Engineering Contradiction Analysis
1Productivity
If existing wireless communication systems use fixed transmission management protocols, then system simplicity is maintained, but network performance optimization is insufficient in heterogeneous networks with varying device capabilities and traffic loads
Solution Approach 1:
The patent implements dynamic transmission management by allowing the network to adaptively adjust transmission parameters such as modulation and coding scheme (MCS), resource allocation, and power control based on real-time channel conditions, device capabilities, and traffic characteristics. This dynamic adaptation enables the system to optimize network performance across heterogeneous networks while managing complexity through automated decision-making algorithms that respond to varying operational conditions.
Solution Approach 2:
The system changes transmission parameters dynamically based on network conditions, including adjusting MCS indices, bandwidth parts (BWPs), and resource block allocations. By modifying these parameters in response to measured channel quality indicators (CQI), signal strength, and device capability reports, the system achieves optimized performance across diverse network scenarios without requiring complex manual configuration.
2Productivity
If the system uses fixed resource allocation strategies, then implementation simplicity is maintained, but data transmission efficiency is suboptimal under varying network conditions
Solution Approach 1:
The patent employs feedback mechanisms where wireless devices report channel quality indicators, signal strength, and capability information to the network. The network uses this feedback to dynamically adjust resource allocation decisions, selecting optimal modulation schemes, allocating appropriate resource blocks, and adjusting power levels. This closed-loop feedback system enables continuous optimization of data transmission efficiency while adapting to changing network conditions and device capabilities.
Solution Approach 2:
The system performs preliminary actions by pre-configuring multiple bandwidth parts (BWPs) and modulation and coding schemes (MCS) before actual data transmission occurs. When channel conditions change, the system can quickly switch between pre-configured options without delay, enabling rapid adaptation to varying network conditions while maintaining high transmission efficiency.
3Adaptability or versatility
If the system supports multiple device capabilities and traffic types, then network versatility is improved, but transmission management complexity increases
Solution Approach 1:
The patent implements a universal transmission management framework that handles multiple device types and traffic characteristics through a single integrated system. The network uses unified protocols and algorithms that can accommodate diverse devices ranging from smartphones to IoT sensors, managing different traffic types including voice, video, and data through consistent resource allocation mechanisms. This multi-functional approach enables the system to support heterogeneous networks without proportionally increasing management complexity.

AI summary
A wireless device receives one or more first messages comprising one or more first configuration parameters indicating one or more frequency bands associated with a no transmission zone (NTZ), wherein transmission by the wireless device via the one or more frequency bands is restricted within the NTZ. The wireless device receives one or more second messages comprising one or more second configuration parameters indicating a normal uplink (NUL) carrier of a cell, and a supplementary uplink (SUL) carrier of the cell, and selects, for a random access procedure in the cell, an uplink (UL) carrier among the SUL carrier and the NUL carrier, based on a frequency band of the UL carrier not being one of the one or more frequency bands; and the wireless device being within the NTZ.
