    Abstract: A method and an apparatus for transmitting and receiving channel state information (CSI) in a wireless communication system are disclosed. A method of performing downlink reception by a user equipment (UE) in a wireless communication system according to an embodiment of the present disclosure may comprise: receiving, from a base station, configuration information for two or more control resource set (CORESET) groups, each of the two or more CORESET groups including at least one CORESET; receiving, from the base station, information indicating two or more transmission configuration indicator (TCI) states; and based on the two or more TCI states, updating TCI state information for the two or more CORESET groups. Here, at least one of the two or more CORESET groups may include a specific CORESET associated with a plurality of TCI states.

    Abstract: Disclosed are a method and an apparatus for performing uplink/downlink transmission and reception on the basis of a beam linkage state in a wireless communication system. A method for performing uplink transmission or downlink reception by a terminal in a wireless communication system according to an embodiment of the present disclosure may comprise the steps of: receiving configuration information for a first beam linkage state (BLS) for a first resource and a second BLS for a second resource from a base station, wherein each of the first and second BLSs includes information on a mapping relationship between reference transmission and reception and one or more target transmissions and receptions; receiving, from the base station, reference spatial parameter indication information for the reference transmission and reception with regard to the first resource; and performing the uplink transmission or the downlink reception through the second resource, on the basis of a target spatial parameter for specific target transmission and reception among the one or more target transmissions and receptions, wherein the target spatial parameter may be determined on the basis of the reference spatial parameter.

    Abstract: Disclosed are a method and device for performing beam failure recovery in a wireless communication system. In a method by which a terminal transmits an uplink or receives a downlink according to one embodiment of the present disclosure, the method comprises the steps of: transmitting a beam failure recovery request (BFRQ) to a base station on the basis of detection of a beam failure in at least one resource group from among a plurality of resource groups; receiving a response to the BFRQ from the base station; and transmitting information related to the beam failure to the base station, wherein the information related to the beam failure may indicate a specific resource group in which the beam failure is detected or the plurality of resource groups in which the beam failure is detected.

    Abstract: A method by which a terminal transmits an uplink signal in a wireless communication system, according to one embodiment of the present specification, comprises the steps of: receiving configuration information related to the transmission of the uplink signal; and transmitting the uplink signal on the basis of the configuration information. The configuration information includes a transmission configuration indicator state (TCI state). The uplink signal is transmitted on the basis of a specific panel and/or a specific spatial domain filter, according to the TCI state in which the panel ID and/or the reference RS is not configured.

    Abstract: A method for transmitting a sounding reference signal (SRS) by a terminal in a wireless communication system according to an embodiment of the present specification comprises the steps of: receiving configuration information relating to transmission of a sounding reference signal (SRS); receiving downlink control information (DCI) triggering the transmission of the SRS; and transmitting the SRS. The SRS is based on at least one of a first SRS and a second SRS configured in a region different from that of the first SRS, and the second SRS is transmitted on the basis of a configuration relating to the timing of transmission of the first SRS.
