Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems fail to accurately determine channel busy ratio (CBR) and channel occupancy ratio (CR) metrics for beamformed communication due to the lack of consideration of neighboring beams, leading to potential interference and inefficient resource allocation.
Innovation Solution
Techniques are developed to determine channel ratio metrics by taking into account neighboring beams during CBR and CR calculations, ensuring more accurate assessments for beamformed communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional CBR and CR metrics are used without considering neighboring beams, then the calculation complexity is low, but the measurement precision deteriorates leading to inaccurate channel state assessment
Solution Approach 1:
The patent segments the beam measurement process by introducing beam group IDs that categorize neighboring beams into distinct groups. This segmentation allows the UE to selectively measure and report CBR and CR metrics for specific beam groups rather than all beams, improving measurement precision while managing complexity through organized categorization of beam relationships
Solution Approach 2:
The patent adds a new dimension to beam measurement by introducing angular separation thresholds and beam group IDs alongside traditional beam identifiers. This dimensional expansion enables the system to differentiate between neighboring beams based on spatial relationships, allowing more accurate CBR and CR assessments without proportionally increasing overall system complexity
2Object-affected harmful factors
If beam-specific CBR and CR metrics are determined considering angular separation, then interference reduction is improved, but the difficulty of detecting and measuring increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring angular separation thresholds and beam group IDs through higher-layer signaling before actual CBR and CR measurements are performed. This pre-establishment of measurement criteria simplifies the real-time detection process, as UEs only need to compare measured angular separations against pre-defined thresholds rather than performing complex real-time calculations
Solution Approach 2:
The patent introduces beam group IDs as an intermediary element that mediates between raw angular separation measurements and final CBR/CR metric calculations. This intermediary categorization layer simplifies the measurement process by grouping beams with similar interference characteristics, reducing the computational burden while maintaining interference assessment accuracy
3Productivity
If channel ratio metrics are determined without beam grouping, then the signaling overhead is low, but the resource allocation efficiency deteriorates
Solution Approach 1:
The patent merges multiple beam measurements into beam group-level CBR and CR metrics by aggregating measurements from beams sharing the same beam group ID. This merging approach improves resource allocation efficiency by providing representative channel state information for groups of beams without transmitting separate metrics for each individual beam, thereby reducing signaling overhead while maintaining allocation accuracy
Solution Approach 2:
The patent applies partial action by selectively reporting CBR and CR metrics only for beam groups that exceed certain thresholds or are relevant to current communication needs. This partial reporting approach reduces signaling overhead by omitting redundant information while maintaining sufficient accuracy for resource allocation decisions, achieving efficiency without excessive information transmission

AI summary
Certain aspects of the present disclosure provide techniques for determining and using channel ratio metrics for beamformed communication. A method that may be performed by a user equipment (UE) includes selecting a first beam of a plurality of beams for determining one or more channel ratio metrics, determining the one or more channel ratio metrics for the first beam, wherein determining the one or more channel ratio metrics is based, at least in part, on an angular separation between the first beam and one or more neighboring beams of the plurality of beams, and transmitting signaling via the first beam based on the one or more channel ratio metrics.
