Unified Synchronization Signal Configuration for Wireless Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face interference and complexity in synchronizing signals across different communication modes, particularly due to varying subcarrier spacings, which hinders efficient signal detection and processing.
Innovation Solution
A unified synchronization signal configuration is introduced, featuring a split configuration with predetermined gaps to accommodate different communication modes, allowing the same synchronization signal design to be used across multiple modes, and including PSS, SSS, and PBCH signals, with boundary information embedded in synchronization signals to facilitate detection and processing.

Engineering Contradiction Analysis
1Measurement precision
If different synchronization signal designs are used for different communication modes, then signal detection accuracy is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by designing a single synchronization signal configuration that can be used across multiple communication modes (e.g., different subcarrier spacings). The base station transmits synchronization signals with a unified design that works for both 15 kHz and 30 kHz subcarrier spacings, eliminating the need for separate signal designs for each mode. This reduces device complexity while maintaining signal detection accuracy through the universal design.
2Productivity
If communication block boundary indication is embedded in synchronization signals, then signal processing efficiency is improved, but measurement precision requirements increase
Solution Approach 1:
The patent applies preliminary action by embedding communication block boundary indication information in advance within the synchronization signals. The base station includes boundary information in the synchronization signal transmission before the actual data transmission begins, allowing the user equipment to pre-determine the communication block boundaries. This preliminary provision of boundary information improves signal processing efficiency during data reception without requiring high-precision measurements during the actual data transmission phase.
