PUCCH Configuration Across Multiple Component Carriers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently configuring and managing physical uplink control channels (PUCCH) across multiple component carriers, leading to inconsistencies and reduced communication flexibility.
Innovation Solution
The proposed solution involves configuring PUCCH resources across multiple component carriers using configuration information, where user equipment (UE) receives and transmits PUCCH communications based on identified resources in different carriers, ensuring consistent and flexible communication by determining appropriate PUCCH resource sets and quantities through indicators and radio resource control signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If PUCCH resources are configured separately for each component carrier, then resource allocation flexibility is improved, but configuration complexity and inconsistency increase
Solution Approach 1:
The PUCCH resource configuration is segmented into common parameters (applied across all component carriers) and carrier-specific parameters (individual to each component carrier). This segmentation allows flexibility in resource allocation while maintaining configuration consistency through the common parameter set.
Solution Approach 2:
A unified PUCCH configuration framework is established that serves multiple component carriers simultaneously. The configuration includes universal parameters that can be applied across different carriers, reducing overall configuration complexity while maintaining the ability to adapt to specific carrier requirements.
2Reliability
If PUCCH repetition is enabled across multiple component carriers, then transmission reliability is improved, but resource management complexity increases
Solution Approach 1:
PUCCH repetitions across multiple component carriers are managed through a unified configuration approach. The same PUCCH resource configuration is applied consistently across carriers, and repetitions are coordinated through shared timing and resource allocation, reducing the complexity of managing multiple independent configurations.
Solution Approach 2:
PUCCH resource configurations are pre-established and configured in advance for multiple component carriers. This preliminary configuration includes predefined repetition patterns, timing relationships, and resource allocations, which simplifies real-time resource management during actual transmissions.
3Reliability
If consistent PUCCH configuration is maintained across component carriers, then system reliability is improved, but adaptability to carrier-specific conditions decreases
Solution Approach 1:
The PUCCH configuration system implements local quality by allowing carrier-specific parameter overrides while maintaining common configuration elements. Each component carrier can have customized parameters (such as frequency offsets or specific resource allocations) while still benefiting from the consistency and reliability of the unified configuration framework.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information identifying one or more first physical uplink control channel (PUCCH) resources in a first component carrier and one or more second PUCCH resources in a second component carrier. The UE may transmit a first one or more PUCCH communications using the one or more first PUCCH resources and a second one or more PUCCH communications using the one or more second PUCCH resources in accordance with the configuration information. Numerous other aspects are described.
