Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless network technologies face challenges in efficiently controlling repeater beam switching in network-controlled repeaters, leading to potential impacts on user equipment due to increased overhead and latency.
Innovation Solution
A method is introduced where a network node configures the periodic behavior of a spatial filter of a repeater node by indicating a beam to use and its associated beam time-domain state, thereby facilitating accurate and low-latency control of repeater beams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If dynamic beam switching control is implemented in network-controlled repeaters, then beam alignment accuracy is improved, but signaling overhead and latency increase
Solution Approach 1:
The patent applies periodic action by configuring the repeater to switch beams periodically rather than dynamically on-demand. The network node indicates a beam time-domain state that includes periodicity information, causing the repeater to switch between beams at predetermined intervals. This periodic approach reduces the frequency of beam switching operations, thereby reducing signaling overhead and latency while maintaining adequate beam alignment accuracy for the intended communication scenarios.
2Adaptability or versatility
If frequent beam switching is performed to adapt to changing network conditions, then network adaptability is improved, but control latency increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring the beam time-domain state including periodicity information before actual beam switching occurs. The network node indicates the periodic behavior in advance, allowing the repeater to prepare and execute beam switching at predetermined intervals without waiting for real-time triggers. This reduces control latency while maintaining network adaptability through periodic adaptation to changing conditions.
3Reliability
If continuous beam monitoring and adjustment is performed, then communication reliability is improved, but energy consumption increases
Solution Approach 1:
The patent applies periodic action by configuring the repeater to monitor and adjust beams at predetermined intervals rather than continuously. The beam time-domain state includes periodicity information that guides the repeater to perform reliability-checking operations at specific time points. This periodic monitoring maintains communication reliability by detecting and correcting beam misalignment at regular intervals while significantly reducing energy consumption compared to continuous monitoring and adjustment operations.
