Abstract

According to an embodiment of the present specification, a method for transmitting, by a base station, a signal for eliminating phase noise by a terminal in an mmWave communication system may be provided. A method for transmitting a signal for eliminating phase noise may comprise the steps of: generating a PTRS; allocating the PTRS to one or more resource blocks included in a scheduled bandwidth;and transmitting the allocated PTRS, wherein an interval between the one or more resource blocks, to which the PTRs are allocated, is determined on the basis of the scheduled bandwidth.

Description

technical field [0001] The present disclosure relates to a wireless communication system, and more particularly, to a method and apparatus for allocating a phase tracking reference signal (PTRS) for phase noise cancellation to resource blocks in the system. Background technique [0002] UHF wireless communication systems based on mmWave are configured to operate at a center frequency of several GHz to tens of GHz. Due to the nature of the center frequency, significant path loss can occur in radio shadow areas. Since synchronization signals must be stably transmitted to all terminals belonging to the coverage of the base station, it is necessary to design and transmit synchronization in mmWave communication systems in consideration of a potential deep-null phenomenon that can occur due to the characteristics of the ultra-high frequency band. Signal. Contents of the invention [0003] technical problem [0004] The present disclosure aims to solve the above-mentioned prob...
