20 Claims

1. A user equipment (UE) for wireless communication, comprising:

at least one memory; and

at least one processor coupled with the at least one memory and configured to cause the UE to:

receive, from a location server of a non-terrestrial network (NTN), first control signaling indicating a first positioning reference signal (PRS) configuration comprising positioning assistance data and measurement reporting configuration, wherein the positioning assistance data comprises a PRS muting pattern that is based at least in part on a Doppler shift of PRSs;

receive second control signaling indicating a second PRS configuration based at least in part on the first control signaling, the second PRS configuration indicating adapted PRS information based at least in part on one or more of mobility, an interference level, or a propagation delay pattern;

receive third control signaling indicating a third PRS configuration based at least in part on the second control signaling, the third PRS configuration comprising a duration for reporting a measurement of the PRSs based at least in part on the adapted PRS information; and

transmit, to the location server of the NTN, a report indicating at least one of a timing drift associated with the Doppler shift of the PRSs, the measurement of the PRSs, or a location estimate based at least in part on the duration for the reporting.
