1Productivity
If dynamic radio resource allocation is implemented based on real-time channel state information, then network efficiency and data transmission quality are improved, but system complexity and configuration overhead increase
Solution Approach 1:
The patent implements dynamic radio resource allocation by enabling the base station to adjust resource allocation decisions based on real-time channel state information and user equipment capabilities. The system transitions from static to dynamic configuration, allowing adaptive modulation and coding schemes to be selected according to current network conditions, thereby improving network efficiency while managing complexity through automated decision-making processes.
Solution Approach 2:
The system changes key parameters such as modulation order, coding rate, and resource block allocation based on measured channel conditions and device capabilities. By dynamically adjusting these parameters, the system optimizes data transmission quality and network efficiency without requiring complete system reconfiguration, thus balancing performance improvement with complexity management.
2Reliability
If adaptive coding and modulation schemes are used to optimize network performance, then data transmission quality improves, but latency in configuration increases
Solution Approach 1:
The system performs preliminary configuration of multiple modulation and coding schemes during initial setup, pre-calculating and preparing resource allocation templates. This allows the system to quickly adapt to changing conditions without performing complex calculations in real-time, thereby maintaining high data transmission quality while minimizing configuration latency.
Solution Approach 2:
The patent implements feedback mechanisms where the base station receives channel state information from user equipment and adjusts coding and modulation schemes accordingly. This closed-loop approach enables rapid adaptation to changing network conditions, improving data transmission quality while reducing the time needed for reconfiguration through efficient feedback-driven decision-making.
3Productivity
If network slicing is dynamically adjusted based on user equipment capabilities, then resource utilization improves, but configuration complexity increases
Solution Approach 1:
The patent segments the network into multiple slices with distinct characteristics and resource allocation strategies. Each slice can be independently configured and optimized based on user equipment capabilities, allowing fine-grained control over resource utilization. This segmentation approach improves resource allocation efficiency while managing complexity by isolating configuration parameters into manageable slices.
Solution Approach 2:
The system implements a universal resource allocation framework that can serve multiple network slices and user equipment types through a single integrated mechanism. This multi-functional approach allows the base station to handle diverse service requirements using common procedures, thereby improving resource utilization across different slices while reducing overall configuration complexity through standardization.

AI summary
A system may include a base station central unit and a base station distributed unit. The base station central unit may include one or more processors and memory storing instructions that, when executed by the one or more processors, cause the base station central unit to send, to the base station distributed unit, an indication that a cell is associated with a first non-public network (NPN); and to send, to the base station distributed unit, a request for configuration of the cell for a wireless device that supports the first NPN. The base station distributed unit may include one or more processors and memory storing instructions that, when executed by the one or more processors, cause the base station distributed unit to receive the indication and the request for configuration of the cell.
