Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing duplex modes in coordinated multi-point scenarios, leading to unnecessary time consumption and increased interference, particularly in full-duplex operations.
Innovation Solution
A method and device for user equipment (UE) to transmit capability information and channel measurement data to a serving base station, allowing the base station to select an appropriate duplex mode based on signal-to-interference-plus-noise ratio (SINR) information, enabling coordinated multi-point (CoMP) operations and reducing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the base station operates in full-duplex mode to improve communication efficiency, then data transmission rate is improved, but interference increases
Solution Approach 1:
The base station dynamically switches between half-duplex and full-duplex modes based on real-time channel conditions and interference levels. The duplex mode is not fixed but adapts to changing environmental conditions, allowing the system to optimize between throughput and interference management
Solution Approach 2:
The system changes the operational parameter of duplex mode (half-duplex vs. full-duplex) based on measured channel conditions. When interference is high, the system transitions to half-duplex mode; when conditions are favorable, it switches to full-duplex mode to maximize data transmission rate
2Productivity
If the base station selects duplex mode based on comprehensive channel measurement to improve communication efficiency, then service quality is improved, but time consumption for measurement increases
Solution Approach 1:
The base station performs channel measurements and evaluates duplex mode suitability in advance before actual data transmission. By conducting measurements preliminarily and caching results, the system avoids repeated measurements during active communication, reducing time loss while maintaining efficient operation
Solution Approach 2:
The base station autonomously performs channel measurements and makes duplex mode decisions without requiring external intervention or extensive coordination with other nodes. This self-service capability reduces overhead and accelerates the decision-making process
