1. An apparatus of a high-efficiency (HE) access point (AP), the apparatus comprising:

  • memory; and

    processing circuitry coupled to the memory, the processing circuitry configured to;

    encode a HE physical layer convergence protocol (PLCP) protocol data unit (PPDU), the PPDU comprising a plurality of HE signal (HE-SIG) fields, wherein the plurality of HE-SIG fields are to be transmitted on separate 20 MHz sub-channels of a plurality of 20 MHz sub-channels,wherein each HE-SIG field comprises a schedule type field and a station list field, wherein a value of the schedule type field indicates a list of sub-channel allocation assignments, andwherein the station list field comprises multiple station fields, wherein each station field of the multiple station fields comprises an association identification (AID), wherein the list of sub-channel allocation assignments and a position of a station field in the multiple station fields together identify a frequency allocation for a HE station identified by the AID of the station field; and

    generate signalling to cause the HE PPDU to be wirelessly transmitted by the HE AP within the plurality of 20 MHz sub-channels, wherein the plurality of HE SIG fields of the HE PPDU are concurrently transmitted on an associated one of the plurality of 20 MHz subchannels.
