Radio Access Point Coordination for Wireless Resource Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, the coexistence of User Equipment (UE) that supports Coordinated Multi-Point Transmission and Reception (CoMP) technology and UE that does not, within the same coverage area, leads to interference and challenges in coordinating radio access points, particularly for UE not suitable for reporting various interference environments.
Innovation Solution
A method and device that manage wireless resources by exchanging coordination-related information between radio access points, calculating participation ratios of UE in CoMP, and applying valid CoMP information to manage resources until an update is received, enabling UE not suitable for reporting interferences to harmoniously participate in coordination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Coordinated Multi-Point Transmission and Reception (CoMP) technology is implemented for UE that supports it, then system performance and interference management are improved, but device complexity and coordination overhead increase due to the need for separate handling of CoMP-capable and non-CoMP-capable UE
Solution Approach 1:
The patent segments the coverage area into CoMP coordination regions and non-CoMP regions, allowing different interference management strategies to be applied in each segment. This enables improved interference management for CoMP-capable UE while avoiding unnecessary coordination overhead for non-CoMP-capable UE, thus resolving the technical contradiction between reliability improvement and device complexity increase.
2Measurement precision
If coordination information is exchanged between radio access points for all UE, then coordination accuracy is improved, but signaling overhead and processing time increase
Solution Approach 1:
The patent applies local quality by providing detailed coordination information exchange only in regions where CoMP-capable UE are present, while using simplified or no coordination for regions with only non-CoMP-capable UE. This approach maintains high coordination accuracy where needed while significantly reducing signaling overhead and processing time overall, thus resolving the technical contradiction between measurement precision improvement and time loss.
