Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If single slot transmission is used, then transmission speed is maintained, but spectral density is low and power boosting gain is lost
Solution Approach 1:
The transmission block is segmented across multiple time slots, dividing the transmission resource into several parts. This allows the same data to be transmitted over multiple slots with different resource allocations, thereby increasing spectral density and enabling power boosting without requiring a complete redesign of the transmission framework.
Solution Approach 2:
The patent extends transmission from a single time slot to multiple time slots, adding a temporal dimension to the transmission resource allocation. This multi-slot approach enables power boosting by accumulating energy across slots while maintaining the same data transmission goal, thus increasing spectral density without proportionally increasing complexity.
2Reliability
If time domain repetition is used, then reliability is improved, but coding rate increases and CRC padding is excessive for small data packets
Solution Approach 1:
The patent changes the transmission parameters by allocating different resource amounts across multiple slots rather than repeating the same transmission. This allows for lower coding rates in subsequent slots since the receiver can accumulate information from multiple slots, reducing the need for excessive CRC padding while maintaining reliability through diverse resource allocation.
3Power
If multi-slot transmission is configured, then power boosting gain and spectral density are improved, but scheduling and resource allocation complexity increases
Solution Approach 1:
The multi-slot transmission mechanism is designed to serve multiple functions: it enables power boosting, increases spectral density, and provides flexible resource allocation. By creating a universal framework that handles these multiple objectives simultaneously through standardized multi-slot configuration, the patent reduces the need for separate mechanisms for each function, thereby managing complexity more effectively.
4Quantity of substance
If resources are allocated over multiple slots, then spectral density increases, but resource allocation flexibility decreases
Solution Approach 1:
The patent implements dynamic resource allocation across multiple slots, where the amount of resource allocated to each slot can be adjusted based on channel conditions and traffic requirements. This dynamic approach allows the system to maintain high spectral density by utilizing multiple slots while preserving flexibility to adapt resource distribution to changing conditions, thus resolving the contradiction between density and flexibility.

AI summary
The present disclosure proposes configuration for TB processing over multi-slot, particularly Transmission Block over multi-slot (TBoMS) transmission. Specifically, such configuration for TBoMS may relate to at least one of size determination for TBoMS, scheduling for TBoMS transmission, resources determination and allocation for TBoMS transmission, and so on, and corresponding information related to such configuration can be acquired, set or determined appropriately, so that the TB processing over multi-slot can be performed accordingly.
