REFERENCE SIGNAL TIME DIFFERENCE (RSTD) MEASUREMENTS FOR OBSERVED TIME DIFFERENCE OF ARRIVAL (OTDOA) POSITIONING

摘要

Technology for a UE configured to perform RSTD measurements for OTDOA positioning is disclosed. The UE can decode a MBSFN subframe configuration information for one or more cells in a plurality of cells. The UE can decode PRS configuration information for one or more cells in the plurality of cells. The UE can determine, for the one or more cells in the plurality of cells, an existence of a CRS for selected subframes of a plurality of subframes based on the MBSFN subframe configuration information. The UE can determine for the one or more cells in the plurality of cells, an existence of a PRS for selected subframes of the plurality of subframes based on the PRS configuration information. The UE can measure the RSTD for the one or more cells in the plurality of cells using the CRS and the PRS.
