Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple wireless communication technologies are supported at UEs, then communication capability and versatility are improved, but interference between technologies increases error rates and reduces signal performance
Solution Approach 1:
The patent implements a feedback mechanism where the receiving node detects reception failures of response packets, identifies interference as the cause through energy level detection, and sends feedback information to the transmitting node. This feedback loop enables dynamic adjustment of transmission parameters to mitigate interference while maintaining support for multiple communication technologies.
Solution Approach 2:
The patent dynamically changes transmission parameters including reconfiguring the transmitting method for response packets, adjusting beamforming settings, and modifying channel information based on detected interference conditions. These parameter changes allow the system to adapt to interference scenarios while maintaining versatility across multiple wireless communication technologies.
2Reliability
If interference detection and reconfiguration mechanisms are implemented, then signal performance and reliability are improved, but system complexity and processing overhead increase
Solution Approach 1:
The patent enables the communication system to automatically detect interference conditions through energy level detection, identify the cause of reception failures, and reconfigure transmission parameters without requiring complex external control mechanisms. The system serves itself by autonomously adapting to interference scenarios, reducing the need for complex external management while improving reliability.

AI summary
A method for transmitting data by a transmission node in a wireless communication system is provided. The method includes transmitting, to a base station, a channel information request, transmitting, to the base station, a data packet based on a first channel information value received in response to the transmitted channel information request, and awaiting reception of a response packet indicating reception of the data packet from the base station, if the reception of the response packet fails during a predetermined time interval, detecting an energy level of a signal received in the predetermined time interval, and reconfiguring one of a transmitting method for the response packet and a transmitting method for a next data packet based on the detected energy level
