Feedback parameters required by link adaptation

An apparatus of a high efficiency (HE) station (STA) (HE STA) comprising memory;

• and processing circuitry coupled to the memory, the processing circuity configured to:
• encode an aggregated control subfield of a high throughput (HT) Control field to signal one or more of:
• a request to use dual carrier modulation (DCM),
• a request to use a particular resource unit,
• an uplink (UL) power headroom indication, and
• an indication that the HE STA is using a minimum transmit power for a current modulation and coding scheme (MCS);
• and
• configure the HE STA to transmit a HE-PPDU including the HT control field.

A method for a high efficiency (HE) station (STA) (HE STA), the method comprising:

• encoding an aggregated control subfield of a high throughput (HT) Control field to signal one or more of:
• a request to use dual carrier modulation (DCM), and
• a request to use a particular resource unit,
• an uplink (UL) power headroom indication, and
• an indication that the HE STA is using a minimum transmit power for a current modulation and coding scheme (MCS);
• and
• configuring the HE STA to transmit a HE-PPDU including the HT control field.

An apparatus of a high efficiency (HE) station (STA) (HE STA) comprising memory;

• and processing circuitry coupled to the memory, the processing circuity configured to:
• decode an aggregated control subfield of a high throughput (HT) control field to identify one or more of:
• a request to use dual carrier modulation (DCM),
• a request to use a particular resource unit,
• an uplink (UL) power headroom indication, and
• an indication that the high throughput (HT) Control field was transmitted using a minimum transmission power for a current modulation and coding scheme (MCS);
• and
• communicate over a network based on the decoded request or indication.
