Abstract: A method for a base station to transmit a signal allowing a terminal to remove phase noise in an mmWave communication system, according to an embodiment of the present specification, may be provided. Here, the method for transmitting a signal for removing phase noise comprises: a step of generating a phase tracking reference signal (PTRS) and a first RS; a step of assigning the PTRS and the first RS to a resource block; and a step of transmitting the assigned PTRS and first RS, wherein the step of assigning the PTRS and the first RS includes a step of changing a frequency location of the PTRS if the PTRS and the first RS collide in the resource block, wherein the changed PTRS frequency location may be changed to a frequency location, across frequencies on which a predetermined demodulation reference signal (DMRS) port, associated with the PTRS, in a DMRS port group is located, which is closest to the existing PTRS frequency location and avoids collision with the first RS.

Abstract: Provided are a method and an apparatus for detecting a random access channel (RACH) preamble on the basis of a plurality of zero-correlation zones (ZCZ) in a wireless communication system. A user equipment (UE) transmits a RACH preamble, generated using a combination of a plurality of sequences corresponding to a plurality of zero-correlation zones, to an evolved NodeB (eNB). The evolved NodeB (eNB) detects a plurality of peaks from the RACH preamble and transmits a random access response to the UE.
