Problem
Existing wireless communication systems face challenges in dynamically adjusting cell system information in response to changes in user equipment distribution and service requirements, leading to increased network maintenance complexity and inability to accommodate changing requirements, such as inter-cell interference and limited control channel capacities.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cell system information (cell ID, carrier frequency, bandwidth) is fixed after network planning, then network planning completeness is maintained, but network adaptability to changing user equipment distribution and service requirements deteriorates
Solution Approach 1:
The patent implements dynamic cell system information by allowing base stations to adjust cell IDs, carrier frequencies, and bandwidth configurations in real-time based on user equipment distribution and service requirements. This transforms the static cell configuration into a dynamic system that can adapt to changing network conditions without requiring complete network replanning.
Solution Approach 2:
The patent enables base stations to autonomously adjust their own cell system information and notify relevant parties without requiring manual network planning intervention. Each base station can independently modify its configuration parameters based on local conditions, reducing the complexity of centralized network maintenance while maintaining overall network consistency.
2Adaptability or versatility
If new cells are added to the network with dynamically assigned cell IDs, then network adaptability improves, but inter-cell interference increases
Solution Approach 1:
The patent implements a feedback mechanism where base stations exchange information about their cell configurations and detect potential interference conditions. When a base station adjusts its cell ID or frequency, it notifies neighboring base stations, which can then adjust their configurations to avoid interference, creating a coordinated interference management system.
Solution Approach 2:
The patent dynamically changes cell configuration parameters (cell ID, carrier frequency, bandwidth) based on real-time network conditions. By adjusting these parameters adaptively, the system can optimize resource allocation while minimizing inter-cell interference through coordinated parameter modification across multiple base stations.
3Quantity of substance
If macro cell and micro cell use different cell IDs to obtain more control channel capacities, then control channel capacity increases, but inter-cell collaboration performance deteriorates
Solution Approach 1:
The patent enables dynamic switching between different cell ID configurations based on network requirements. When inter-cell collaboration is prioritized, macro and micro cells can use the same cell ID; when control channel capacity is prioritized, they can use different cell IDs. This dynamic adaptability allows the system to optimize for different operational scenarios.
Solution Approach 2:
The patent allows flexible modification of cell ID parameters to balance control channel capacity and inter-cell collaboration performance. By dynamically adjusting whether macro and micro cells share or differentiate their cell IDs based on current network conditions, the system can optimize both control channel utilization and collaboration effectiveness.
