Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems cannot accurately determine interference by measuring received power from all directions, lacking the ability to assess the direction and intensity of radio waves, which hinders precise interference detection.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If received power is measured from all directions in the current wireless communication system, then the measurement process is simple, but the ability to accurately determine interference is insufficient
Solution Approach 1:
The patent divides the omnidirectional measurement into multiple directional beam measurements. The terminal apparatus measures received power separately for each beam direction, allowing the base station to determine not only the total received power but also the directional characteristics of the signal, thereby improving interference detection accuracy while maintaining manageable system complexity through standardized beam measurement procedures
Solution Approach 2:
The patent adds the directional dimension to the traditional scalar received power measurement. By introducing beam direction as a new measurement dimension, the system transitions from measuring only the magnitude of received power to measuring both magnitude and direction, enabling accurate determination of interference sources without requiring overly complex measurement equipment
2Reliability
If directional beam measurement is implemented, then interference determination accuracy is improved, but measurement complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the terminal apparatus performs beam measurements and reports the results to the base station. This feedback loop allows the base station to use the directional received power information to accurately determine interference conditions and adjust transmission strategies, improving reliability while the standardized feedback protocol keeps measurement complexity manageable
Solution Approach 2:
The terminal apparatus autonomously performs the beam measurements using its own reception capabilities and independently determines the received power for each beam direction. This self-service approach eliminates the need for complex external measurement equipment at the base station, improving measurement reliability while keeping the measurement system complexity at the terminal level where it is already present for normal communication
