1. A method performed by a station (STA) of a wireless local area network (WLAN) system, the method comprising:
receiving a trigger frame from an access point (AP),
wherein the trigger frame includes a common information field and a user information field,
wherein the common information field has a value that identifies uplink bandwidth for all STAs associated with the AP, including the STA,
wherein the user information field includes an association identifier (AID) subfield,
wherein based on the AID subfield having a value recognizable by all the STAs associated with the AP, the user information field further includes an uplink bandwidth extension subfield having a value that identifies an extension of the uplink bandwidth identified by the value in the common information field,
wherein the user information field is contiguous to the common information field; and
transmitting a trigger based physical protocol data unit (TB PPDU) in response to the trigger frame.
