Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional wireless communication structures are used, then system stability is maintained, but communication flexibility and efficiency are limited
Solution Approach 1:
The patent segments the resource management system into multiple independent components: component carrier management units, bandwidth part configuration units, and resource allocation units. Each unit independently manages specific aspects of resource configuration, enabling flexible adaptation without overwhelming system-wide complexity. This segmentation allows the system to handle multiple component carriers and bandwidth parts through modular, manageable units.
Solution Approach 2:
The patent implements dynamic resource allocation where bandwidth parts and component carriers can be activated, deactivated, or reconfigured based on real-time communication needs. The system dynamically adjusts resource configurations across multiple carriers, allowing flexibility in adapting to different service requirements (eMBB, mMTC, URLLC) while maintaining manageable complexity through structured control mechanisms.
2Productivity
If multiple component carriers are managed with detailed resource configurations, then communication efficiency improves, but system complexity increases
Solution Approach 1:
The patent divides resource configuration management across multiple component carriers, with each carrier having its own bandwidth part configurations and resource allocation units. This segmentation enables efficient parallel management of multiple carriers while keeping individual carrier configurations manageable and independent.
Solution Approach 2:
The patent creates universal resource management structures that can be applied across multiple component carriers and different service types. The bandwidth part configuration units and resource allocation mechanisms are designed to handle diverse scenarios (enhanced Mobile BroadBand, massive Machine Type Communication, Ultra Reliable and Low Latency Communication) through a unified framework, improving efficiency without proportionally increasing complexity.
3Adaptability or versatility
If static resource allocation is used, then system simplicity is maintained, but adaptability to different communication scenarios deteriorates
Solution Approach 1:
The patent implements dynamic resource allocation mechanisms where bandwidth parts and component carriers can be flexibly configured and reconfigured based on communication scenario requirements. The system adapts resource allocations for different services (eMBB, mMTC, URLLC) through structured control units that manage activation, deactivation, and parameter adjustments, maintaining ease of operation through organized control procedures.
Solution Approach 2:
The patent utilizes parameter changes in bandwidth part configurations and component carrier settings to adapt to different communication scenarios. By systematically adjusting resource allocation parameters, carrier frequencies, and bandwidth configurations through controlled mechanisms, the system achieves high scenario adaptability while maintaining operational simplicity through structured parameter management.

AI summary
Terminal device receives a SS/PBCH block, a MIB, and a PDCCH. The MIB includes a first MIB payload bit and a second MIB payload bit. The first MIB payload bit is used for indication of a candidate SS/PBCH block index corresponding to the SS/PBCH block A Q′ value is indicated only by the second MIB payload bit. The Q′ value is used for quasi co-location assumption among SS/PBCH blocks.
