Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate signaling is used to control power amplifying gain for the forwarding link, then the power control accuracy is improved, but the signaling load increases
Solution Approach 1:
The patent combines the power control information for the forwarding link with the power control information for the control link into a single signaling message. The base station transmits unified power control information that contains both the first power control information (for control link) and the second power control information (for forwarding link), thereby reducing signaling overhead while maintaining accurate power control for both links
Solution Approach 2:
The patent creates a universal power control information structure that serves multiple functions simultaneously. The unified power control information can be used by the repeater to determine both the transmission power for the control link and the power amplifying gain for the forwarding link, making the signaling mechanism multi-functional and efficient
2Adaptability or versatility
If multiple power parameters are transmitted for power control, then the power control flexibility is improved, but the signaling overhead increases
Solution Approach 1:
The patent segments the power control information into distinct fields within a unified structure. The power control information is divided into a first field (for control link power control) and a second field (for forwarding link power amplifying gain), allowing flexible interpretation and use of different power parameters while maintaining a compact signaling format
Solution Approach 2:
The patent enables dynamic parameter changes by allowing the repeater to interpret the power control information differently based on the link type. The same power control message can provide absolute power values for the control link while providing relative gain adjustments for the forwarding link, achieving flexibility without increasing signaling overhead
