Communications Device Beam Selection Offset
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communications networks face challenges in managing mobility and selecting the most suitable infrastructure equipment due to the need to balance the number of available beams and their quality, leading to frequent handovers and increased traffic, especially in scenarios with diverse data traffic profiles and devices.
Innovation Solution
A communications device is configured to detect and evaluate beams from multiple infrastructure equipment cells, applying an offset or weighting factor to measurements based on the number of beams received to bias the selection towards cells with a suitable balance of beams and quality, reducing unnecessary handovers and improving network efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communications device selects cells based solely on beam quality measurements, then connection quality is improved, but frequent handovers occur due to cells with few beams having temporarily strong beam quality
Solution Approach 1:
The patent modifies the cell selection parameter by introducing a beam count component that changes the evaluation criterion from purely beam quality-based to a composite metric incorporating both beam quality and beam quantity. This parameter change prevents selection of cells with few beams even when their beam quality is temporarily strong, thereby reducing frequent handovers while maintaining connection quality.
Solution Approach 2:
The patent applies a biasing mechanism that预先 compensates for the potential instability of cells with few beams. By adjusting the cell evaluation metric in advance to favor cells with more beams, the system cushions against future handover instability before it occurs, reducing frequent handovers while maintaining reliable connections.
2Adaptability or versatility
If the network supports diverse data traffic profiles with different latency tolerances, then device versatility is improved, but mobility management complexity increases
Solution Approach 1:
The patent introduces beam count as an additional parameter in cell evaluation, transforming the mobility management decision-making process from simple signal strength comparison to a multi-parameter assessment. This enables the system to handle diverse device requirements more effectively while providing a systematic approach that reduces management complexity through standardized evaluation criteria.
