Method for transmitting and receiving positioning reference signal in wireless communication system and device therefor
First Claim
1. A method of receiving a positioning reference signal by a User Equipment (UE), the method comprising:
- monitoring a positioning reference signal monitoring section;
receiving a positioning reference signal in one or more successive subframes included in the positioning reference signal monitoring section; and
transmitting information for measuring a location based on reception time information of the positioning reference signal to a Base Station (BS),wherein a resource element allocation pattern of the positioning reference signal is determined using a random number,wherein the resource element allocation pattern is selected from among six different resource element allocation patterns which have integer offset values 0 to 5, respectively, by randomly selecting one of the integer offset values.

Abstract
The present invention relates to a method for transmitting and receiving a positioning reference signal (PRS) in a wireless communication system. More specifically, the present invention relates to a detailed method and device for setting a transmission pattern for the PRS. Provided in one embodiment is a method by which a terminal receives the PRS, and a terminal device, the method comprising the steps of: monitoring the PRS in one PRS monitoring section; receiving the PRS in one or more consecutive subframes included in the one PRS monitoring section; and transmitting, to a base station, information for a position measurement by using reception time information of the PRS, wherein a resource element allocation pattern of the PRS is determined by a random number.
