In this paper, the architecture and mechanism of 5G New Radio indoor positioning schemes such as downlink time difference of arrival (DL-TDOA), uplink (UL) TDOA, multiple-cell round trip time (Multi-RTT), DL angle of departure, UL angle of arrival (AOA), and enhanced cell-ID, are comprehensively described. In addition, their performances are investigated under different channel bandwidths and conditions, and antenna configurations. Numerical results show the time-based schemes provide more benefit by wider bandwidth, while the angle-based schemes give gains by more antenna elements. Note that the Multi-RTT achieves the best accuracy with line-of-sight (LOS) conditions, while the UL-AOA does with non-LOS. © 2025 The Author(s).
