Physical layer short feedback

A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors of a high efficiency (HE) station (STA), the instructions to configure the one or more processors to:

• decode a trigger frame from a HE access point (AP), the trigger frame comprising a trigger type subfield, the trigger type subfield indicating a feedback report poll trigger type, a feedback type subfield, the feedback type subfield indicating a resource request feedback type, and an association identification (AID);
• determine a resource unit (RU) for the HE STA to transmit feedback to the HE AP based on the AID, wherein the RU comprises a set of subcarriers of a HE long-training field (LTF)(HE-LTF) of a physical layer (PHY) protocol data unit (PPDU);
• encode a feedback response in accordance with the resource request feedback type for transmission on the set of subcarriers indicated by the RU;
• and
• configure the HE STA to transmit the PPDU comprising the HE-LTF.

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

• memory;
• and processing circuitry couple to the memory, the processing circuitry configured to:
• encode a trigger frame for a HE stations (STAs), the trigger frame comprising a trigger type subfield, the trigger type subfield indicating a feedback report poll trigger type, a feedback type subfield, the feedback type subfield indicating a resource request feedback type, and an association identification (AID), the AID indicating resource units (RUs) for the HE STAs to transmit feedback to the HE AP, wherein the RUs indicate sets of subcarriers of HE long-training fields (LTF)(HE-LTFs) of physical layer (PHY) protocol data unit (PPDUs), and refrain from encoding RU fields;
• configure the HE AP to transmit the trigger frame to the HE STAs;
• and
• decode feedback responses from the HE STAs in accordance with the resource request feedback type on corresponding sets of subcarriers indicated by the RUs.
