The 60GHz unlicensed frequency band can achieve higher positioning signal measurement accuracy due to its wireless propagation characteristics of short wavelength and wide band; Therefore, 5G NR-U equipment for high-precision positioning based on the 60GHz frequency band has attracted much attention; However, 5G network is a multi-network heterogeneous coexistence system, which has many devices with different radio access technologies (RAT); Thus there are many potential hidden nodes in 60GHz band, even if 5G NR-U devices use listen before talk (LBT) to access 60GHz radio channel, they can not avoid hidden nodes effectively, which sometimes interfere with positioning signal transmission and affect positioning performance seriously; To solve the above hidden node issue, this paper proposes to configure different spatial relationships for multiple positioning signal resources in the positioning signal resource set, and the receiver dynamically adjusts their spatial relationships in real time according to the measurement results, so as to avoid potential hidden nodes as much as possible; Simulation results show that the proposed method can improve the measurement accuracy of the positioning signal by about 27% and significantly reduce the positioning error.
