Abstract

The present invention relates to a wireless communication system in which a terminal transmits an uplink reference signal. A method for configuring a reference signal for a transmission point according to one embodiment of the present invention is characterized by: a reference signal information transmission step for transmitting, via RRC (Radio Resource Control) or PBCH (Physical Broadcasting Channel), domain configuration information about a domain which allocates an uplink reference signal via a portion of sub-carriers which are regularly spaced; and a resource allocation information transmission step for transmitting resource allocation information about a resource domain in which a particular terminal transmits an uplink signal.
