Abstract: A method for transmitting and receiving a Reference Signal in a wireless communication system performed by a UE is disclosed. According to the present invention, a UE receives, from a base station, Downlink Control Information and receives a Demodulation Reference Signal (DMRS) through a plurality of antenna ports based on the Downlink Control Information and downlink data.The UE demodulates the downlink data based on the DMRS, and the downlink data is received in a same symbol as the DMRS or in different symbols with each other based on a number of symbols related to the downlink data.

Abstract: The present invention discloses a method for a terminal to receive a synchronization signal in a wireless communication system. Particularly, the method includes the steps of receiving a synchronization block including a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcasting channel (PBCH) and receiving a DMRS (demodulation reference signal) via resource region in which the PBCH is received. In this case, an index of the synchronization block can be determined in consideration of a sequence of the DMRS.

Abstract: The present specification provides a method for transmitting and receiving an uplink channel in a wireless communication system, and a device therefor. Particularly, a method for transmitting an uplink channel by a terminal in a wireless communication system can comprise the steps of: receiving, from a base station, information indicating a first timing offset for channel state information (CSI) reporting and/or a second timing offset for transmitting uplink data; and transmitting an uplink data channel to the base station in a resource region configured in accordance with a specific timing offset value. The specific timing offset value can be set by applying the first timing offset and/or the second timing offset in accordance with the type of information allocated to the uplink data channel.

Abstract: This specification provides a method of transmitting an uplink signal based on a codebook in a wireless communication system. More specifically, the method performed by a UE includes receiving, from a base station, downlink control information (DCI) including a first transmit precoding matrix indicator (TPMI), determining a codebook subset related to the transmission of the uplink signal based on the first TPMI, and transmitting, to the base station, the uplink signal based on the determined codebook subset. Accordingly, there is an advantage in that flexibility in the transmission antenna design of a UE can be increased because the degree of freedom of antenna port selection is increased.

Abstract: The present invention relates to a method and an apparatus for receiving a reference signal by a terminal in a wireless communication system. According to the present invention, from a base station, a terminal receives configuration information of a channel state information (CSI)-RS resource for transmission of a CSI-RS, and receives the CSI-RS on the basis of the configuration information. Further, provided may be a method and an apparatus, in which a terminal configures a beam on the basis of the CSI-RS, wherein the configuration information includes at least one of a first indicator indicating the number of times the CSI-RS is repeatedly transmitted, a first offset value of a first subcarrier to which the CSI-RS resource is mapped, and information indicating the maximum number of times the terminal can perform beam sweeping, and the CSI-RS resource is mapped to subcarriers at a predetermined interval on a frequency axis, and the CSI-RS can be repeatedly transmitted within a specific time interval according to the first indicator.

Abstract: Disclosed herein is a method for reporting channel state information (CSI) of a terminal in a wireless communication system. The method includes: measuring a CSI-RS (reference signal) transmitted from a base station through multiple panels; and reporting CSI generated based on the CSI-RS measurement to the base station, wherein, when the terminal reports a WB (Wideband) panel corrector and SB (Subband) panel corrector for the multiple panels as the CSI, the WB panel corrector and the SB panel corrector are reported with different bit widths.
