Apparatus and method for operating resource in wireless local area network system supporting multi-user transmission scheme

A method of a second device in a wireless local area network (WLAN) system supporting a multi-user transmission scheme, the method comprising:

• receiving a signal including information related to a number of resource allocation request messages to be accepted by a first device at a timing point and information related to each of second devices in which a resource allocation request message is to be transmitted at the timing point,
• wherein the resource allocation request message is to be accepted if the first device is capable of allocating a resource to each of the second devices at the timing point.

A first device in a wireless local area network (WLAN) system supporting a multi-user transmission scheme, the first device comprising:

• a transceiver configured to transmit a signal including information related to a number of resource allocation request messages to be accepted by the first device at a timing point and information related to each of second devices in which a resource allocation request message is to be transmitted at the timing point,
• wherein the resource allocation request message is to be accepted if the first device is capable of allocating a resource to each of the second devices at the timing point.

A second device in a wireless local area network (WLAN) system supporting a multi-user transmission scheme, the second device comprising:

• a transceiver configured to receive a signal including information related to a number of resource allocation request messages to be accepted by a first device at a timing point and information related to each of second devices in which a resource allocation request message is to be transmitted at the timing point,
• wherein the resource allocation request message is to be accepted if the first device is capable of allocating a resource to each of the second devices at the timing point.
