1. A method, comprising:

  • (a) obtaining resource allocation (RA) information by an orthogonal frequency division multiple access wireless radio station (STA) in a wireless network, wherein the RA information is indicated in a HE-SIG-B common field and a user specific field, and wherein the HE-SIG-B common field is a fixed format;

    (b) determining an operation bandwidth (BW), wherein the operation bandwidth is partitioned into predefined resource units, and wherein different operation bandwidths are partitioned into one or more HE-SIG-B channels, and wherein each HE-SIG-B channel represents a resource block of a first frequency;

    (c) determining a resource allocation using an RU look-up table (LUT) based on the RA information;

    (d) compressing the HE-SIG-B common field for full BW MU-MIMO packets; and

    (e) determining the existence of a user specific field for middle 26 tone RU of a channel of a second frequency, wherein the HE-SIG-B common field comprises a one-bit middle RU indicator indicating whether the middle 26 tone RU of an 80 Mhz is allocated;

    (f) communicating using the STA in accordance with the RA information.
