1Reliability
If time domain multiplexing (TDM) interference mitigation schemes are used to schedule data transmissions, then signal quality is improved, but data throughput is reduced
Solution Approach 1:
The patent combines multiple TDM interference mitigation schemes from different wireless networks (e.g., LTE and Wi-Fi) into a synchronized framework. By merging the scheduling mechanisms and aligning their time intervals, the system achieves coordinated interference reduction across networks, improving signal quality while minimizing the cumulative impact on data throughput through optimized resource allocation.
2Object-affected harmful factors
If interference mitigation schemes are applied across multiple heterogeneous networks, then interference is reduced, but data throughput loss increases
Solution Approach 1:
The patent implements dynamic synchronization of TDM schemes across heterogeneous networks by adjusting time interval parameters based on network conditions, traffic patterns, and interference levels. The system continuously adapts the scheduling parameters of different networks to achieve optimal interference mitigation while minimizing throughput loss, rather than using fixed static schedules.
Solution Approach 2:
The system modifies key parameters of the TDM schemes, such as time interval durations, scheduling periods, and offset values, to optimize the balance between interference reduction and throughput maintenance. By dynamically changing these parameters based on real-time network conditions, the system achieves effective interference mitigation across heterogeneous networks while minimizing the impact on data throughput.
