Frequency Spectrum Aggregation for Multi-System Data Transmission

The patent divides the aggregated frequency spectrum into multiple component carriers, each corresponding to a different system with its own timing relationship characteristics. The terminal device processes each component carrier separately according to its specific system timing, rather than treating the aggregated spectrum as a single unified resource. This segmentation approach enables efficient utilization of multiple frequency spectrums while managing complexity through modular processing of individual carriers.

The patent applies different timing relationship rules to different component carriers within the aggregated frequency spectrum. Each component carrier maintains its own system-specific timing characteristics (such as TDD uplink-downlink configurations or FDD timing), and the terminal device applies the appropriate timing relationship locally to each carrier based on its system type. This local quality approach preserves the integrity of each system's timing requirements while enabling efficient data transmission across the aggregated spectrum.
