Abstract: The present invention provides a method for transmitting a random access channel (RACH). Particularly, the method includes receiving PRACH configuration information including information about a slot (RACH slot) available for transmission of the RACH and information indicating a subcarrier spacing for a PRACH, and transmitting a RACH preamble in the RACH slot on the basis of the PRACH configuration information and the subcarrier spacing, wherein the length of the RACH slot depends on the subcarrier spacing.

Abstract: First downlink scheduling information for a first subframe and second downlink scheduling information for a second subframe can be transmitted and received in the first subframe. A first type downlink data channel can be transmitted and received in the first subframe according to the first downlink scheduling information, and a second type downlink data channel can be transmitted and received in the second subframe according to the second downlink scheduling information. Each of the first subframe and the second subframe may comprise a downlink control region and a data region in a time domain. The first downlink scheduling information and the second downlink scheduling information can be transmitted and received in the downlink control region of the first subframe. The first type downlink data channel is transmitted and received in the data area of the first subframe, and the second type downlink data channel can be transmitted and received in the downlink control region of the second subframe. The data area of the first subframe and the downlink control area of the second subframe can be continuous with each other.

Abstract: The present invention discloses a method for a user equipment to receive a PDCCH (Physical Downlink Control Channel) for RMSI (Remaining Minimum System Information). The method comprises: receiving an SS/PBCH block containing an SS (Synchronization Signal) and a PBCH (Physical Broadcasting Channel); obtaining information related to a CORESET (Control resource set) for the PDCCH; and receiving the PDCCH within the CORESET based on the information. The information includes an offset between a frequency position of the SS/PBCH block related to the COPRESET and a frequency position of the CORESET. Values of the offset are defined based on subcarrier spacing of the SS/PBCH block and a minimum channel bandwidth.

Abstract: According to an embodiment of the present specification, provided is a method for transmitting a signal that allows a user equipment to cancel phase noise by a base station in an mmWave communication system. In this case, the method may include: generating a PTRS for estimating phase noise of a downlink signal; transmitting PTRS power boosting level information for the PTRS to the user equipment via downlink signaling; and transmitting the PTRS via downlink signaling based on the PTRS power boosting level information. In this case, the PTRS power boosting level information may be determined based on at least one of MCS level and PRB size.

Abstract: A user equipment (UE) receives UE group information indicating a first UE group to which the UE belongs, and transmits uplink (UL) data and a demodulation reference signal (DM-RS), which is for demodulating the UL data, on the basis of the UE group information. The DM-RS is transmitted by means of a first uplink demodulation reference signal (UL DM-RS) resource, which corresponds to the first UE group to which the UE belongs, among a plurality of UL DM-RS resources respectively corresponding to one or more UE groups.
