Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a second-type BWP including discrete frequency domain resources is used to improve spectrum efficiency, then spectrum efficiency is improved, but the method to determine frequency domain location and parameter is not specified
Solution Approach 1:
The terminal device autonomously determines the frequency domain location and parameters of the second-type BWP by using a parameter determining rule based on its own parameter type and available reference points, without requiring additional network device instructions. This self-service approach resolves the undefined determination method while maintaining spectrum efficiency benefits
Solution Approach 2:
The patent applies parameter changes by selecting different parameter determining rules based on the parameter type of the second-type BWP. The terminal device changes its determination approach according to the specific parameter characteristics, enabling flexible and adaptive frequency domain resource allocation that improves spectrum efficiency without adding system complexity
2Loss of energy
If discrete frequency domain resources are allocated to improve spectrum efficiency, then spectrum efficiency is improved, but scheduling overhead increases
Solution Approach 1:
The patent extracts the frequency domain location determination from the network device's scheduling instructions and relocates it to the terminal device's autonomous decision-making process. By taking out the determination function from network control signaling, the patent reduces scheduling overhead while maintaining the discrete frequency domain resource allocation that improves spectrum efficiency
Solution Approach 2:
The terminal device uses a copy of the parameter determining rule locally to replicate the frequency domain location determination that would otherwise require network device computation and signaling. This copying approach allows the terminal to independently determine resource locations, reducing the information exchange overhead while preserving spectrum efficiency gains
