Engineering Contradiction Analysis
1Productivity
If machine learning algorithms are implemented to dynamically adjust network parameters, then network performance and throughput are improved, but system complexity increases
Solution Approach 1:
An AI system acts as an intermediary between network conditions and resource allocation decisions. The AI system receives network state inputs, processes them through machine learning models, and generates resource allocation decisions, thereby mediating the complexity between raw network data and control actions.
Solution Approach 2:
The network system performs self-optimization through automated AI-driven resource allocation without requiring manual intervention. The machine learning models continuously learn from network data and automatically adjust parameters, enabling the system to serve and optimize itself.
2Adaptability or versatility
If dynamic resource allocation is implemented across heterogeneous wireless systems, then adaptability is improved, but device complexity increases
Solution Approach 1:
The AI system is designed to handle multiple wireless technologies (4G, 5G, WiFi) and various network conditions through a unified machine learning framework. This universal approach allows the same system to adapt to heterogeneous environments without requiring separate management mechanisms for each technology.
Solution Approach 2:
The system dynamically adjusts network parameters such as resource block allocations, bandwidth parts, and transmission configurations based on real-time network conditions. By changing parameters adaptively through AI-driven decisions, the system achieves versatility across different wireless technologies and scenarios.
3Use of energy by moving object
If AI-based dynamic bandwidth allocation is implemented, then energy efficiency is improved, but computational requirements increase
Solution Approach 1:
The AI system performs preliminary analysis of network conditions and traffic patterns to predict future resource requirements. By anticipating demand before it occurs, the system can allocate resources more efficiently and avoid unnecessary computational overhead during peak periods.
Solution Approach 2:
The system implements continuous feedback loops where AI models receive performance metrics and energy consumption data, then adjust resource allocation strategies accordingly. This feedback mechanism enables the system to learn from past decisions and optimize the balance between energy efficiency and computational requirements over time.

AI summary
A method for allocating communication resources in a wireless network by collecting data related to network conditions and terminal device requirements; selecting predetermined resource block allocations for terminal devices and wherein a sub-carrier spacing is selected based on a numerology for the bandwidth part (BWP) which influences RBG configuration and allocation of RBs to terminal devices; encoding the resource block allocations into a resource indication information with a most significant bit (MSB) indicating whether a resource block set belongs to the frequency domain resources of the data channel; and transmitting the resource indication information to the terminal devices.
