Wireless Communication Power-Saving Validation Across Multi-TRP Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication devices face challenges in reducing power consumption due to complex processing requirements and synchronization issues between multiple transmission and reception points (TRPs) in multi-TRP systems, leading to inefficient power saving techniques.
Innovation Solution
A method for wireless devices to determine the validity of power saving parameters based on high-layer signaling or predefined information, aligning power saving indications across TRPs by using control resource sets and search space configurations, and applying valid power saving parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If power saving parameters are applied without validity determination, then power saving efficiency is improved, but synchronization issues between TRPs cause unreliable power saving application
Solution Approach 1:
The patent applies preliminary action by having the wireless device determine the validity of power saving parameters before actually applying them. The device checks whether the indicated power saving parameter is valid based on pre-configured information or higher layer signaling before executing the power saving operation, ensuring reliable synchronization across TRPs while still achieving power savings when conditions are met
2Productivity
If complex processing is performed for monitoring control channels, then transmission performance is improved, but terminal power consumption increases
Solution Approach 1:
The patent applies local quality by enabling different power saving behaviors for different search spaces or control channels based on their specific characteristics. The wireless device determines validity of power saving parameters on a per-search-space basis, allowing optimized power consumption for each local area (search space) while maintaining overall transmission performance through selective power saving application
