1. A method for performing a relay operation by a relay entity of a wireless LAN (WLAN) system, the method comprising:
- receiving, from a non-access point (AP) station (STA), a probe request frame,in response to the probe request frame, transmitting, to the non-AP STA, a probe response frame comprising information that informs the non-AP STA whether the relay entity is a relay AP or a root AP,wherein the relay entity is operated as an AP for the non-AP STA,wherein when the information informs the non-AP STA that the relay entity is a relay AP, the probe response frame further comprises a medium access control (MAC) address of the root AP associated with the relay entity and service set identifier (SSID) information, andwherein the SSID information is set to be identical to an SSID of the root AP associated with the relay entity, andperforming an association process with the non-AP STA,wherein when the information informs the non-AP STA that the relay entity is a relay AP, receiving a MAC service data unit (MSDU) from the associated non-AP STA and forwarding the received MSDU to the root AP associated with the relay entity through a MAC protocol data unit (MAC PDU) of an aggregate-MSDU (A-MSDU) format frame.

Abstract
A method and apparatus for performing a relay operation in a wireless LAN (WLAN) system are disclosed. A method for performing a relay operation by an entity of a wireless LAN (WLAN) system includes: transmitting a frame including information indicating whether the entity is a relay access point (AP) or a root AP to at least one station (STA), wherein, if the entity is the relay AP, the frame further includes a Medium Access Control (MAC) address of the root AP associated with the entity.

12. A relay entity for performing a relay operation in a wireless LAN (WLAN) system, the relay entity comprising:
-
a transceiver; and at least one processor coupled with the transceiver and configured to; receive, from a non-access point (AP) station (STA), a probe request frame, in response to the probe request frame, transmit, to the non-AP STA, a probe response frame comprising information that informs the non-AP STA whether the relay entity is a relay access point (AP) or a root AP, wherein the relay entity is operated as an AP for the non-AP STA, wherein when the information informs the non-AP STA that the relay entity is the relay AP the probe response frame further comprises a medium access control (MAC) address of the root AP associated with the relay entity and service set identifier (SSID) information, wherein the SSID information is set to be identical to an SSID of the root AP associated with the relay entity, performs an association process with the non-AP STA, and when the information informs the non-AP STA that the relay entity is a relay AP, receive a MAC service data unit (MSDU) from the associated non-AP STA and forwarding the received MSDU to the root AP associated with the relay entity through a MAC protocol data unit (MAC PDU) of an aggregate-MSDU (A MSDU) format frame.
