (GSCN)). Each TA comprises intra-frequency cells only. By using the WBO, the user device may reduce its power consumption by avoiding switching from its sleep state to its active state when doing cell reselections in the TA.
