摘要： Systems and techniques or transmitting and receiving a sounding reference signal (SRS) in a wireless communication system. In some implementations, a method for transmitting, by a terminal, an SRS in a wireless communication system includes: receiving configuration information for transmission of the SRS from a base station; and transmitting the SRS to the base station by using one or more SRS resources for transmission of the SRS, the configuration information including the one or more SRS resources and information relating to usage of the one or more SRS resources, wherein a guard period relating to the one or more SRS resources is configured, and when the transmissions of the guard period and a particular uplink channel configured for the terminal overlap each other, the priority between the guard period and the particular uplink channel is configured to be the same as that between the SRS and the particular uplink channel.

摘要： 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.

摘要： The present invention provides a method for transmitting or receiving a sounding reference signal in a wireless communication system and an apparatus therefor. Specifically, a method for transmitting a sounding reference signal (SRS) by a terminal in a wireless communication system may comprise the steps of: receiving, from a base station, configuration information for transmission of the SRS, wherein the configuration information includes one or more SRS resources for transmission of the SRS, a cyclic shift (CS) hopping pattern for the SRS, and CS relation information about whether CS hopping patterns of the SRS and a PUCCH are related; and transmitting the SRS to the base station, through at least one SRS resource among the one or more SRS resources, wherein a CS value applied to the SRS is configured on the basis of the CS hopping pattern for the SRS and the CS relation information.

摘要： According to one embodiment of the present invention, a method of decoding, by a user equipment, a downlink signal in a wireless communication system comprises the steps of: receiving a semi-persistent zero power-channel state information reference signal (SP ZP CSI-RS) resource configuration from a base station; and decoding a downlink signal according to the SP ZP CSI-RS resource configuration. The SP ZP CSI-RS resource configuration includes a plurality of SP ZP CSI-RS resources and information on whether or not each of a plurality of the SP ZP CSI-RS resources is used can be indicated or configured by the base station.
