Communication System Control Channel Segmentation

The patent segments the control channel functionality by introducing multiple control channels with different reference signal patterns (first control channel with first reference signal pattern, second control channel with second reference signal pattern). This segmentation allows control information to be distributed across multiple channels, preventing control channel blocking while maintaining resource allocation capability across component carriers.

The patent adds a new dimension to control channel design by introducing multiple reference signal patterns (different sequences) for different control channels. This dimensional expansion allows the system to handle multiple control information streams simultaneously, increasing control channel capacity without compromising resource allocation versatility.

The patent applies local quality by assigning specific reference signal patterns to specific control channels based on their functional requirements. The first control channel uses a first reference signal pattern optimized for its purpose, while the second control channel uses a second reference signal pattern suited to its function. This localized optimization increases capacity without uniformly increasing complexity across the entire system.

Instead of using the same reference signal pattern for all control channels (conventional approach), the patent inverts the approach by using different reference signal patterns for different control channels. This inversion resolves the capacity-blocking issue while managing complexity through functional differentiation rather than uniform complexity.
