Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing configuration of physical uplink control channel (PUCCH) resources for transmitting HARQ-ACK codebooks in 5G communications systems cannot meet the diverse requirements of different service types, such as eMBB and URLLC, affecting communication performance.
Innovation Solution
A method to configure PUCCH resources for multiple HARQ-ACK codebooks, allowing each codebook to correspond to different service types or priorities, enabling tailored resource allocation based on specific requirements for latency and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single PUCCH resource configuration is used for all HARQ-ACK codebooks, then the device complexity is reduced, but the adaptability to different service types deteriorates
Solution Approach 1:
The patent divides the PUCCH resource configuration into separate configurations for different HARQ-ACK codebooks. Each codebook (e.g., first HARQ-ACK codebook for eMBB services, second HARQ-ACK codebook for URLLC services) is assigned its own dedicated PUCCH resource configuration, allowing service-specific optimization without affecting other services.
Solution Approach 2:
The patent applies different PUCCH resource configuration parameters to different codebooks based on their specific service requirements. For example, URLLC codebooks receive configurations optimized for low latency and high reliability, while eMBB codebooks receive configurations optimized for throughput, ensuring each codebook has the quality characteristics needed for its service type.
2Adaptability or versatility
If different PUCCH resource configurations are provided for different HARQ-ACK codebooks, then the adaptability to different service types is improved, but the device complexity increases
Solution Approach 1:
The patent performs preliminary configuration of different PUCCH resource settings for different codebooks before actual communication occurs. The network side device pre-configures and signals the terminal about which PUCCH resources correspond to which codebooks, so that during operation the terminal can directly use the appropriate pre-configured resources without dynamic complexity.
Solution Approach 2:
The patent introduces a correspondence relationship (mapping) between HARQ-ACK codebooks and PUCCH resource configurations as an intermediary structure. This mapping mechanism allows the system to manage multiple configurations in an organized way, where the correspondence relationship acts as a mediator that simplifies the association between codebooks and their respective resources.
3Reliability
If a unified PUCCH resource is used for multiple service types, then the ease of operation is improved, but the communication performance for specific service requirements deteriorates
Solution Approach 1:
The patent makes the PUCCH resource selection dynamic by allowing the terminal to determine which PUCCH resource to use based on which HARQ-ACK codebook needs to be transmitted. The terminal dynamically selects the appropriate pre-configured PUCCH resource according to the service type and codebook association, achieving both performance optimization and operational clarity.
