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.
