Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beam management procedures are implemented in 5G NR FR2 systems, then communication reliability is improved, but system complexity increases
Solution Approach 1:
The patent segments beam management by introducing group IDs that categorize PUCCH resources into multiple groups. This segmentation allows the system to manage beam failures and updates in a structured manner, improving reliability while maintaining manageable complexity through organized resource grouping.
Solution Approach 2:
The patent implements preliminary action by configuring multiple PUCCH resource groups and their associated group IDs in advance through RRC signaling. This pre-configuration enables rapid beam failure recovery without real-time complex decision-making, enhancing reliability while reducing operational complexity.
2Productivity
If PUCCH resources are updated frequently for beam management, then communication efficiency is improved, but signaling overhead increases
Solution Approach 1:
The patent merges multiple PUCCH resources under common group IDs, allowing MAC CE updates to efficiently manage multiple resources simultaneously. This merging reduces the number of separate signaling operations needed, improving communication efficiency while minimizing signaling overhead.
Solution Approach 2:
The patent introduces group IDs as intermediaries between RRC configuration and MAC CE updates. This intermediary layer enables efficient resource management by allowing MAC CE to reference groups of resources rather than individual resources, reducing signaling overhead while maintaining efficient updates.
3Adaptability or versatility
If multiple PUCCH resource groups are configured for beam failure recovery, then system adaptability is improved, but device complexity increases
Solution Approach 1:
The patent segments PUCCH resources into multiple groups identified by group IDs, enabling the system to adapt to different beam failure scenarios. This segmentation provides adaptability through diverse resource options while managing device complexity through systematic organization and clear identification protocols.

AI summary
Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for Fifth Generation New Radio (5G NR) frequency range two (FR2) based communications beam management. The UE may configure, via communications with a base station, serving the UE, a group ID for PUCCH resources within a group of PUCCHs, e.g., for FR2 based communications. The UE may receive, from the base station, an update to one or more PUCCH resources within the group of PUCCHs via a medium access control (MAC) control element (CE) that may include one of a resource ID indicating an update to a PUCCH resource or the group ID to update the group of PUCCH resources. The UE may update, based on the MAC-CE, the one or more PUCCH resources within the group of PUCCHs.
