AI Technical Summary
Technical Problem
Existing 5G networks consume unnecessary energy due to activities like always-on cell-specific reference signals and beamforming, even when there is no data transmission, leading to inefficiencies and increased environmental impact.
Method used
Implementing a wireless transmit-receive unit (WTRU) configured for network energy saving (NES) groups, which monitors downlink resources and adjusts DRX cycles based on network energy saving states, allowing for optimized reception and transmission strategies.
Benefits of technology
Reduces unnecessary energy consumption by minimizing activities like beamforming and always-on signals, enhancing network efficiency and environmental sustainability while maintaining effective communication.

Abstract
We provide WTRUs related to energy-saving networks. [Solution] The WTRU may receive configuration information indicating that the second cell should be used for Paging Early Notification (PEI) monitoring when the first cell is a camp cell and / or the first cell is in a network energy saving (NES) state. Based on the determination that the first cell is in an NES state, the WTRU may monitor PEI through the second cell. The WTRU may receive PEI through the second cell. The WTRU may monitor paging through the first cell and / or the second cell based on PEI subgroups. If a page is received through the second cell, the WTRU may send an instruction through the second cell indicating the identity of the first cell. If a page is received through the first cell, the WTRU may send a signal through the first cell.
