Abstract (en)

[origin: WO2020069314A1] Techniques discussed herein can facilitate inter-RAT (Radio Access Technology) E (Enhanced)-UTRA (UMTS (Universal Telecommunications Systems) Terrestrial Radio Access) RSTD (Reference Signal Time Difference) measurement. One example embodiment comprises a UE (User Equipment) configured to: process LPP (LTE (Long Term Evolution) Positioning Protocol) signaling that configures PRS(s) (Positioning Reference Signal(s)) of a target cell; process additional signaling that indicates a timing offset of the target cell relative to a serving cell, wherein the target cell employs a different RAT (Radio Access Technology) than the serving cell; generate a request for a measurement gap from the serving cell based on the timing offset; process configuration signaling that configures the measurement gap; and perform a RSTD (Reference Signal Time Difference) measurement of the target cell during the measurement gap.
