Abstract: In some implementations, a location server may, in a positioning session between the location server and a user equipment (UE): receive, from the UE, a report message comprising reference signal time difference (RSTD) measurement information of an RSTD measurement, performed by the UE, of radio frequency (RF) signals, wherein: at least one RF signal of the RF signals is transmitted by an NTN Next Generation Radio Access Network (NG-RAN) node, and the RSTD measurement information comprises an offset to compensate for a delay in the at least one RF signal. The location server may determine a position of the UE based at least in part on the RSTD measurement information.

Abstract: Non-terrestrial networks (NTNs) may establish uplink (UL) and downlink (DL) radio frame timing structures to efficiently account for propagation delay and propagation delay variation associated with communications in the NTN. NTNs may manage (synchronize) radio frame timing structures of base stations (e.g., satellites) and user equipment (UEs) in the NTN. Further, UEs may determine timing advance (TA) values to be applied to UL transmissions based on their respective scheduling offset (e.g., offset in UL and DL radio frame timing structures), as well as based on propagation delay or round trip time (RTT). As such, served UEs may determine UL timing such that UL transmissions from the UEs to a satellite arrives at the satellite in a time synchronized manner. In other cases, a satellite may determine UL timing, based on reception timing, such that various UEs in the NTN may implement uniform UL and DL radio frame timing structures.
