PUCCH Resource Configuration for Dynamic Repetition and Frequency Hopping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G NR technology faces limitations in dynamically configuring Physical Uplink Control Channel (PUCCH) resources for repetition and frequency hopping, which restricts flexibility and efficiency in PUCCH format configurations, particularly in handling varying communication requirements.
Innovation Solution
The proposed solution involves configuring PUCCH resources with independent repetition and inter-slot frequency hopping configurations, allowing dynamic adjustment through Downlink Control Information (DCI) and MAC-Control Element (MAC-CE), overriding traditional format-based configurations to enhance flexibility and adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If PUCCH format-based repetition and frequency hopping configurations are used, then the system maintains standardized format structures, but the flexibility and adaptability in dynamically configuring PUCCH resources are restricted
Solution Approach 1:
The patent segments the PUCCH configuration by separating format-based configurations from resource-based configurations. The PUCCH resource configuration is divided into independent parameters (repetition factor, frequency hopping, spatial relations) that can be configured separately from the PUCCH format, allowing flexible combination and override without changing the overall format structure.
Solution Approach 2:
The patent introduces dynamic configurability by allowing the PUCCH resource configuration to override the format-based configuration through RRC signaling. This enables the system to dynamically adjust repetition factors, frequency hopping patterns, and spatial relations based on current communication requirements rather than being fixed by format definitions.
2Adaptability or versatility
If independent PUCCH resource configurations are implemented, then dynamic adaptability is improved, but the configuration and control mechanisms become more complex
Solution Approach 1:
The patent implements preliminary configuration through RRC signaling that sets up the PUCCH resource configuration in advance. The gNB pre-configures parameters such as repetition factor, frequency hopping, and spatial relations, which are then activated and controlled dynamically through DCI formats, reducing the need for complex real-time negotiation.
Solution Approach 2:
The patent introduces DCI format as an intermediary between the RRC-configured parameters and the actual PUCCH transmission. The DCI format carries indicators that select and activate specific configurations from the pre-configured set, simplifying the control mechanism while maintaining flexibility.
3Adaptability or versatility
If PUCCH format repetition configurations are used, then format consistency is maintained, but the ability to handle varying communication requirements is limited
Solution Approach 1:
The patent applies local quality by allowing different PUCCH resources configured with the same format to have different repetition factors, frequency hopping patterns, and spatial relations. This enables each resource to be optimized for its specific communication requirement while maintaining format consistency at the structural level.
Solution Approach 2:
The patent enables parameter changes by allowing the PUCCH resource configuration to independently modify key parameters (repetition factor, frequency hopping, spatial relations) without changing the PUCCH format itself. This maintains format reliability while adapting to varying communication requirements through parameter adjustment.

AI summary
The apparatus receives a PUCCH resource configuration associated with a PUCCH resource. The PUCCH resource configuration indicates at least one of a PUCCH resource repetition configuration or a PUCCH resource inter-slot frequency hopping configuration for the PUCCH resource that is independent of PUCCH formats. In addition, the apparatus transmits a PUCCH in the PUCCH resource based on the at least one of the PUCCH resource repetition configuration or the PUCCH resource inter-slot frequency hopping configuration configured in the PUCCH resource configuration. The received PUCCH resource configuration may override a PUCCH format configuration. The apparatus may receive a DCI indicating the PUCCH resource and/or a MAC-CE associated with the PUCCH resource configuration, and may transmit the PUCCH based on the received DCI/MAC-CE.
