Abstract
The present invention relates to a method for determining position of a user equipment in a wireless mobile communication system. The method comprises receiving a plurality of subframes including reference signals for positioning of the user equipment from a plurality of base stations periodically with a predetermined period of time; and determining position of the user equipment using reference signal time difference (RSTD) between the reference signals for positioning of the user equipment included in the received plurality of subframes, wherein a pattern of the reference signals for positioning of the user equipment is generated by repeating a diagonal mother matrix with dimension of 6×6, the pattern of the reference signals are mapped to orthogonal frequency division multiplexing (OFDM) symbols of the subframe, and the reference signals for positioning of the user equipment in a OFDM symbol in which common reference signal (CRS) is transmitted are punctured.
