Abstract: A system and method for communication between a wireless communication device, a wireless communication node, and a core network are disclosed herein. In one embodiment, the system and method are configured to receive, by the core network, communication configuration information associated with a wireless communication device. The core network can refrain from transmitting to a wireless communication node a downlink packet size associated with the wireless communication device, when a downlink data packet size is greater than a downlink transmission capability of the wireless communication device. The core network can transmit to the wireless communication node, the downlink packet size in a paging message, when the downlink data packet size is less than or equal to the downlink transmission capability of the wireless communication device.
