Dynamic Channel Loss Measurement for Shared PUCCH Beam Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for measuring and applying path loss in next-generation mobile communication systems using multiple-input and multiple-output (MIMO) capabilities face challenges due to increased signaling and latency caused by the need to update beam information for multiple physical uplink control channel (PUCCH) resources, particularly in scenarios with a large number of transmission and reception antennas.
Innovation Solution
A method is introduced to dynamically measure and apply path loss resources using beams, allowing common updates across multiple PUCCH resources rather than individual updates, thereby reducing latency and signaling overhead in next-generation mobile communication systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual beam updates are performed for each PUCCH resource, then beam information can be accurately updated for each resource, but signaling overhead and latency increase significantly
Solution Approach 1:
The patent merges multiple individual beam update operations into a single common beam update operation. Instead of updating beam information separately for each PUCCH resource, the system performs one unified beam update that applies to all PUCCH resources simultaneously, thereby reducing signaling overhead and latency while maintaining accurate beam information across all resources
2Reliability
If individual beam updates are performed for each PUCCH resource, then each resource receives targeted update, but signaling overhead increases
Solution Approach 1:
The patent combines multiple beam update signaling operations into a single common beam update signaling operation. This unified approach reduces the total amount of signaling overhead required while ensuring that all PUCCH resources receive the updated beam information, thus maintaining reliability without increasing complexity
3Reliability
If multiple MAC CEs are transmitted to update beam information for all PUCCH resources, then complete beam update is achieved, but latency and signaling overhead increase
Solution Approach 1:
The patent merges multiple separate beam update operations into a single efficient operation. Instead of transmitting multiple MAC CEs to update beam information for each PUCCH resource individually, the system performs one common beam update operation that simultaneously updates all PUCCH resources, achieving complete beam update with improved efficiency and reduced latency
