Abstract: Disclosed are a method for transmitting and receiving an uplink demodulation reference signal (DMRS) in a wireless communication system, and an apparatus therefore. Particularly, a method by which a terminal transmits a DMRS in a wireless communication system comprises the steps of: receiving, from a base station, downlink control information (DCI) for physical uplink shared channel (PUSCH) scheduling; generating a DMRS sequence for the PUSCH; and mapping the DMRS sequence to a physical resource, wherein the DMRS sequence can be mapped with the spacing of a predetermined resource element (RE) within the symbol to which the DMRS sequence is mapped.

Abstract: The present specification provides a method for handling a collision between a demodulation reference signal (DMRS) and a channel state information-reference signal (CSI-RS) in a wireless communication system. Specifically, the method performed by a terminal comprises the steps of: receiving a DMRS from a base station; receiving a CSI-RS from the base station; and when a collision between the DMRS and the CSI-RS occurs on at least one resource element (RE), puncturing a resource associated with the DMRS, or a resource associated with the CSI-RS on the basis of time domain behavior of the CSI-RS.
