LP-WUS Time-Domain Resource Configuration for Low-Power Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Determining the transmission resource of a low-power-consumption wake up signal (LP-WUS) is challenging, leading to increased power consumption in terminal devices.
Innovation Solution
The method involves configuring a terminal device with resource configuration information to determine the time domain resource of the LP-WUS, allowing it to periodically monitor the signal based on indicated periodicity and position, reducing power consumption by optimizing the monitoring duration and flexibility of resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal device continuously monitors the LP-WUS without determining time domain resource, then the terminal device can receive the LP-WUS signal, but the power consumption of the terminal device increases
Solution Approach 1:
The patent implements periodic monitoring of LP-WUS by configuring the terminal device with specific time domain resources including periodicity and time domain position. The terminal device wakes up at predetermined intervals to monitor for LP-WUS signals rather than continuously monitoring, which significantly reduces power consumption while maintaining reliable signal detection capability.
2Adaptability or versatility
If multiple pieces of resource configuration information are used to determine time domain resource, then the resource allocation flexibility is improved, but the signaling overheads increase
Solution Approach 1:
The patent combines multiple resource configuration parameters (periodicity, time domain position, and length) into a unified configuration framework. By merging these configuration elements and using bitmap-based resource indication, the system achieves flexible resource allocation while reducing signaling overhead compared to separate configuration messages for each parameter.
Solution Approach 2:
The patent uses configurable parameters such as periodicity values, time domain position offsets, and length indicators to dynamically adjust LP-WUS monitoring resources. These parameter changes enable flexible adaptation to different deployment scenarios while maintaining efficient signaling through standardized configuration formats.
3Reliability
If the terminal device monitors LP-WUS for longer duration, then the probability of receiving LP-WUS is improved, but the power consumption increases
Solution Approach 1:
The patent implements dynamic monitoring duration adjustment by configuring the terminal device with a specific length of time domain resource for LP-WUS monitoring. The monitoring duration is adapted based on signal characteristics and network conditions, allowing the terminal to extend or reduce monitoring time as needed while optimizing power consumption.

AI summary
A communication method and apparatus, the method including receiving, by a terminal device or a chip of the terminal device, first resource configuration information from a network device, where the first resource configuration information indicates a first time domain resource of a low power wake up signal (LP-WUS), and the LP-WUS is associated with wake up of the terminal device, and receiving the LP-WUS from the network device on at least a part of the first time domain resource.
