1. A method for transmitting data in a wireless local area network (WLAN) system, the method comprising:
transmitting, by a transmitting station (STA), information on a preamble puncturing pattern to a receiving STA; and
transmitting, by the transmitting STA, data to the receiving STA through a 320 MHz band based on the preamble puncturing pattern,
wherein the preamble puncturing pattern is determined based on a unit of a first bandwidth in which clear channel assessment (CCA) is performed and a unit of a second bandwidth in which user-specific information is repeated,
wherein at least one 20 MHz subchannel is punctured in the 320 MHz band based on the preamble puncturing pattern,
wherein the user-specific information comprises first information and second information,
wherein the first information and the second information are repeated in units of the second bandwidth,
wherein the unit of the first bandwidth is 20 MHz, and
wherein the unit of the second bandwidth is 40 MHz.
