Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If spectrum sharing is implemented in unlicensed and licensed frequency bands to improve spectrum utilization efficiency, then spectrum resource utilization is improved, but interference management becomes more complex and communication quality deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the base station sends spectrum occupancy information to the terminal, and the terminal adjusts its transmission based on this feedback. This allows the system to dynamically respond to spectrum conditions, enabling multiple nodes to share spectrum resources efficiently while managing interference through coordinated transmission decisions.
Solution Approach 2:
The patent introduces spectrum occupancy information as an intermediary that mediates between multiple transmitting nodes. This information acts as a coordinating mechanism that allows nodes to understand spectrum usage conditions and adjust their transmissions accordingly, resolving the interference problem while maintaining high spectrum utilization.
2Adaptability or versatility
If contention-based spectrum occupation is used in unlicensed frequency bands to reduce cost and increase availability, then spectrum accessibility is improved, but transmission reliability deteriorates due to unpredictable interference
Solution Approach 1:
The patent applies preliminary action by having the base station determine and notify the terminal about spectrum occupancy information before transmission occurs. This allows the terminal to prepare appropriate transmission strategies in advance, ensuring reliable communication while maintaining access to unlicensed spectrum resources.
Solution Approach 2:
The terminal uses the received spectrum occupancy information to autonomously adjust its transmission parameters and decisions. This self-service mechanism enables the terminal to reliably manage its transmissions based on current spectrum conditions without requiring continuous base station control, maintaining both accessibility and reliability.
3Use of energy by moving object
If timer-based state control is used to manage discontinuous transmission states, then power consumption is reduced, but transmission delay increases when spectrum becomes available
Solution Approach 1:
The patent makes the timer operation dynamic by allowing it to be suspended or continued based on spectrum occupancy conditions. When the base station determines that spectrum is occupied, it sends corresponding information to the terminal, which then suspends the timer to avoid unnecessary state transitions and reduce delay, while still maintaining power-efficient operation when spectrum is unavailable.
