METHOD AND APPARATUS FOR TRANSMITTING POSITIONING REFERENCE SIGNAL IN WIRELESS COMMUNICATION SYSTEM

摘要

Provided are a method and an apparatus for transmitting a positioning reference signal (PRS) in a wireless communication system. A terminal obtains positioning subframe configuration information to determine at least one positioning subframe among a plurality of downlink subframes in a wireless frame, obtains downlink subframe configuration information to determine the type of each downlink subframe in the wireless frame, receives PRSs in at least one positioning subframe from a plurality of cells, and reports measured time differences between the PRSs received from the plurality of the cells. The type of each downlink subframe of the wireless frame is classified into a 1st type subframe and a 2nd type subframe, and the type of at least one positioning subframe is either the 1st type subframe or the 2nd type subframe. In addition, the PRSs are mapped into at least one positioning subframe on the basis of a single PRS pattern.

1. A method for transmitting, by a base station, a positioning reference signal (PRS) in a wireless communication system, the method comprising:
configuring a plurality of subframes as positioning subframes, each of the plurality of configured subframes consisting of 7 orthogonal frequency division multiplexing (OFDM) symbols in one slot, wherein the plurality of subframes includes both a subframe that has a specific cyclic prefix (CP) length, hereinafter a normal subframe, and a multimedia broadcast multicast service single frequency network (MBSFN) subframe having a CP length that is the same as the normal subframe; transmitting a PRS to a user equipment in the positioning subframes.
