    Abstract: A method for reporting channel state information (CSI) in a wireless communication system is disclosed. More specifically, the method performed by a user equipment (UE) includes receiving, from a base station, configuration information related to the channel state information, wherein the configuration information includes a number of a plurality of subbands allocated to the UE; measuring parameter values related to a channel state of one or more subbands of the plurality of subbands based on the configuration information; and reporting, to the base station, channel state information of the one or more subbands including the measured parameter values, wherein a number of the one or more subbands is determined based on a value of a rank indicator (RI).

    Abstract: 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.

    Abstract: The present disclosure provides a method for transmitting and receiving a sounding reference signal (SRS) in a wireless communication system and a device therefor. Specifically, a method for transmitting, by a terminal, an SRS in a wireless communication system may comprise the steps of: 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 the 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.

    Abstract: A method for transmitting an SRS by a terminal may comprise the steps of: receiving, from a base station, one of an SRS resource indicator (SRI), a CSI-RS resource indicator (CRI), a synchronization signal block (SSB) identifier, and an uplink transmission configuration indicator (TCI); on the basis of whether the received indicator/identifier includes an indication that the corresponding indicator/identifier is commonly used for an SRS resource group or an indication that the corresponding indicator/identifier is used for a first SRS resource of the SRS resource group, determining whether to use the same transmission beam or use different transmission beams to transmit an SRS in the SRS resource group; on the basis of the determination, determining a transmission beam for the terminal, indicated by the received indicator/identifier; and transmitting the SRS in the first SRS resource on the basis of the transmission beam for the terminal, wherein the SRS resource group includes the first SRS resource and a second SRS resource. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.
