Solution Overview
Problem
The integration of PEI (Paging Early Indication) in NR systems poses challenges for coexistence with low-power wake-up signals, leading to increased power consumption and potential hardware complexity, which is not adequately addressed in existing technologies.
Innovation Solution
A method and apparatus that utilize low-power wake-up signals (LP WUS) to determine device groups, allowing terminals to selectively monitor PEI, thereby reducing unnecessary radio frequency activation and optimizing energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If PEI is integrated into NR systems to indicate paging monitoring requirements, then paging efficiency is improved, but power consumption increases and hardware complexity increases
Solution Approach 1:
The patent segments device groups into multiple groups (first device group, second device group, etc.) where each group has different PEI monitoring requirements. Devices are assigned to specific groups based on their characteristics, allowing selective PEI monitoring only for devices that need it, thereby reducing overall power consumption while maintaining paging efficiency.
Solution Approach 2:
Different device groups are assigned different PEI monitoring configurations locally. The first device group monitors PEI while the second device group does not, allowing each device to operate with optimal power consumption characteristics suited to its specific requirements rather than forcing a uniform configuration on all devices.
2Productivity
If PEI is integrated into NR systems to indicate paging monitoring requirements, then paging efficiency is improved, but hardware complexity increases
Solution Approach 1:
By segmenting devices into different groups with different PEI monitoring requirements, the patent reduces hardware complexity for devices in the second group that do not need to monitor PEI. Only devices in the first group require the additional hardware capabilities for PEI monitoring, allowing cost-effective deployment for devices with simpler requirements.
3Use of energy by moving object
If low-power wake-up signals are used to determine device groups, then power consumption is reduced, but coexistence with PEI becomes challenging
Solution Approach 1:
The patent implements dynamic adaptability by allowing the system to flexibly configure multiple device groups with different PEI monitoring requirements. The network can dynamically assign devices to appropriate groups based on their power consumption characteristics and paging needs, enabling seamless coexistence of low-power wake-up signals and PEI mechanisms without rigid constraints.
Solution Approach 2:
The patent changes the parameter of PEI monitoring requirement from a binary state (monitor or not monitor) to a multi-level configuration with multiple device groups. This parameter change allows fine-grained control over PEI monitoring behavior, enabling the system to adapt to different power consumption requirements while maintaining coexistence between wake-up signals and PEI.

AI summary
Disclosed in the present application are a method and apparatus used in a node for wireless communications. A node first receives a target information block and a target wake-up signal, the target wake-up signal being used for determining a first device group, and the first node being one device comprised in the first device group; and then the node determines whether to monitor a target paging early indicator, the target paging early indicator being associated with G1 device groups. The target information block is used for determining the G1 device groups, and any one of the G1 device groups comprises at least one device. A second device group is one of the G1 device groups, the first node belongs to the second device group, and the relationship between the first device group and the second device group is used for determining whether to monitor the target paging early indicator. According to the present application, the means of receiving a weak-up signal and a paging early indicator in a terminal-side energy saving scenario is improved so as to improve the overall performance of the system.
