User node, a network node and methods for wireless communication

A network node for a wireless communication network, the network node comprising:

• a processor;
• and
• a memory having processor-executable instructions stored to be executed by the processor,
• wherein the processor-executable instructions cause the processor to:
• receive from a user node a message comprising 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 a network node, wherein the indication comprises a bit value associated with a selected wake-up latency from a list of predefined wake-up latencies based on an actual wake-up latency of the user node, and wherein a bit combination of “00” indicates that the user node does not support wake-up signaling;
• and
• set a wake-up offset for the user node based on the at least one wake-up latency, 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.

A method comprising:

• determining, by a user node, 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 a network node of a wireless communication network;
• selecting the at least one wake-up latency from a list of predefined wake-up latencies based on an actual wake-up latency of the user node, wherein the indication comprises a bit value associated with the selected wake-up latency, and wherein a bit combination of “00” indicates that the user node does not support wake-up signaling;
• determining, by the user node, a message comprising the indication;
• and
• transmitting, by the user node, the message to the network node.
