Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the synchronization signal block from the neighbor cell is decoded to obtain time information, then the time information acquisition is accurate, but the decoding complexity increases
Solution Approach 1:
The patent extracts only the necessary time information from the reference signal sequence without performing complete synchronization signal block decoding. By using the reference signal sequence alone to determine time information through correlation operations, the system obtains the required timing data while avoiding the complex decoding process of the entire synchronization signal block.
Solution Approach 2:
The patent performs partial action by using only the reference signal sequence portion of the synchronization signal block for time information acquisition. Instead of decoding the entire synchronization signal block which includes multiple components (synchronization signals, broadcast channel, etc.), the method selectively uses only the reference signal sequence for correlation-based time determination, reducing unnecessary processing.
2Productivity
If the reference signal sequence is used to obtain time information without decoding the synchronization signal block, then the decoding complexity is reduced, but the traditional methods require complete decoding which increases processing overhead
Solution Approach 1:
The patent extracts only the necessary time information from the reference signal sequence without performing complete synchronization signal block decoding. By using the reference signal sequence alone to determine time information through correlation operations, the system obtains the required timing data while avoiding the complex decoding process of the entire synchronization signal block.
Solution Approach 2:
The patent uses the reference signal sequence as a simplified copy or representation of the full synchronization signal block for the specific purpose of time information acquisition. Instead of processing the complete original structure, the method works with this extracted sequence that contains sufficient information for timing determination, reducing computational complexity.

AI summary
Disclosed is a method for a terminal to receive a reference signal in a wireless communication system. In particular, the method comprises: receiving first information related to a reference signal configuration from a serving cell; receiving the reference signal from a neighbor cell on the basis of the first information; and obtaining second information on the timing of the reference signal on the basis of the sequence of the reference signal, wherein the reference signal is of a different type from a SS/PBCH block.
