Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current techniques for reducing intercell interference in wireless communication systems are limited, as they primarily focus on preventing mobile stations from recognizing signals from other cells, which restricts performance improvement in coordinated multi-point systems.
Innovation Solution
Implementing a method that uses a common permutation mapping across multiple base stations to communicate with a single mobile unit, allowing for coordinated signal processing and data extraction, thereby creating permutation zones that reduce intercell interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional intercell interference reduction techniques are used, then mobile stations cannot recognize signals from other cells, but performance improvement in coordinated multi-point systems is restricted
Solution Approach 1:
The patent segments the communication system into different zones (first zone with first permutation mapping, second zone with second permutation mapping) to enable coordinated multi-point communication. This segmentation allows the system to prevent interference in certain zones while maintaining performance improvement capabilities in others through coordinated signal processing across multiple base stations.
Solution Approach 2:
The patent changes the permutation mapping parameter across different zones to manage interference. By using a first permutation mapping in the first zone and a second permutation mapping in the second zone, the system can control signal recognition and interference patterns, enabling both interference prevention and performance improvement through coordinated multi-point transmission.
2Productivity
If universal resource reuse is implemented, then wireless communication resource demand is met, but intercell interference increases
Solution Approach 1:
The patent applies local quality by implementing different permutation mappings in different spatial zones. The first permutation mapping is used in the first zone while the second permutation mapping is used in the second zone, allowing localized interference management while maintaining overall resource reuse efficiency. This enables high resource utilization in certain areas without causing excessive interference elsewhere.
3Object-affected harmful factors
If sector specific frequency and temporal permutation is used, then inter-sector interference averaging is improved, but coordinated multi-point communication capability is limited
Solution Approach 1:
The patent implements universality by creating a system where multiple base stations can simultaneously communicate with a mobile unit using coordinated permutation mappings. The first and second base stations both use the first permutation mapping in the first zone, enabling multi-point communication while maintaining interference averaging benefits. This universal approach allows the same permutation mechanism to serve both interference reduction and multi-point communication goals.

AI summary
The present subject matter provides a method for implementation in a wireless communication system that includes a plurality of base stations for providing wireless connectivity to at least a first mobile unit. A first signal processed using a first permutation mapping is communicated between the first mobile unit and a first base station. A second signal processed using the first permutation mapping is communicated between the first mobile unit and a second base station different than the first base station. The first and second signals are processed based on the first permutation mapping to extract data therefrom.
