RIS Beam Grouping for Faster Millimeter-Wave Beam Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In millimeter wave communication systems, the deployment of multiple reconfigurable intelligent surfaces (RIS) for beam management results in low efficiency and affects communication quality due to the need for individual beam management of each RIS, which is time-consuming and prone to non-timely adjustments.
Innovation Solution
A method is introduced to group multiple relay devices into beam management groups based on preset criteria, allowing simultaneous beam management and configuration within each group, improving efficiency and ensuring communication quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If individual beam management is performed on each reconfigurable intelligent surface, then beam management precision is maintained, but beam management efficiency deteriorates and communication quality is affected
Solution Approach 1:
The patent merges multiple reconfigurable intelligent surfaces into beam management groups, allowing the base station to perform beam management on groups of RISs simultaneously rather than individually. This combining approach increases beam management efficiency while maintaining communication quality through coordinated group management.
Solution Approach 2:
The patent segments the RISs into multiple beam management groups based on spatial distribution and management requirements. Each group can be managed independently, allowing parallel processing and improving overall efficiency while maintaining the reliability of individual RIS connections through dedicated group management.
2Area of stationary object
If multiple reconfigurable intelligent surfaces are deployed within coverage range, then coverage capability is improved, but beam management complexity increases and efficiency decreases
Solution Approach 1:
The patent combines multiple RISs into beam management groups, which simplifies the management process by treating groups as single units. This reduces the complexity of managing individual RISs while maintaining extensive coverage capability through coordinated group operation.
Solution Approach 2:
The patent creates a universal beam management approach that applies to all RISs within a group through standardized group management procedures. This multi-functional framework allows the base station to manage multiple RISs using the same group-based methodology, reducing complexity while expanding coverage.
3Loss of time
If sequential beam management is performed on each reconfigurable intelligent surface, then management precision is maintained, but time consumption increases and timely adjustments are prevented
Solution Approach 1:
The patent merges multiple RISs into beam management groups that can be managed simultaneously in parallel. This eliminates sequential processing time while maintaining precision through coordinated group management, allowing timely adjustments across all RISs without sacrificing measurement accuracy.
Solution Approach 2:
The patent enables continuous beam management operations on multiple RISs simultaneously through group-based parallel processing. This continuous action eliminates idle time between sequential operations while maintaining precision through ongoing coordinated management of all RISs in the group.
