A method by which a relay entity delivers a multicast/broadcast frame in a wireless LAN system, according to one embodiment of the present disclosure, includes the steps of: receiving a multicast/broadcast frame from an STA; and delivering the multicast/broadcast frame to a root access point (AP). The multicast/broadcast frame may be transmitted by the root AP in a broadcast scheme within a basic service set (BSS). In the multicast/broadcast frame transmitted in the broadcast scheme by the root AP, an address 1 (A1) field may be set to a multicast/broadcast address, an Address 2 (A2) field may be set to a medium access control (MAC) address of the root AP, and an Address 3 (A3) field may be set as a MAC address of the STA, which is a source address of the multicast/broadcast frame."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for multicasting/broadcasting in relay network of wireless LAN system","description":"The present disclosure relates to a wireless communication system and, more particularly, to a method and apparatus for multicasting/broadcasting in a relay network of a wireless LAN system.
