1. A method by a station (STA) for orthogonal frequency-division multiple access (OFDMA) in a wireless local area network (WLAN), the method comprising:

  • sending, to a network controller, information regarding at least one of scheduling transmissions for the STA, readiness of transmission, and preference of transmission;

    receiving, from the network controller, a signaling of control parameters, the control parameters determining transmission resources for OFDMA communications of the STA; and

    exchanging, between the STA and an access point (AP), OFDMA communications for at least one of downlink and uplink transmissions in accordance with the control parameters, wherein the OFDMA communications exchanged between the STA and the AP are synchronized with one or more other STAs in accordance with the control parameters,wherein the signaling is received in an OFDMA sub-header of a media access control (MAC) data frame, and wherein the OFDMA sub-header is dedicated as an OFDMA control field for carrying OFDMA control information to STAs.
