Base Station Beam Management for 5G Secondary Carriers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly in 5G networks, unified beam management across multiple carriers can lead to suboptimal beam directions, resulting in poor communication quality and link failures due to varying beam direction requirements across different carriers, especially when terminals have different capabilities and frequency intervals.
Innovation Solution
A method and apparatus for beam management that allows individual beam management on secondary carriers based on the terminal's beam management capability information, determining whether individual or unified beam management is necessary to ensure optimal beam directions and reduce signaling overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If unified beam management is used across multiple carriers, then signaling overhead is reduced and operation is simplified, but beam direction optimality deteriorates leading to poor communication quality and link failures
Solution Approach 1:
The patent segments beam management into two modes: unified beam management for terminals with small frequency intervals (simpler operation) and individual beam management for terminals with large frequency intervals (better reliability). This segmentation allows the system to select the appropriate management mode based on terminal capability information, resolving the contradiction between operational simplicity and communication quality.
2Reliability
If individual beam management is performed on secondary carriers, then beam direction optimality and communication quality are improved, but signaling overhead increases
Solution Approach 1:
The patent changes the beam management parameter (unified vs. individual) based on terminal capability parameters (beam management capability information and frequency interval). By dynamically adjusting the management mode according to terminal-specific parameters, the system achieves optimal communication quality only when necessary, thereby minimizing unnecessary signaling overhead while maintaining reliability where required.
3Reliability
If beam management capability information is collected and processed, then adaptive beam management strategy is achieved improving communication quality, but device complexity increases
Solution Approach 1:
The patent implements a dynamic beam management system that adapts between unified and individual management modes based on real-time terminal capability information. The base station dynamically selects the appropriate management strategy by evaluating terminal beam management capability information, allowing the system to maintain high communication quality while avoiding unnecessary complexity by not always employing the more complex individual management approach.
