Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If millimeter wave frequency bands are introduced in the NR phase, then spectrum resources and data rate capacity are improved, but propagation losses increase and network coverage is reduced
Solution Approach 1:
The patent introduces a relay device as an intermediary component between the base station and user equipment. This relay device receives signals from the base station, processes them, and forwards them to user equipment, thereby compensating for the high propagation losses of millimeter wave frequencies and extending effective network coverage without requiring additional spectrum resources
Solution Approach 2:
The relay device is designed to autonomously perform signal processing functions including receiving capability information from the wireless communication device, determining appropriate relay parameters, and self-configuring its operation mode (amplify-and-forward or decode-and-forward) without requiring complex manual configuration, thereby enabling the system to self-adapt to millimeter wave propagation conditions
2Productivity
If millimeter wave frequency bands are introduced, then data rate capacity is improved, but network deployment cost increases
Solution Approach 1:
The relay device is designed with multi-functionality to perform both signal relaying and capability information management. It can operate in multiple modes (amplify-and-forward, decode-and-forward) and handle different types of communication devices, thereby reducing the need for specialized equipment and lowering overall deployment costs while maintaining high data rate capabilities
Solution Approach 2:
The system dynamically changes operational parameters including the relay device's working mode, signal processing parameters, and resource allocation based on real-time channel conditions and device capabilities. This flexibility allows the network to optimize performance for millimeter wave data rates while avoiding costly fixed infrastructure configurations
3Device complexity
If relay device capability information is not reported, then system complexity is reduced, but scheduling efficiency deteriorates
Solution Approach 1:
The relay device performs preliminary actions by proactively reporting its capability information to the base station before actual communication occurs. This advance reporting enables the base station to pre-configure optimal scheduling parameters and resource allocation strategies, thereby improving scheduling efficiency without adding complex real-time decision-making requirements to the system
Solution Approach 2:
The patent implements a feedback mechanism where the relay device reports capability information back to the base station. This feedback loop enables the base station to make informed scheduling decisions tailored to the specific capabilities of each relay device, improving overall system efficiency while maintaining manageable complexity through standardized feedback protocols
