Inter-eNB Carrier Aggregation Activation Decision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cellular networks face challenges in deciding when to implement inter-eNB carrier aggregation, selecting the appropriate technique, and managing resources between base stations, which affects the quality of service and efficiency of data transmission.
Innovation Solution
A method is introduced to decide on the activation of carrier aggregation across first and second base stations based on parameters such as latency, bit rate, mobility state, battery state, and throughput, using a computer program to assess whether inter-base station carrier aggregation is worthwhile and to improve efficiency and power consumption.

Engineering Contradiction Analysis
1Productivity
If inter-eNB carrier aggregation is activated to increase data rate capacity, then the data rate communicated between the network and UE is improved, but the device complexity and resource management burden increases
Solution Approach 1:
The system dynamically changes operational parameters by activating or deactivating carrier aggregation based on throughput thresholds. When throughput exceeds a first threshold, carrier aggregation is activated to increase data rate. When throughput falls below a second threshold, carrier aggregation is deactivated to reduce complexity. This parameter-based control resolves the contradiction by adapting the system state to current performance conditions.
Solution Approach 2:
The patent implements dynamic control of carrier aggregation activation and deactivation based on real-time throughput measurements. The system transitions between different operational states (aggregation active/inactive) according to performance thresholds, allowing the network to adaptively balance data rate requirements against resource management complexity without manual intervention.
2Reliability
If carrier aggregation is activated to improve quality of service, then user performance is enhanced, but the energy consumption and power usage increases
Solution Approach 1:
The system employs periodic evaluation of throughput conditions to determine carrier aggregation activation. By monitoring throughput against defined thresholds at regular intervals, the system activates carrier aggregation only when quality of service requirements justify the additional power consumption, and deactivates it when conditions no longer warrant the extra energy usage, thus resolving the contradiction between service quality and power consumption.
3Quantity of substance
If inter-eNB carrier aggregation is implemented to increase spectrum access, then the data transmission capacity is improved, but the signalling overhead and activation decision complexity increases
Solution Approach 1:
The patent extracts the complex activation decision-making process from manual configuration and implements automated threshold-based control. By defining clear throughput thresholds for activation and deactivation, the system removes the burden of complex signalling and decision-making from network operators, allowing spectrum access to be dynamically optimized through automated rules rather than manual signalling overhead.
