Solution Overview
Problem
Current communication networks face challenges in integrating heterogeneous wireless communication technologies to provide wider bandwidth and higher data rates, as they often require complex enhancements to maintain compatibility and efficiency across different communication mediums.
Innovation Solution
The proposed solution involves a communication method that aggregates heterogeneous component carriers, such as radio, optical, and acoustic carriers, at the Layer 2 protocol stack or below, allowing for simultaneous use of multiple carriers to increase bandwidth, with base stations and user equipment capable of configuring and switching between different communication technologies based on availability and user capabilities.

Engineering Contradiction Analysis
1Productivity
If heterogeneous component carriers (radio, optical, acoustic) are aggregated to provide wider bandwidth and higher data rates, then communication performance is improved, but system complexity increases due to integration challenges across different communication mediums
Solution Approach 1:
The patent segments the heterogeneous carrier aggregation problem by introducing separate protocol stacks for each carrier type (radio, optical, acoustic) while maintaining a common upper-layer architecture. Each carrier type has its own Layer 2 and Layer 3 protocols tailored to its specific characteristics, allowing independent optimization without forcing a one-size-fits-all approach. This segmentation resolves the contradiction by enabling high data rates through multiple specialized carriers while managing complexity through modular, carrier-specific protocol design rather than a monolithic complex system.
2Area of stationary object
If multiple heterogeneous carriers are integrated simultaneously, then bandwidth is increased, but compatibility maintenance across different communication technologies becomes more difficult
Solution Approach 1:
The patent implements universality through a common Layer 1 (physical layer) architecture that can handle multiple carrier types (radio, optical, acoustic) through a unified interface and resource management mechanism. The Layer 2 and Layer 3 protocols are designed to be carrier-agnostic, providing universal functionality that works across all carrier types. This multi-functionality approach enables the system to aggregate diverse carriers for increased bandwidth while maintaining compatibility through a universal control plane that adapts to each carrier's specific requirements without requiring separate management systems.
3Reliability
If extensive network upgrades are implemented to support heterogeneous carrier aggregation, then communication performance is enhanced, but deployment cost and complexity increase
Solution Approach 1:
The patent employs dynamics by enabling flexible, on-demand configuration of heterogeneous carriers based on network conditions, user requirements, and available resources. The system can dynamically activate or deactivate specific carrier types (radio, optical, acoustic) and adjust their parameters without requiring permanent, rigid network infrastructure changes. This dynamic approach enhances communication performance by optimizing carrier usage in real-time while reducing deployment complexity by allowing gradual, selective implementation rather than requiring comprehensive upfront network upgrades.

AI summary
Communication methods for aggregation of heterogeneous component carriers and communication devices and wireless communication stations using the same methods are proposed. In one embodiment, the proposed communication method is adapted to a wireless communication station and includes aggregating physical channel resources respectively corresponding to heterogeneous access technologies in a Layer 2 or below the Layer 2 in a protocol stack; and communicating with at least one wireless terminal communication device through the physical channel resources respectively corresponding to the heterogeneous access technologies, wherein the physical channel resources respectively corresponding to heterogeneous access technologies are heterogeneous component carriers. The physical channel resources may be heterogeneous component carriers, such as radio component carrier(s), optical component carrier(s), and/or acoustic component carrier(s).
