Synchronisation Signaling Spanning Multiple Allocation Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-frequency wireless communication systems face challenges in synchronisation signaling, particularly with the use of beamforming and millimeter wave frequencies, where existing methods struggle to ensure reliable and efficient synchronisation due to the need for precise timing and power management across short timescales.
Innovation Solution
The method involves transmitting synchronisation signaling across multiple allocation units within a synchronisation time interval, using primary synchronisation signaling that spans two or more allocation units, allowing for improved power distribution and reception, especially in high-frequency scenarios, by employing diverse signaling sequences and cyclic extensions to cover larger bandwidths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If synchronisation signaling is transmitted using traditional single-allocation unit methods, then the signaling structure is simple, but the reliability of synchronisation is insufficient in high-frequency environments with limited instantaneous power
Solution Approach 1:
The synchronisation signaling is divided into multiple allocation units, where the primary synchronisation signaling spans two or more allocation units within a synchronisation time interval. This segmentation allows the signaling energy to be distributed across multiple time resources, improving reliability in high-frequency environments with limited instantaneous power while maintaining a structured and manageable signaling framework
Solution Approach 2:
The synchronisation signaling is transmitted periodically across multiple allocation units in a systematic manner. The primary synchronisation signaling repeats across different allocation units within the synchronisation time interval, creating a periodic structure that enhances detection reliability without requiring complex non-periodic signaling designs
2Power
If synchronisation signaling spans multiple allocation units, then power distribution is improved for better reception, but the time resources required increase
Solution Approach 1:
By segmenting the synchronisation signaling across multiple allocation units, the total power requirement is distributed over time rather than concentrated in a single allocation unit. This allows for lower instantaneous power requirements while maintaining adequate total energy for reliable detection, effectively trading time extension for power reduction
Solution Approach 2:
The signaling approach changes the temporal distribution parameters of the synchronisation signal, spreading it across multiple allocation units with specific spacing and timing relationships. This parameter change optimizes the balance between instantaneous power requirements and total time interval, adapting to the constraints of high-frequency wireless communication systems
