Abstract

A method for measuring a reference signal for location determination in a wireless communication system, according to an embodiment of the present invention, is performed by means of a terminal. The method comprises the steps of: receiving the auxiliary data related to neighbor cells and a reference cell for location determination; by means of the auxiliary data, receiving a positioning referencesignal (PRS) or a cell-specific reference signal (CRS) of the reference cell or the neighbor cells and calculating a reference signal time difference (RSTD) measurement value; and reporting the measurement value to a location server, wherein the auxiliary data can comprise information about the number of CRS antenna ports of the reference cell and neighbor cells, CRS cyclic prefix (CP) length information, or configuration information about multicast broadcast single frequency network (MBSFN) subframes.

Description

technical field [0001] The present invention relates to a wireless communication system, and more particularly, to a method for measuring a reference signal for determining a position in a wireless communication system or a method for determining a position and an apparatus thereof. Background technique [0002] Recently, various devices requiring machine-to-machine (M2M) communication and high data transfer rates, such as smart phones or tablet personal computers (PCs), have emerged and are widely used. This rapidly increases the amount of data that needs to be processed in the cellular network. In order to meet such rapidly increasing data throughput, recently, carrier aggregation (CA) technology that effectively uses more frequency bands, cognitive radio technology, multiple antenna (MIMO) technology for increasing data capacity in limited frequencies, multiple Base station cooperation technology and the like have received attention. Furthermore, the communication envir...
