Claim 7:
8. A first station (STA) used in a wireless local area network (WLAN) system, the first STA comprising:
a transceiver to transmit and receive a radio signal; and
a processor connected to the transceiver,
wherein the processor is configured to:
transmit 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;
perform association with a second STA based on the first information and the second information; and
receive 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.
