Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks, particularly 4G, fail to ensure reliable and low-latency connectivity in areas with poor coverage or high interference, limiting their application in Ultra-Reliably/Critical Machine Type Communication (U-MTC) scenarios, which require ultra-reliability and ultralow delay.
Innovation Solution
A method and system for transmitting control plane uplink signaling using multi-RAT hybrid networking, where the wireless communication network determines and configures the appropriate transmission mode based on diversity capability information to implement Ultra-Reliable Communication (URC) by switching between different Radio Access Technologies (RATs) for enhanced reliability and reduced delay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single Radio Access Technology (RAT) is used for transmission, then the system complexity is low, but the reliability and coverage in poor areas deteriorate
Solution Approach 1:
The patent combines multiple Radio Access Technologies (RATs) into a unified transmission system. The network device establishes connections with terminal devices through different RATs (e.g., LTE and NR) simultaneously, merging their capabilities to achieve higher reliability and coverage than any single RAT could provide alone.
Solution Approach 2:
The network device is designed to support multiple RATs universally, enabling it to adapt to different transmission scenarios. The system can selectively use appropriate RATs based on service requirements, terminal capabilities, and network conditions, making the transmission system versatile and adaptable to various reliability needs.
2Reliability
If multiple Radio Access Technologies (RATs) are used for transmission, then the reliability and coverage improve, but the system complexity increases
Solution Approach 1:
The patent implements dynamic RAT selection and configuration. The network device can dynamically adjust which RATs are used for transmission based on real-time network conditions, terminal capabilities, and service requirements. This dynamic adaptation allows the system to maintain high reliability while managing complexity through intelligent, context-aware decision-making.
Solution Approach 2:
The system changes transmission parameters such as selecting different RATs, adjusting modulation schemes, and modifying resource allocation based on network conditions. By dynamically changing these parameters, the system optimizes reliability for each transmission scenario while avoiding the need for permanently complex configurations.
3Adaptability or versatility
If traditional network architecture is used, then the device complexity is low, but the adaptability to different service requirements deteriorates
Solution Approach 1:
The patent segments the network architecture into functional modules including network devices, terminal devices, and core network functions. Each segment can be independently configured and optimized for specific service requirements. This modular segmentation enables flexible adaptation to different services (e.g., eMBB, uRLLC, mMTC) while managing overall system complexity through clear functional boundaries.
Solution Approach 2:
The network architecture implements dynamic configuration capabilities where network devices can be dynamically deployed, configured, and managed based on service needs. The system can adaptively allocate resources, select appropriate RATs, and reconfigure transmission parameters to meet varying service requirements, transforming a static architecture into a dynamic, service-adaptive system.
