5G Beam Resource Selection for Handover Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G NR wireless communication systems, selecting the optimal beam resource for handover is challenging due to the smaller granularity of beam-level resource allocation, which can result in poor radio quality and unsuccessful access to dedicated RACH resources, necessitating the use of common resources with potentially better quality.
Innovation Solution
The method involves acquiring auxiliary information and resource evaluation information by the terminal device to determine the optimal access resource for handover, using parameters such as Qrxlevmin and Qqualmin values, and offset values to select either dedicated or common beam resources based on quality evaluation parameters or thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If beam-level resource allocation is used for handover, then resource granularity is improved, but radio quality deteriorates
Solution Approach 1:
The patent changes the selection criteria from purely resource availability to a composite evaluation based on multiple parameters including radio quality metrics (RSRP, RSRQ), resource quality indicators, and handover suitability parameters. This allows the system to select beam resources that optimize both granularity and radio quality by evaluating and comparing different beam resources against these multiple parameters before selection.
2Manufacturing precision
If dedicated RACH resources are selected, then resource allocation precision is improved, but access success rate deteriorates
Solution Approach 1:
The patent performs preliminary evaluation and selection of beam resources before the actual handover execution. The terminal device evaluates multiple beam resources in advance, selects the optimal one based on quality metrics, and prepares the selection result before attempting access. This preliminary action ensures that the most suitable resource is chosen, improving access success rate while maintaining allocation precision.
Solution Approach 2:
The patent incorporates feedback mechanisms where the terminal device evaluates the quality of dedicated RACH resources based on measured parameters (RSRP, RSRQ, resource quality indicators) and uses this feedback to make informed selection decisions. The evaluation results feed into the resource selection process, allowing the system to adapt to actual radio conditions and select resources with higher probability of successful access.
