Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus at a UE in NTN are provided. The UE may be configured to receive one or more FPC commands from an NTN. The UE may be further configured to transmit, in response to receiving the one or more FPC commands, an uplink transmission with a frequency change having a total FPC adjustment calculated based on (a) a current UE location update and a current UE velocity update, wherein the total FPC adjustment satisfies one or more threshold requirements, or (b) an intermediary UE location update between the current UE location update and a previous UE location update and an intermediary UE velocity update between the current UE velocity update and a previous UE velocity update.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network entity may cause a first transmission reception point (TRP) to transmit a first communication using a first time value derived from a first transmission configuration indicator (TCI) state including a set of first quasi co-location (QCL) parameters of the first TRP. The network entity may cause a second TRP to transmit a second communication using a timing pre-compensation value relative to the first time value. Numerous other aspects are described.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may transmit, and a user equipment (UE) may receive, signaling indicating one or more common timing offset parameters that are based at least in part on one or more delays between a satellite and a reference point in a non-terrestrial network (NTN). The UE may determine a transmit time for an uplink signal based at least in part on the one or more common timing offset parameters and a starting time associated with an uplink slot in which the uplink signal is to arrive at the reference point. The UE may transmit the uplink signal at the transmit time. Numerous other aspects are described.
