Jointly optimize network and device power saving

A processor for wireless communication, comprising:

• at least one controller coupled with at least one memory and configured to cause the processor to:
• receive an indication of one or more of a network energy saving (NES) configuration or an NES class;
• determine a remaining active time of the cell based at least in part on the NES configuration;
• and
• evaluate one or more cell-sleep conditions based at least in part on a user equipment (UE) cell-active threshold, a UE cell-sleep threshold, and a UE power saving state supported by the cell.

A method performed by a user equipment (UE), the method comprising:

• receiving an indication of one or more of a network energy saving (NES) configuration or an NES class;
• determining a remaining active time of a cell based at least in part on the NES configuration;
• and
• evaluating one or more cell-sleep conditions based at least in part on a UE cell-active threshold, a UE cell-sleep threshold, and a UE power saving state supported by the cell.

A network equipment (NE) for wireless communication, comprising:

• at least one memory;
• and
• at least one processor coupled with the at least one memory and configured to cause the NE to:
• establish an energy savings priority based on at least network energy savings and user equipment (UE) energy savings;
• and
• transmit a network energy saving (NES) configuration that is mapped to an NES class to a UE from which the UE establishes a (re) selection priority based at least in part on the network energy savings and the UE energy saving.
