1. A method for performing a response process in a wireless local access network (WLAN) system, the method comprising:

  • transmitting, by a first station (STA), a frame requiring a response frame to a second STA;

    waiting, by the first STA, for the response frame during an ACKTimeout interval configured differently according to whether a preamble channel bandwidth type of the frame is a 1 MHz preamble type or is a 2 MHz or more preamble type; and

    determining, by the first STA, that transmission of the frame has failed and performing, by the first STA, a backoff procedure, when the ACKTimeout interval is ended,wherein the configured ACKTimeout interval is determined based on a value of an aPHY-RX-START-Delay set to a different value according to whether the preamble channel bandwidth type of the frame is the 1 MHz preamble type or is the 2 MHz or more preamble type, andwherein a preamble channel bandwidth of the response frame is set to a value equal to the preamble channel bandwidth type of the frame.
