Solution Overview
Problem
Modern wireless communication systems struggle with adapting to dynamic network conditions, user mobility, and interference patterns, lacking real-time, cross-layer coordination across diverse Radio Access Technologies (RATs, such as LTE, 5G NR, Wi-Fi, and satellite links, which hinders ultra-reliable low-latency communication and IoT deployments.

Engineering Contradiction Analysis
1Ease of operation
If base station mediation is used for all data exchanges, then network control is simplified, but latency increases and bottlenecks are introduced
Solution Approach 1:
The patent extracts data exchange functions from centralized base station mediation to distributed edge devices and user equipment. By enabling direct peer-to-peer communication and local data processing at the edge, the system eliminates unnecessary routing through base stations, thereby reducing latency while maintaining network control through distributed intelligence.
Solution Approach 2:
The patent implements dynamic communication architecture where the degree of base station mediation is adjusted based on real-time network conditions, data types, and service requirements. The system dynamically switches between centralized and distributed modes, allowing low-latency direct communication when needed while maintaining simplified control when appropriate.
2Ease of manufacture
If static or semi-static configurations are used, then protocol implementation is simplified, but adaptability to dynamic network conditions deteriorates
Solution Approach 1:
The patent transforms static protocol configurations into dynamic, adaptive parameters that automatically adjust to changing network conditions. Link quality metrics, handover decisions, and resource allocation are continuously optimized based on real-time measurements of signal strength, interference, and traffic patterns, enabling the system to adapt to mobility and environmental changes without complicating the core protocol structure.
Solution Approach 2:
The patent implements comprehensive feedback mechanisms where physical layer measurements and higher-layer performance data feed back into protocol parameter adjustments. This closed-loop control enables automatic adaptation to network conditions through continuous monitoring and optimization of link quality, handover timing, and resource allocation decisions.
3Device complexity
If physical layer optimization is static or partially reactive, then implementation complexity is reduced, but real-time coordination across layers deteriorates
Solution Approach 1:
The patent establishes continuous physical layer optimization through persistent monitoring and adaptive adjustment of transmission parameters. Rather than periodic or event-driven updates, the system maintains continuous coordination between physical and higher layers through ongoing feedback loops, enabling real-time response to changing conditions while managing complexity through integrated control architectures.

AI summary
A wireless communication method and system enabling dynamic multi-path data transmission and reception across heterogeneous radio access networks. The method includes selecting between sequential, concurrent, or redundant multipath transmission strategies based on real-time measurements of link quality parameters, including signal-to-interference-plus-noise ratio (SINR), reference signal received power (RSRP), delay, and spectrum availability. The system further enables adaptive transmission power control, modulation scheme selection, and carrier configuration based on physical layer feedback, minimizing interference and optimizing spectral efficiency. Peer-to-peer communication between terminals is supported without base station mediation, reducing RAN load. Multi-base station connectivity is enabled, allowing terminals to simultaneously transmit through multiple nodes and aggregate at the core network. The architecture supports real-time topology control, dynamic link adaptation, and transmission parameter adjustment based on physical-layer constraints.
