Adaptive Frame Structure With Filtered OFDM

The patent implements dynamic frame structure adaptation by allowing the base station to select from multiple predefined frame formats (e.g., different subcarrier spacings, cyclic prefix lengths, symbol durations, and TTI lengths) and switch between them based on real-time channel conditions and traffic type requirements. This dynamic switching capability enables the system to adapt to diverse traffic types while managing complexity through predefined options rather than fully configurable parameters.

The patent changes key frame structure parameters including subcarrier spacing, cyclic prefix length, symbol duration, and TTI length to match different traffic requirements. By modifying these parameters across different frame formats, the system can optimize performance for various traffic types (e.g., latency-sensitive vs. bandwidth-sensitive) without requiring complete system redesign.

The patent segments the frame structure configuration into multiple predefined frame formats, each optimized for specific traffic types or channel conditions. Instead of requiring the device to manage all possible parameter combinations, the system divides the configuration space into discrete, manageable formats (e.g., Format 1 for low latency, Format 2 for high spectral efficiency), reducing the complexity of configuration management while maintaining high spectral efficiency.

The patent creates a universal frame structure framework that can accommodate multiple frame formats through a single base station and user equipment implementation. The multi-functional design allows the same physical layer infrastructure to support diverse traffic types by simply changing the selected frame format, eliminating the need for separate hardware configurations for each traffic type.
