1. A method of operating a wireless communication device connectable to a cellular network, the method comprising:
obtaining information indicating whether a wake-up signaling operation is activated for the wireless communication device in individual cells of the cellular network depending on a position of the cells of the cellular network in a paging escalation sequence, wherein the paging escalation sequence includes progressively increasing a paging radius around one or more most recently active cells, the paging escalation sequence includes a first stage in which the wake-up signaling operation is activated for the wireless communication device only in the one or more most recently active cells, and a second stage in which the wake-up signaling operation is only activated for the wireless communication device in one or more neighboring cells that surround the one or more most recently active cells,
determining, based on the obtained information and a current cell of the cellular network and a detected direction of movement for the wireless communication device, whether the wake-up signaling operation is activated for the wireless communication device in the current cell, and
upon determining that the wake-up signaling operation is activated in the current cell: monitoring for a wake-up signal prior to a paging occasion in accordance with the wake-up signaling operation.
