Classification: CPC G  H | IPC H

Claim 7:
8. A location server configured for determining a location for a user equipment (UE) using round-trip time (RTT) for signals between the UE and a plurality of gNBs in a wireless network, comprising:
a network interface configured to communicate with other entities in the wireless network;
at least one memory; and
at least one processor coupled to the network interface and the at least one memory and configured to:
receive, via the network interface, from the UE a first report for downlink (DL) positioning reference signals (PRS) measurements performed by the UE for DL PRS transmitted by each gNB in the plurality of gNBs;
receive, via the network interface, from each gNB a gNB report for UE sounding reference signals (SRS) measurements performed by each gNB for UE SRS transmitted by the UE;
determine RTTs between the UE and each gNB using the DL PRS measurements performed by the UE and the UE SRS measurements performed by each gNB; and
determine a position of the UE based on at least the RTTs between the UE and each gNB.
