Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the amount of signals transmitted via wireless communication network increases, then the network capacity and data transmission capability improve, but interference signals increase and transmission efficiency decreases
Solution Approach 1:
The patent implements a feedback mechanism where the cooperation base station transmits feedback information (such as channel state information, interference level, or recommended resource allocation) to the serving base station based on the received interference signal characteristics. The serving base station then adjusts its transmission parameters (power, resource blocks, precoding) based on this feedback, creating a closed-loop system that dynamically mitigates interference while maintaining high network capacity
Solution Approach 2:
The patent introduces a cooperation base station as an intermediary entity between the serving base station and the terminal. This cooperation base station receives and analyzes interference signals, generates feedback information about the interference characteristics, and provides recommendations to the serving base station. This intermediary structure enables sophisticated interference management without requiring direct complex interaction between the serving base station and terminal, thus maintaining high productivity while reducing harmful interference effects
2Productivity
If interference control schemes are applied to minimize interference effects, then transmission efficiency improves, but system complexity increases due to coordination between base stations
Solution Approach 1:
The patent divides the interference management function into separate modules: the cooperation base station handles interference signal reception, analysis, and feedback generation, while the serving base station handles transmission parameter adjustment based on feedback. This segmentation allows each base station to perform a specialized function, improving transmission efficiency through coordinated interference control while distributing system complexity across multiple independent functional units rather than concentrating it in one complex system

AI summary
Provided is a data transmission system that may determine a multiple input multiple output dynamic spectrum management (MIMO-DSM) operation mode of a base station based on information associated with a data transmission route and a computational capability of each base station. A terminal may generate feedback information based on a cooperation level between base stations and may transmit the generated feedback information to a serving base station. The serving base station may select terminals that may receive data from among a plurality of terminals through a MIMO-DSM algorithm and a user scheduling based on the feedback information.
