Modified Subframe Structure for TDD Interference Mitigation

The patent applies preliminary action by inserting a guard period (GP) before dynamic subframe configuration switching. This guard period allows neighboring cells to synchronize their switching actions, preventing simultaneous transmission conflicts that cause interference. The GP is configured in advance based on cell distance and propagation delay, ensuring that when dynamic switching occurs, cells are coordinated and interference is minimized while traffic adaptation capability is maintained.

The patent applies dynamics by making the guard period configuration adaptive rather than fixed. The GP length and positioning are dynamically adjusted based on cell distance, propagation delay, and traffic conditions. This allows the system to minimize GP overhead in scenarios where interference risk is low while providing sufficient protection when cells are close or traffic patterns require frequent switching, thus balancing interference reduction with communication efficiency.

The patent applies self-service by enabling each cell to autonomously determine its guard period configuration based on locally measurable parameters such as cell distance and propagation delay. Rather than requiring complex centralized coordination or extensive signaling between cells, each cell independently calculates and configures its GP, simplifying the overall system while achieving effective interference mitigation through distance-aware configuration.
