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: 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.

Abstract: A method and an apparatus for transmitting/receiving a downlink signal in a wireless communication system are provided. Carrier information about a second carrier that is different from a first carrier can be transmitted on the first carrier. Downlink data for UE can be transmitted on the second carrier based on the carrier information. The first carrier is a carrier having a synchronisation signal and a physical broadcast channel, and the second carrier can be a carrier without any synchronisation signals or physical broadcast channels. The first carrier can be operated on a single resource block in a guard frequency that is used in the wireless communication system.

Abstract: In the present invention, when a UE transmits a random access preamble, the UE maintains a power ramping counter used for determination of a transmission power equally to a value of previous transmission without incrementing the power ramping counter if a target synchronization signal block is changed differently from a previous random access preamble transmission.

Abstract: A method is provided for receiving a user equipment (UE) specific reference signal based-downlink data channel by a UE in a wireless communication system. The UE receives, from a network, a downlink control channel including either first scheduling information or second scheduling information, and receives the UE-specific reference signal based-downlink data channel from the network based on the downlink control channel. When the downlink control channel includes the first scheduling information, antenna ports of a certain reference signal which can be assumed to be quasi co-located with antenna ports of a UE-specific reference signal is configured by an indicator indicating one of two or more parameters configured by a higher layer. When the downlink control channel includes the second scheduling information, the antenna ports of a certain reference signal is configured by a parameter of a minimum index among the two or more parameters.

Abstract: In the present invention, a part of a first demodulation reference signal sequence generated on the basis of a basic subcarrier interval (hereinafter, a first subcarrier interval) is used for a second subcarrier interval which is K times the first subcarrier interval. Values selected one for every K from among values constituting the first demodulation reference signal sequence may be used as values constituting a second demodulation reference signal sequence for the second subcarrier interval.
