    Abstract: Disclosed are a method for transmitting and receiving a sounding reference signal (SRS) in a wireless communication system, and an apparatus therefor. Specifically, a method for a terminal to transmit an SRS in a wireless communication system comprises: a step of receiving, from a base station, SRS configuration information, wherein the SRS configuration information includes SRS bandwidth configuration information related to an SRS hopping pattern; and a step of determining, on the basis of the SRS bandwidth configuration information, a first parameter indicating the entire bandwidth allocated to the SRS, a second parameter indicating a bandwidth for hopping units of the SRS, and a third parameter indicating the number of hopping units of the SRS, and transmitting the SRS to the base station by applying the SRS hopping pattern configured on the basis of the first parameter, the second parameter, and the third parameter, wherein the value of the third parameter may be configured in association with the number of symbols constituting the SRS hopping pattern.

    Abstract: The present invention relates to a method for receiving a downlink signal in a wireless communication system. The method, according to one embodiment of the present invention, is performed by a terminal and may comprise the steps of: receiving control information indicating an aperiodic channel state information-reference signal (CSI-RS) resource masked with an identifier associated with an aperiodic CSI-RS; if the control information does not indicate an aperiodic CSI-RS resource for each terminal in a cell, determining that the aperiodic CSI-RS resource indicated by the control information is a resource element (RE) puncturing pattern for a downlink data channel or an improved downlink control channel; and decoding the downlink data channel or the improved downlink control channel by using the RE puncturing pattern.

    Abstract: The present specification provides a method for measuring and reporting channel state information (CSI) in a wireless communication system and a device for same. More particularly, in a method for reporting channel state information in a wireless communication system, the method which is carried out by means of a base station can comprise the steps of: transmitting CSI report configuration information associated with a CSI report to a terminal, wherein the CSI report configuration information comprises information indicating a time offset for the CSI report; transmitting a channel state information reference signal (CSI-RS) to the terminal; transmitting control information, which is for triggering the CSI report, to the terminal; and receiving from the terminal the CSI report which is generated on the basis of the measurement with respect to the CSI-RS. Here, if the information indicating the time offset for the CSI report is configured in “0” value, the CSI-RS can be transmitted periodically or semi-continuously.
