Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If PRS information is transmitted using existing wireless communication methods, then positioning functionality is provided, but positioning accuracy and reliability are insufficient for 6G requirements
Solution Approach 1:
The patent applies parameter changes by modifying PRS configuration parameters including comb offset values, comb size, and starting symbol positions. These parameter variations enable multiple PRS resources to be configured with different time-frequency characteristics, improving both positioning accuracy and reliability by providing diverse measurement opportunities under varying channel conditions
Solution Approach 2:
The patent segments positioning reference signals into multiple PRS resources with distinct configurations. Each PRS resource contains specific combinations of comb offset, comb size, and symbol positions, allowing the system to divide the positioning function into multiple independent measurement components that can be evaluated separately for accuracy and reliability
2Measurement precision
If multiple PRS resources are configured for positioning, then positioning accuracy improves, but device complexity increases
Solution Approach 1:
The patent implements universality by designing a unified PRS resource configuration framework that handles multiple PRS resources through standardized parameters. The same configuration mechanisms (comb offset, comb size, starting symbol) apply across all PRS resources, allowing the system to manage multiple resources without proportionally increasing device complexity through standardized processing procedures

AI summary
Proposed are a method by which a first device performs wireless communication and an apparatus supporting same. For example, the first device may acquire information related to a PRS, which comprises at least one of information regarding a PRS comb offset, information regarding a PRS comb size, information regarding a PRS start symbol, and information regarding the number of PRS symbols. For example, the first device may receive a first PRS. For example, the first device may receive a second PRS. For example, the first device may transmit measurement information comprising: (i) information regarding an RSTD regarding the first PRS and the second PRS; and (ii) identification information for identifying a PRS resource used for the RSTD.
