Methods and apparatus for resource allocation for multiple user transmission in a High Efficiency WLAN (HEW) are described. An embodiment is a method for transmitting a Physical layer Protocol Data Unit (PPDU) by an access point (AP) to a plurality of stations (STAs). The method may include transmitting, to the plurality of STAs, a preamble including a High-Efficiency SIGNAL (HE-SIG) field, an HE-Short Training Field (HE-STF) field and an HE-Long Training Field (HE-LTF) field in the PPDU on a transmission channel; and transmitting, on the transmission channel, a data field including a group addressed frame transmitted in a first subchannel among a plurality of subchannels into which the transmission channel is divided.
