Wireless Device Beam-Level Measurement Filtering Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, especially in 5G technologies like New Radio (NR), the existing methods for beam-level measurements are resource-intensive and inefficient, leading to unnecessary power consumption and resource usage due to the need for continuous filtering across multiple beams, even when only some beams are required for measurement reports.
Innovation Solution
A mechanism is introduced to control the initiation and deactivation of additional filtering processes for beam-level measurements, allowing wireless devices to perform filtering only when necessary, based on specific triggering criteria such as cell quality thresholds or event-based conditions, thereby optimizing resource usage and reducing unnecessary filtering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If continuous filtering is performed on all beams, then measurement precision is improved, but use of energy increases and resource usage becomes inefficient
Solution Approach 1:
The patent implements dynamic filtering by introducing triggering criteria (events) that determine when filtering should be performed. The filtering process is activated only when specific conditions are met (e.g., cell quality thresholds, beam quality changes), rather than running continuously. This dynamic approach maintains measurement precision when needed while significantly reducing power consumption during normal operation.
Solution Approach 2:
The patent employs periodic filtering based on event-triggered intervals. Instead of continuous filtering, the system performs filtering periodically when triggering events occur, such as when cell quality changes exceed thresholds or when beam quality metrics indicate potential handover conditions. This periodic action maintains measurement accuracy while minimizing unnecessary processing and energy usage.
2Measurement precision
If filtering is performed on multiple beams simultaneously, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent segments the filtering process by applying it individually to specific beams based on triggering criteria rather than uniformly to all beams. The system divides the beam set into those requiring filtering (triggered beams) and those not requiring filtering, thereby reducing overall device complexity while maintaining precision for critical beams.
Solution Approach 2:
The patent applies local quality by making filtering intensity and application beam-specific. Different beams receive filtering treatment based on their individual characteristics and triggering events. This localized approach ensures high measurement precision for beams that need it while avoiding unnecessary filtering complexity for beams that don't require it.
3Productivity
If beam-level filtering is always performed, then productivity of measurement reporting is improved, but loss of energy increases
Solution Approach 1:
The patent implements dynamic control of filtering based on network conditions and measurement requirements. Filtering is activated only when triggering events indicate that measurement reports are actually needed, such as when handover conditions are met or when beam quality changes significantly. This dynamic approach maintains reporting productivity while eliminating energy waste during stable conditions.
Solution Approach 2:
The system uses self-service by automatically determining when filtering is needed based on pre-configured triggering criteria. The wireless device monitors its own measurement states and autonomously activates or deactivates filtering based on whether reporting conditions are met, without requiring continuous network control signals. This maintains productivity while reducing unnecessary energy consumption.

AI summary
A method performed by wireless device for handling communication in a wireless communication network is provided. The wireless device obtains an indication indicating control, when to initiate and/or when to stop, use of an additional filtering process for measurements on a beam level for including one or more measurements on a beam level in a measurement report. The wireless device applies the additional filtering based on the obtained indication.
