7. A UE performing positioning, the UE comprising:
a controller identifying configuration information for a transmission bandwidth of a positioning reference signal (PRS) configured per cell;
a receiver receiving (i) configuration information for the positioning reference signal and (ii) the positioning reference signal corresponding to each cell based on the configuration information for the transmission bandwidth and the configuration information for the positioning reference signal; and
a transmitter configured to transmit a reference signal time difference (RSTD) index corresponding to an interval of a RSTD of the positioning reference signal received per cell based on a reporting table, to a base station,
wherein the reporting table is one corresponding to a reporting resolution given to the UE among per-resolution reporting tables which are defined to differ from each other, and
wherein the configuration information for the positioning reference signal comprises frequency domain allocation information including a number of resource elements set to one OFDM symbol per resource block through which the positioning reference signal is transmitted within a slot and time domain allocation information including location of a start symbol of the positioning reference signal within the slot.
