Abstract: Provided are a method for a terminal for carrying out uplink communication in a wireless communication system, and an apparatus using the method. The method receives an uplink communication-related parameter independently configured for each analog beam, and carries out the uplink communication on the basis of the parameter. If the uplink communication is carried out using a particular analog beam, then an uplink communication-related parameter configured on the particular analog beam is applied to the uplink communication.

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.
