Claim 18:
19. An apparatus of an extremely high-throughput (EHT) Access Point station (AP), the apparatus comprising: processing circuitry; and memory, the processing circuitry configured to:
encode for transmission to an EHT station (EHT STA), a frame carried in an EHT Multi-User (MU) Physical-layer Protocol Data Unit (PPDU) (EHT MU PPDU) soliciting a response;
calculate a duration of a non-high-throughput PPDU (non-HT PPDU) containing a control response frame sent at a primary rate; and
decode a PPDU carrying the control response frame received from the EHT STA, the received PPDU comprising:
a high-efficient (HE) single-user (SU) PPDU (HE SU PPDU) when a transmit time of the HE SU PPDU would be less than the calculated duration of the non-HT PPDU or an EHT PPDU when a transmit time of the EHT PPDU would be less than the calculated duration of the non-HT PPDU; or
a non-HT PPDU when the transmit time of the HE SU PPDU would not be less than the calculated duration of the non-HT PPDU and when the transmit time of the EHT PPDU would not be less than the calculated duration of the non-HT PPDU.
