Wireless communication device, core network node and methods therein for extended drx paging cycle

A wireless communication device configured to handle an extended paging cycle, the extended paging cycle being used for receiving a paging message from a core network node comprised in a wireless communications network, and the extended paging cycle being longer than a frame number range of the wireless communications network, the wireless communication device being configured to:

• obtain a parameter related to a length of the extended paging cycle;
• obtain an information about when the wireless communication device has entered an idle mode, the idle mode being related to a connection between the wireless communication device and the core network node;
• and
• determine a time period when the wireless communication device is to monitor for the paging message, the determining being based on the parameter related to the length of the extended paging cycle and based on the information about when the wireless communication device has entered the idle mode.
