Low-Power Wake-Up Signal Timing for PDCCH Monitoring

The patent applies preliminary action by including an offset indicator in the LP-WUS message that tells the UE in advance when to activate its high-power radio component. The UE calculates the activation time by adding the indicated offset to the LP-WUS reception time, allowing it to prepare and activate exactly when needed rather than immediately or blindly waiting, thus balancing reliability and power consumption.

The patent applies feedback by providing the UE with explicit timing information through the offset indicator in the LP-WUS message. This feedback mechanism allows the UE to accurately determine when to activate its high-power radio component based on network-provided timing guidance, ensuring timely activation without excessive power consumption and maintaining communication reliability.

The patent applies dynamics by enabling the UE to dynamically switch between DRX (discontinuous reception) and active monitoring states. The UE uses DRX to monitor for LP-WUS messages in low-power mode and only activates full PDCCH monitoring when triggered by an LP-WUS, allowing it to adapt its monitoring behavior to actual communication needs and significantly reducing power consumption while maintaining reliability.

The patent applies parameter changes by modifying the activation timing parameter based on the offset indicator received in the LP-WUS message. Instead of using fixed early activation or continuous monitoring, the UE adjusts its activation time parameter dynamically based on the indicated offset, ensuring it activates just in time for upcoming PDCCH occasions and avoiding unnecessary early activation that would waste power resources.
