Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the network supports a wide range of devices with diverse traffic profiles, then the adaptability and versatility of the network is improved, but the device complexity and network configuration complexity increases
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting radio resource allocation parameters based on device capabilities and traffic profiles. The system modifies parameters such as modulation schemes, coding rates, and resource block assignments to optimize performance for different device types (URLLC, eMBB, mMTC) without requiring complex manual network reconfiguration.
Solution Approach 2:
The patent implements dynamics through adaptive resource scheduling that responds to real-time device conditions and traffic requirements. The network dynamically allocates radio resources based on current device capabilities, channel conditions, and service requirements, enabling flexible support for diverse traffic profiles while maintaining manageable system complexity through automated decision-making.
2Reliability
If the network provides high reliability and low latency for URLLC services, then the reliability parameter is improved, but the available radio resources and capacity for other services decreases
Solution Approach 1:
The patent applies segmentation by dividing the radio resource allocation into separate mechanisms for different service types. URLLC resources are allocated with guaranteed reliability through dedicated time slots and priority-based scheduling, while other services (eMBB, mMTC) utilize remaining resources. This segmentation ensures URLLC reliability is maintained while optimizing overall radio resource utilization efficiency through independent management of different service classes.
Solution Approach 2:
The patent implements preliminary action through advance resource reservation and pre-configured scheduling for URLLC services. The network pre-allocates reliable transmission resources and establishes low-latency pathways before actual data transmission occurs, ensuring reliability guarantees are met without requiring reactive resource allocation that would reduce overall productivity.
3Productivity
If the network supports high capacity for eMBB services, then the productivity and data rate are improved, but the latency increases and reliability for time-sensitive services decreases
Solution Approach 1:
The patent applies segmentation by separating eMBB high-capacity transmission from URLLC time-sensitive transmission in the time-domain and resource allocation. eMBB services utilize available capacity during designated periods without interfering with URLLC latency requirements, while URLLC services receive guaranteed low-latency resources. This segmentation enables high eMBB productivity to coexist with low URLLC latency through independent resource management.
Solution Approach 2:
The patent implements periodic action through structured time-division multiplexing that allocates specific periodic time slots for URLLC services to maintain low latency, while allowing eMBB services to utilize remaining periods for high-capacity数据传输. This periodic allocation pattern ensures that time-sensitive services receive regular low-latency transmission opportunities without compromising overall network productivity.
4Reliability
If feedback signals are transmitted in dedicated radio resources, then the reliability of feedback transmission is improved, but the overall radio resource utilization efficiency decreases
Solution Approach 1:
The patent applies merging by combining feedback signal transmission with uplink data channels. Instead of dedicating separate resources for feedback, the system multiplexes feedback information onto existing uplink resources, thereby improving resource utilization efficiency while maintaining feedback reliability through proper encoding and signal processing techniques that ensure accurate transmission without requiring additional dedicated resources.
