Power saving techniques

A wireless communication method, comprising:

• configuring physical resources for a communication node or a group of one or more communication nodes,
• wherein the physical resources include a control resource set (CORESET), a search space, and a control channel element (CCE);
• generating a channel-based wake-up signal (WUS) by mapping modulated symbols and a demodulation reference signal (DMRS) onto the physical resources,
• wherein the modulated symbols include an indication information that indicates whether the communication node or the one or more communication nodes are triggered to monitor a paging occasion;
• and
• transmitting the channel-based WUS.

A wireless communication apparatus, comprising:

• a processor configured to implement a method, wherein the processor is configured to:
• receive, by a communication node, a channel-based wake-up signal (WUS) that is included in a channel,
• wherein the channel-based WUS is associated with the communication node or with a group to which the communication node belongs, and
• wherein the channel-based WUS includes an indication information that indicates whether the communication node is triggered to monitor a paging occasion;
• and
• determine whether to perform a paging related operation based on the indication information.
