Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single technology framework is used to handle eMBB, mMTC, and URLLC scenarios, then system simplicity is maintained, but communication flexibility and efficiency are limited
Solution Approach 1:
The patent segments the communication system into multiple independent technology frameworks, each optimized for specific scenarios (eMBB, mMTC, URLLC). This allows each framework to be tailored independently, improving adaptability without requiring a single complex unified framework. The segmentation enables selective deployment and independent optimization of each scenario-specific framework.
Solution Approach 2:
The patent creates a multi-functional system architecture that can operate in different technology frameworks depending on the scenario requirements. The system is designed to be universal by supporting multiple frameworks (NR, LTE, NR-LTE) and can dynamically select or combine them based on whether the requirement is eMBB, mMTC, or URLLC, thus achieving versatility without forcing a single complex framework.
2Productivity
If traditional communication structures are used, then system simplicity is maintained, but communication efficiency is limited
Solution Approach 1:
The patent implements dynamic communication structures that can adapt and change based on scenario requirements. The system dynamically selects appropriate technology frameworks (NR for eMBB, LTE for mMTC, NR-LTE for URLLC) and adjusts communication parameters, resource allocation, and protocol stacks in real-time, thereby improving communication efficiency while managing complexity through dynamic adaptation rather than static complex structures.
Solution Approach 2:
The patent utilizes parameter changes to optimize communication efficiency for different scenarios. By adjusting key parameters such as numerology (subcarrier spacing, cyclic prefix length), resource block allocation, and modulation schemes according to the specific requirements of eMBB, mMTC, or URLLC, the system achieves high efficiency without requiring fundamentally complex structural changes.
3Productivity
If resource allocation is optimized for specific scenarios, then communication efficiency improves, but system complexity increases
Solution Approach 1:
The patent applies local quality by optimizing resource allocation specifically for each scenario (eMBB, mMTC, URLLC) rather than using a uniform approach. Each scenario receives tailored resource allocation strategies: eMBB gets bandwidth-intensive resources, mMTC gets connection-oriented resources, and URLLC gets low-latency resources. This localized optimization improves efficiency while managing complexity by confining scenario-specific complexity to individual resource management modules.
Solution Approach 2:
The patent implements preliminary action by pre-configuring scenario-specific resource allocation patterns and parameter sets. The system prepares optimized resource allocation schemes in advance for each scenario type, so when a scenario is detected, the pre-configured resources can be immediately allocated without complex real-time calculations, thereby improving efficiency while controlling management complexity through advance preparation.

AI summary
Terminal device initiates a COT-u at the beginning of an FFP-u after the channel is sensed to be idle and transmit an uplink transmission burst within the COT-u. In a case that the COT-u overlaps with a sensing slot for initiating an FFP-g with the one or more SS/PBCH blocks, the COT-u is terminated before the sensing slot. In a case that the COT-u does not overlap with the sensing slot, the COT-u is terminated after the sensing slot.
