Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If transport block sizes are fixed or statically configured, then device complexity is reduced and ease of operation is improved, but data transmission efficiency deteriorates and productivity decreases
Solution Approach 1:
The patent implements dynamic TBS adjustment mechanisms where the base station continuously monitors network conditions, device capabilities, and traffic characteristics to adaptively select optimal TBS values. This dynamic approach replaces static configuration with real-time adjustment, directly improving data transmission efficiency while the automation of this process manages the complexity through standardized procedures
Solution Approach 2:
The patent changes the TBS parameter based on multiple factors including device capabilities, traffic load, channel conditions, and QoS requirements. By making TBS a variable parameter rather than a fixed value, the system optimizes transmission efficiency for different scenarios while using standardized parameter adjustment rules to manage complexity
2Productivity
If adaptive TBS adjustment is implemented, then data transmission efficiency is improved and productivity increases, but device complexity increases and ease of operation deteriorates
Solution Approach 1:
The patent implements self-service mechanisms where the base station automatically monitors network conditions, evaluates device capabilities, and adjusts TBS without manual intervention. This automation improves transmission efficiency while shielding operators from the complexity of TBS management through intelligent self-configuration
Solution Approach 2:
The patent employs feedback loops where transmission performance is continuously monitored and used to adjust TBS values. This closed-loop control automatically optimizes efficiency while the standardized feedback processing mechanisms manage operational complexity through consistent decision-making algorithms
3Productivity
If larger transport block sizes are used, then productivity increases and data transmission efficiency improves, but reliability decreases due to higher error rates in heterogeneous environments
Solution Approach 1:
The patent dynamically adjusts TBS parameters based on real-time channel quality indicators and device capability assessments. By changing TBS according to actual transmission conditions rather than using fixed large values, the system achieves high productivity when conditions permit while maintaining reliability through adaptive reduction of TBS when channel quality degrades
Solution Approach 2:
The patent implements dynamic TBS selection that adapts to varying channel conditions, device capabilities, and traffic requirements. This dynamic approach allows the system to use larger TBS for high-quality channels to maximize productivity while automatically switching to smaller TBS for poor conditions to maintain reliability

AI summary
A wireless device receives one or more configuration parameters comprising a parameter indicating that a retransmission of a transport block (TB) with a different TB size (TBS) than an initial transmission of the TB are new transmissions. The wireless device receives a first TB with a first TBS. The wireless device receives a retransmission of the first TB with a second TBS based on combining the first TB with the retransmission of the first TB in response to the first TBS being the same as the second TBS or decoding the retransmission of the first TB as a new transmission in response to the first TBS being different from the second TBS.
