Abstract
A method in a wireless local area network (WLAN) includes receiving, from an access point (AP) by a station (STA), a beacon frame comprising a first field related to a transmission time of a trigger frame, wherein the trigger frame includes frequency resource information to be used for an uplink multi-user (UL MU) transmission, wherein the frequency resource information to be included in the trigger frame includes at least one of first type resource information used for random access and second type resource information used for scheduled access, wherein the random access is performed by the STA based on orthogonal frequency division multiple access (OFDMA), wherein the beacon frame further comprises a second field related to whether or not the trigger frame includes the first type resource information; receiving, from the AP by the STA, the trigger frame based on the first field; determining, by the STA, UL resource to be used for the UL MU transmission based on the first type resource information and the second type resource information; and performing, by the STA, the UL MU transmission based on the UL resource.
