Beam Failure Detection Timer and Counter Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current beam failure detection methods in 5G systems suffer from low accuracy due to the use of a single timer and counter for all beams, leading to misjudgment of available beams as unavailable, especially in high-frequency bands where signal propagation is more prone to interruption.
Innovation Solution
Configuring a timer and counter specifically for each target beam or Bandwidth Part (BWP) to improve accuracy in beam failure detection, allowing for independent monitoring and reporting of beam failure instances, thereby reducing resource wastage and enhancing detection precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single timer and counter are used for all beams, then device complexity is reduced, but beam failure detection precision deteriorates
Solution Approach 1:
The patent divides the beam failure detection mechanism into separate timers and counters for each beam or BWP. Instead of using a single shared timer and counter for all beams, the system configures dedicated timing resources for each beam, allowing independent detection and avoiding misjudgment between different beams.
Solution Approach 2:
The patent applies local quality by making each beam's detection parameters specific to that beam's conditions. Each beam can have its own timer and counter configured according to its specific requirements, rather than applying a uniform configuration across all beams, thereby improving detection accuracy for each individual beam.
2Adaptability or versatility
If beam failure detection is performed for all beams using a single counter, then detection coverage is improved, but detection accuracy deteriorates due to false accumulation
Solution Approach 1:
The patent segments the counting function by creating separate counters for each beam or BWP. This ensures that beam failure instances are counted independently for each beam, preventing false accumulation from other beams and improving the accuracy of failure instance detection for each specific beam.
3Loss of energy
If a single timer is used for all beams, then resource utilization is reduced, but beam-specific detection capability is lost
Solution Approach 1:
The patent segments timing resources by allocating separate timers to different beams or BWPs. This allows the system to maintain beam-specific detection capabilities while managing resources efficiently through targeted allocation rather than universal sharing.
