Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communication technologies face challenges in combining wake-up signal monitoring with low-power wake-up radio (LP-WUR) to effectively reduce latency and power consumption in mobile terminals.
Innovation Solution
Implementing a method and apparatus that involve applying search space set groups, PDCCH skipping durations, and bandwidth parts (BWPs) to optimize wake-up signal monitoring, including performing wake-up signal monitoring in specific search space set groups, during PDCCH skipping durations, and switching to different search space set groups or BWPs to reduce power consumption and latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If wake-up signal monitoring is performed continuously to reduce latency, then response time is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic switching between different monitoring modes (continuous PDCCH monitoring, wake-up signal monitoring, and PDCCH skipping) based on traffic conditions and network configuration. The terminal can adaptively adjust its monitoring behavior to balance latency and power consumption requirements.
Solution Approach 2:
The patent changes the monitoring parameters dynamically by switching between different search space set groups (first search space set group for continuous monitoring, second search space set group for reduced monitoring) and adjusting PDCCH skipping durations based on traffic patterns and power saving requirements.
2Reliability
If PDCCH monitoring is performed frequently to ensure timely data reception, then reliability is improved, but power consumption increases
Solution Approach 1:
The patent segments PDCCH monitoring into different phases: initial monitoring using the first search space set group for reliable data reception, and subsequent monitoring using the second search space set group or wake-up signal monitoring for power saving. This segmentation allows the system to maintain reliability when needed while reducing power consumption during idle periods.
Solution Approach 2:
The patent implements periodic wake-up signal monitoring instead of continuous PDCCH monitoring during idle periods. The terminal periodically checks for wake-up signals at configured intervals, maintaining the ability to receive data reliably while significantly reducing power consumption compared to continuous monitoring.
3Productivity
If search space set groups are switched to optimize monitoring, then monitoring efficiency is improved, but device complexity increases
Solution Approach 1:
The patent pre-configures multiple search space set groups (first and second search space set groups) with different monitoring parameters before operation. The network configures these groups in advance with appropriate PDCCH monitoring periodicities and offsets, so the terminal can switch between them without complex real-time calculations, reducing operational complexity while maintaining monitoring efficiency.
