LP WUS Configuration Area IDs for Lower UE Power Consumption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for configuring low-power wake-up signal (LP WUS) configurations in user equipment (UE) are inefficient, leading to increased power consumption when UE moves between cells with different LP WUS configurations, as the UE needs to repeatedly turn on its main receiver to re-determine the LP WUS configuration.
Innovation Solution
Configuring a wake-up signal configuration area identifier (ID) for network devices, ensuring that all devices within the same area have the same configuration, allowing UE to maintain the LP receiver state across cell transitions without needing to turn on the main receiver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE uses the main receiver to receive system messages for LP WUS configuration, then the UE can obtain accurate wake-up signal configuration information, but the power consumption increases when the UE moves between cells with different configurations
Solution Approach 1:
The network device performs preliminary action by configuring and broadcasting the wake-up signal configuration area ID before the UE needs to re-determine the LP WUS configuration. This allows the UE to use the pre-configured area ID to quickly determine whether to wake up the main receiver, avoiding unnecessary power consumption while maintaining configuration accuracy through the area-based identification mechanism
2Adaptability or versatility
If the UE turns on the main receiver to re-determine LP WUS configuration when moving between cells, then the UE can adapt to different cell configurations, but the power consumption increases
Solution Approach 1:
The wake-up signal configuration area ID acts as an intermediary element between the network device and the UE. Instead of the UE directly receiving and processing complete LP WUS configuration messages from the main receiver, the UE uses the area ID as an intermediary identifier to determine whether configuration re-determination is needed, thereby maintaining adaptability while reducing power consumption
3Ease of operation
If the network device sends LP WUS configuration through system messages, then the configuration can be transmitted to the UE, but the UE cannot maintain LP receiver state across cell transitions
Solution Approach 1:
The network device segments the LP WUS configuration information into two parts: the wake-up signal configuration area ID (which can be transmitted and stored) and the actual LP WUS parameters (which are only retrieved when needed). This segmentation allows the configuration to be transmitted efficiently while enabling the UE to maintain the LP receiver state across cell transitions by using the stored area ID for quick configuration determination
