Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in coordinating discontinuous transmission and reception patterns across cells to minimize interference and optimize energy efficiency, particularly in managing active and inactive periods and power levels, leading to suboptimal network performance and energy savings.
Innovation Solution
The proposed solution involves an apparatus and method that share information elements containing spatial adaptation and power adaptation configurations, along with discontinuous transmission and reception patterns, between network entities to coordinate cell DTX/DRX patterns, allowing neighboring cells to adjust their configurations to minimize interference and optimize energy usage by selecting active periods when the neighboring cell is inactive or using lower power levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If discontinuous transmission and reception patterns are implemented across multiple cells, then energy efficiency is improved, but interference between cells increases
Solution Approach 1:
The patent implements feedback mechanisms where network entities exchange information elements containing DTX/DRX pattern configurations, spatial adaptation information, and power adaptation configurations. This feedback loop allows cells to adjust their transmission patterns based on neighboring cell activities, enabling dynamic coordination that reduces interference while maintaining energy savings.
Solution Approach 2:
The patent introduces dynamic coordination of DTX/DRX patterns across cells, allowing transmission and reception schedules to be adjusted in real-time based on network conditions. The system can switch between different transmission patterns and power levels dynamically, enabling optimal balance between energy efficiency and interference management.
2Reliability
If spatial adaptation and power adaptation configurations are coordinated between cells, then network performance is improved, but system complexity increases
Solution Approach 1:
The patent segments the coordination function into separate information elements that can be independently processed and transmitted between cells. The information elements are divided into spatial adaptation configuration, power adaptation configuration, and DTX/DRX pattern information, allowing modular processing and reducing the complexity of handling comprehensive coordination data.
Solution Approach 2:
The patent introduces information elements as intermediary data structures that facilitate coordination between cells. These standardized information elements act as mediators, carrying necessary configuration data between network entities without requiring direct complex interactions, thereby simplifying the overall system architecture.
3Object-generated harmful factors
If cells select active periods when neighboring cells are inactive, then interference is reduced, but coordination overhead increases
Solution Approach 1:
The patent implements periodic exchange of information elements containing DTX/DRX pattern configurations between cells. This periodic coordination allows cells to synchronize their active periods and reduce interference without requiring continuous real-time communication, thereby managing coordination overhead while maintaining effective interference reduction.
