This study analyzes the performance of positioning techniques based on configuration changes of 5G New Radio (NR) signals. In 5G networks, a terminal's position is determined from the Time of Arrival (TOA) of Positioning Reference Signals (PRS) transmitted by base stations. We propose an algorithm that improves TOA accuracy under low sampling-rate constraints and implement 5G PRS for positioning in a software-defined modem. We also examine how flexible time-frequency resource allocation of PRS affects TOA estimation accuracy and discuss optimal PRS configurations for a given signal environment. With the proposed configuration, the terminal can achieve sub-sample TOA accuracy, reaching approximately 0.3 samples.
