1. A method for maintaining a plurality of network allocation vectors (NAVs) in a wireless local area network, the method comprising:receiving, by a first station (STA) from a second STA, a first frame including a receiver address (RA) field indicating a first type STA, wherein the first type STA is an interference station included in a same basic service set (BSS) of the first STA;
setting, by the first STA, a first type NAV based on a duration information included in the first frame;
receiving, by the first STA from a third STA, a second frame including an RA field indicating a second type STA, wherein the second type STA is a non-interference station included in a different BSS of the first STA; and
setting, by the first STA, a second type NAV based on a duration information included in the second frame,
wherein a data frame is transmitted by the first STA based on the first type NAV or the second type NAV,
wherein the method further comprises;
determining whether the first type STA or second type STA indicated by the RA of the first frame or the second frame is the interference station or the non-interference station based on interference/non-interference (I/NI) station lists generated in advance, wherein the interference station list of the I/NI station lists includes at least one station that transmits a response to the first frame within a preset time, and the non-interference station list of the I/NI station lists includes at least one station that transmits the response to the first frame outside the preset time.
