Methods, a user node and a network node are provided. The user node is configured to determine an indication of at least one wake-up latency of the user node, the at least one wake-up latency being a time period for the user node to wake-up and start to monitor a downlink channel transmitted by the network node of a wireless communication network; determine a message comprising the indication; and transmit the message to the network node. The network node is configured to receive from the user node a message, and set a wake-up offset for the user node based on the at least one wake-up latency comprised in the message, the wake-up offset being a time period between a wake-up signal transmission and a subsequent downlink channel transmission from the network node to the user node.
