Synchronisation Signaling Allocation Units for Wireless Networks
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 transmission and identification of cells and transmitters due to short timescales and power constraints.
Innovation Solution
The proposed method involves transmitting synchronisation signaling in a synchronisation time interval covering at least 10 allocation units, with optimised allocation of primary and secondary synchronisation signaling, broadcast signaling, and using shifting techniques to enhance transmission diversity and power efficiency, particularly suited for high-frequency scenarios like 6G networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If synchronisation signaling is transmitted in short time intervals to meet high-frequency timing requirements, then timing precision is improved, but transmission power becomes insufficient
Solution Approach 1:
The synchronisation time interval is divided into multiple allocation units (at least 10), where each allocation unit carries a portion of the synchronisation signaling. This segmentation allows the total transmission power to be distributed across multiple shorter transmissions within the time interval, maintaining timing precision while ensuring sufficient cumulative power for reliable detection
Solution Approach 2:
Synchronisation signaling is transmitted periodically within the synchronisation time interval across multiple allocation units. This periodic transmission ensures that the signaling is repeated frequently enough to meet high-frequency timing requirements while accumulating sufficient transmission power through multiple opportunities
2Measurement precision
If beamforming with small beams is used to improve directional communication, then communication precision is improved, but synchronisation identification becomes more difficult
Solution Approach 1:
The synchronisation signaling is designed to serve multiple functions simultaneously: it provides timing synchronization, cell identification, and beam identification. By embedding beam identification information within the synchronisation signaling transmitted across multiple allocation units, the system maintains small beam precision while enabling receivers to identify both the cell and the specific beam being used
Solution Approach 2:
The solution adds a temporal dimension to the beamforming approach by distributing synchronisation signaling across multiple allocation units in time. This temporal spreading complements the spatial focusing of small beams, allowing receivers to accumulate energy from multiple time instances while maintaining directional precision
