1. A method for signal communication of a wireless communication system, the method comprising:
- allocating N consecutive downlink subframes for a positioning reference signal (PRS) to each period of a plurality of periods for at least one base station, the PRS being allocated as large as a PRS bandwidth of a total bandwidth;
by the at least one base station, transmitting the PRS or muting the PRS to a terminal in the N consecutive downlink subframes of at least one period of the plurality of periods;
by the terminal, receiving at least one of the transmitted PRS or the muted PRS from the at least one base station in the N consecutive downlink subframes of the at least one period of the plurality of periods; and
by the terminal, calculating at least one difference of arrival time of the transmitted PRS or the muted PRS from the at least one base stationwherein the N, the PRS bandwidth, and the period of the at least one base station are delivered to the terminal from the at least one base station; and
wherein transmitting the PRS or muting the PRS comprises transmitting all PRS or muting all PRS in the N consecutive downlink subframes of the at least one period of the plurality of periods.

Abstract
Disclosed are apparatuses and methods for signal transmission/reception between a user equipment (UE) and a base station (BS) or cell in a wireless communication system in which a position of a US may be determined by identifying according to a positioning reference signal (PRS) pattern. By a method of transmitting PRSs using a more effective and efficient muting method, it is possible to reduce interference between multiple base stations that simultaneously transmit a same PRS pattern.
