Beam Management Framework for Carrier Aggregation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current beam management procedures in 5G cellular networks are inadequate for secondary cells in carrier aggregation scenarios, as they are defined assuming single carrier operations, leading to inefficiencies in beam measurement, reporting, and recovery processes.
Innovation Solution
A method for User Equipment (UE) to perform beam management procedures, including beam measurement, reporting, and recovery for both primary and secondary cells, using predefined conditions and network commands, to enhance reliability and mobility performance in high-frequency deployments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If beam management procedures are defined for single carrier operations, then the procedures are simple to implement, but they are inadequate for secondary cells in carrier aggregation scenarios
Solution Approach 1:
The patent applies universality by defining a unified beam management framework that works for both primary and secondary cells. The network configures beam measurement resources and recovery procedures that can be applied across multiple cell types, allowing the same procedural structure to serve multiple functions in carrier aggregation scenarios.
Solution Approach 2:
The patent segments the beam management procedure into distinct configurable components: beam measurement resource configuration, beam reporting configuration, and beam recovery configuration. Each component can be independently configured for primary and secondary cells, allowing flexible adaptation without requiring complete procedural redesign.
2Reliability
If multiple beam management procedures are performed concurrently for different carriers, then carrier aggregation performance is improved, but the complexity of beam management increases
Solution Approach 1:
The patent applies preliminary action by having the network pre-configure beam measurement resources, reporting configurations, and recovery procedures before carrier aggregation operations begin. This advance configuration establishes a framework that simplifies concurrent beam management across multiple carriers, as the procedural structure is already in place rather than being dynamically created.
Solution Approach 2:
The patent implements feedback mechanisms where the UE reports beam measurement results and beam failure indications to the network. The network uses this feedback to adjust beam configurations and initiate recovery procedures, creating a closed-loop system that manages complexity through intelligent control rather than brute-force procedural multiplication.
3Reliability
If beam measurement and reporting are performed for secondary cells, then mobility performance is improved, but the signaling overhead increases
Solution Approach 1:
The patent merges beam measurement and reporting operations for secondary cells with the existing primary cell beam management framework. By consolidating measurement resource configurations and reporting procedures into a unified structure, the patent reduces redundant signaling while maintaining comprehensive mobility management across all carriers.
