Abstract
When an AP detects a collision between a neighbor BSS and a BSS color in a wireless LAN system, the AP can inform an STA of the same through information indicating whether the BSS color is disabled, and set and transmit a TXOP_duration field of a transmitted frame to a specific value differentiated from a normal duration value in order to prevent an erroneous NAV setting of the STA.
