1. A method for performing, by a user equipment (UE), reference signal time different (RSTD) measurement, comprising:

  • receiving, by the UE, a positioning reference signal (PRS) of a neighbor cell and a PRS of a reference cell; and

    measuring, by the UE, a RSTD with a RSTD measurement accuracy based on the PRSs of the neighbor and reference cells,wherein the RSTD is a relative timing difference between the neighbor cell and the reference cell, andwherein the RSTD measurement accuracy is determined based on a minimum PRS bandwidth which is minimum of a bandwidth of a serving cell, a bandwidth for the PRS of the neighbor cell and a bandwidth for a PRS of the reference cell.
