    Abstract: A method for transmitting and receiving downlink data in a wireless communication system, and a device for same are disclosed. Specifically, the method includes the steps of: receiving setting information; receiving downlink control information (DCI); and receiving a plurality of transmission occasions of the same transport block based on the DCI, wherein a repetition scheme based on time division multiplexing (TDM) is set based on the setting information, the DCI includes a time domain resource assignment field, resource allocation in a time domain for a first transmission occasion may be determined based on the time domain resource assignment field of the DCI, and the resource allocation in the time domain for a second transmission occasion may be determined based on the resource allocation in the time domain for the first transmission occasion.

    Abstract: A method for transmitting and receiving a radio signal in a wireless communication system and a device therefor are disclosed. A method for receiving, by a base station, a sounding reference signal (SRS) in the wireless communication system includes transmitting, to a user equipment (UE), configuration information for transmission of the SRS; and receiving, from the UE, the SRS transmitted based on the configuration information. The configuration information includes group hopping information and sequence hopping information for sequence hopping of the SRS. A sequence length of the SRS is based on a product of a number of candidates of the group hopping information and a number of candidates of the sequence hopping information. The number of candidates of the group hopping information and the number of candidates of the sequence hopping information are configured based on a number of neighboring cells of the base station.

    Abstract: A method for a base station to control inter-cell interference in a wireless communication system comprises: a step in which a base station receives, in a predefined physical resource region, a demodulation reference signal (DMRS) or a sounding reference symbol (SRS) from a terminal in a cell to which the base station belongs; a step of measuring interference in a resource on which the DMRS or the SRS has been transmitted, on the basis of an interference measurement method corresponding to the predefined physical resource region; and a step of determining the terminal as a victim terminal associated with the predefined physical resource region, if the intensity of the interference measured is greater than a predetermined threshold, wherein the predefined physical resource region may be a first physical resource region for an uplink data transmission in the cell to which the base station belongs, or a second physical resource region for uplink beam sweeping in the cell to which the base station belongs, the first and second physical resource regions corresponding to a physical resource region for uplink beam sweeping in a neighboring cell to which a neighboring base station belongs.

    Abstract: Disclosed is a method and apparatus for transmitting and receiving a Reference Signal (RS) performed by a User Equipment (UE) in a wireless communication system. According to the present invention, a method and apparatus includes receiving a first Dedicated Demodulation Reference Signal and a first Physical Downlink Shared Channel (PDSCH); receiving a Physical Downlink Control Channel (PDCCH) including Downlink Control Information (DCI) in relation to a configuration of the second Dedicated Demodulation Reference Signal based on the first PDSCH; and receiving the second Dedicated Demodulation Reference Signal and a second PDSCH based on the PDCCH, and the first Dedicated Demodulation Reference Signal is transmitted only on a single antenna port, and a configuration of the DCI is determined based on the maximum number of symbols to which the second Dedicated Demodulation Reference Signal is mapped.
