1. A method used in a wireless local area network (WLAN) system, the method comprising:
transmitting, by a first station (STA), first information related to a maximum value of a hybrid automatic repeat request (HARQ) index supported by the first STA and second information related to a time limit related to the HARQ index, the HARQ index being used for an HARQ operation of the first STA and the time limit being used for a maximum storage time of an HARQ buffer related to the HARQ index;
performing, by the first STA, association with a second STA based on the first information and the second information; and
receiving, by the first STA, third information related to a maximum value of an HARQ index supported by the second STA,
wherein the HARQ operation of the first STA is performed based on a first value that is a smaller value of the maximum value of the HARQ index supported by the first STA and the maximum value of the HARQ index supported by the second STA.
