Uplink Control Channel Dynamic Frequency Mapping

The patent segments the frequency domain into multiple control resource sets (CORESETs), each with its own implicit mapping rules. This allows different PDCCH monitoring occasions to be associated with different CORESETs, enabling fine-grained resource allocation while maintaining implicit mapping benefits. The segmentation resolves the contradiction by organizing resources in a structured manner that reduces both signaling overhead and scheduling complexity.

The patent introduces dynamic parameters such as the association between PDCCH monitoring occasions and CORESETs, allowing the implicit mapping relationship to adapt dynamically based on downlink slot configurations. This dynamic approach enables the system to optimize resource allocation in real-time, reducing scheduling complexity while maintaining low signaling overhead through configurable parameters.

By segmenting the frequency domain into multiple CORESETs and associating them with different PDCCH monitoring occasions, the patent creates organized resource groups that can be efficiently utilized. This segmentation prevents resource fragmentation by establishing clear boundaries and allocation rules, thereby improving resource utilization efficiency while maintaining the signaling overhead reduction benefits of implicit mapping.

The patent makes the implicit mapping mechanism universal by applying it across multiple CORESETs and PDCCH monitoring occasions with configurable parameters. This multi-functional approach allows the same implicit mapping principle to serve different resource allocation scenarios, improving overall resource utilization efficiency while keeping signaling overhead low through parameter-based configuration.

The patent applies local quality by using implicit mapping within each CORESET while allowing different CORESETs to have different configurations. This localized approach maintains the simplicity of implicit mapping for individual resource groups while achieving overall dynamic scheduling benefits, thereby improving PUCCH link performance without significantly increasing implementation complexity.

The patent implements partial dynamic scheduling by combining implicit mapping with configurable parameters for CORESET associations. This partial action approach achieves the necessary PUCCH link performance improvement through selective dynamic configuration rather than complete dynamic scheduling, thus reducing implementation complexity and signaling overhead compared to full dynamic scheduling.

The patent introduces dynamics by configuring associations between PDCCH monitoring occasions and CORESETs, allowing the mapping relationship to adapt to different downlink slot configurations. This dynamic configuration maintains implementation simplicity through parameter-based setup while achieving adaptability to dynamic resource mapping scenarios in 5G systems.

The patent uses parameter changes to achieve adaptability, where configurable parameters define the association between PDCCH monitoring occasions and CORESETs. By changing these parameters, the system can adapt to different resource mapping scenarios without changing the fundamental implicit mapping mechanism, thus maintaining implementation simplicity while gaining versatility.
