Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of PRBs for PUCCH resources is configured based on the first size of CRC bits, then the transmission of UCI payload is reliable, but the resource allocation is inefficient when using a second size of CRC bits
Solution Approach 1:
The patent applies dynamics by making the CRC bit size configurable rather than fixed. The system can dynamically select between first size and second size of CRC bits based on the UCI payload size, allowing the PUCCH resource configuration to adapt to different transmission scenarios and optimize both reliability and efficiency.
Solution Approach 2:
The patent changes the parameter of CRC bit size from a fixed value to a variable that can be selected based on conditions. By configuring different CRC bit sizes (first size for smaller payloads, second size for larger payloads), the system optimizes the balance between transmission reliability and resource allocation efficiency for different UCI payload scenarios.
2Ease of operation
If a fixed number of PRBs is allocated for PUCCH, then the resource allocation is simple, but it cannot adapt to different UCI payload sizes and CRC bit configurations
Solution Approach 1:
The patent transforms the static PRB allocation into a dynamic configuration system. The number of PRBs for PUCCH resources is determined based on both the UCI payload size and the selected CRC bit size, enabling the system to adapt resource allocation to different transmission requirements while maintaining clear configuration rules.
Solution Approach 2:
The patent introduces parameter-based resource allocation where the number of PRBs varies according to the configured CRC bit size and UCI payload size. This allows the system to maintain operational simplicity through standardized configuration procedures while achieving adaptability to different payload and CRC bit size combinations.
3Quantity of substance
If more PRBs are allocated for PUCCH resources, then the uplink transmission capacity increases, but the resource utilization efficiency decreases
Solution Approach 1:
The patent optimizes resource utilization by configuring the number of PRBs based on the actual transmission needs determined by UCI payload size and CRC bit size. This parameter-based allocation ensures that sufficient resources are allocated to maintain transmission capacity while avoiding excessive resource allocation that would reduce utilization efficiency.
Solution Approach 2:
The patent applies partial action by allocating PRBs proportionally to the actual transmission requirements. Rather than always allocating maximum resources, the system allocates the appropriate number of PRBs based on the configured CRC bit size and payload size, achieving efficient resource utilization while maintaining adequate transmission capacity.
Data Source
AI summary
A terminal apparatus includes a transmitter configured to transmit a UCI payload with CRC bits by using a PUCCH, wherein a size of the CRC bits added to the UCI payload is a first size, and a number of PRBs of a resource of the PUCCH is given based on a second size of the CRC bits.
