Abstract: In an aspect of the disclosure, a serving base station receives, from a UE, a measurement of a DL-RSTD with respect to a first TRP and a second TRP. The serving base station sends the DL-RSTD to a location management function, wherein the location management function further receives a first RTOA of an SRS arriving at the first TRP and a second RTOA of the SRS arriving at the second TRP. The serving base station receives, from the location management function, a relative time difference calculated based on the DL-RSTD, the first RTOA, and the second RTOA. The relative time difference indicates a synchronization error between the first TRP and the second TRP.
