Synchronization Signal Mapping for 5G NR Detection Burden
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the 5G NR wireless communication system, user equipment faces increased detection burden due to varying time/frequency positions of synchronization signals, which are essential for initial network entry, especially when different resource structures are used.
Innovation Solution
The method involves mapping synchronization signals to symbols with different resource structures, ensuring that the time/frequency positions coincide regardless of the structure, with specific configurations for subcarrier spacing, symbol duration, and multiplexing schemes to optimize detection burden.

Engineering Contradiction Analysis
1Adaptability or versatility
If synchronization signals are transmitted with varying time/frequency positions to support different resource structures, then system adaptability is improved, but user equipment detection burden increases
Solution Approach 1:
The patent applies local quality by making different parts of the synchronization signal transmission have different properties. Specifically, PSS and SSS are transmitted with different resource structure configurations (different subcarrier spacings, different symbol positions), allowing each signal type to be optimized for its specific detection requirements while maintaining overall system adaptability
Solution Approach 2:
The patent achieves equipotentiality by ensuring that despite using different resource structures for PSS and SSS, both signals are transmitted at the same time position and frequency position. This creates equal detection conditions for user equipment, allowing simultaneous detection of both signals without increased complexity
2Adaptability or versatility
If different resource structures are used for synchronization signals, then system versatility is improved, but signal detection precision deteriorates
Solution Approach 1:
Different resource structures (subcarrier spacings, symbol durations) are applied locally to PSS and SSS based on their specific detection requirements, allowing each signal to be optimized while maintaining overall detection precision
Solution Approach 2:
By transmitting PSS and SSS at identical time and frequency positions despite using different resource structures, the patent ensures that user equipment can detect both signals with equal precision without needing to adjust detection parameters

AI summary
A method for transmitting a signal in a wireless communication system is disclosed. To this end, any one of first category signals comprising a synchronization signal is mapped to a symbol having any one structure of a first resource structure and a second resource structure having mutually different symbol structures, and the mapped signal is transmitted, wherein any one of a time domain location and a frequency domain location in case the first category signal is mapped to a symbol having the first resource structure coincides with any one of a time domain location and a frequency domain location in case the first category signal is mapped to a symbol having the second resource structure.
