Classification: CPC H | IPC H

Claim 0:
1. An apparatus of an extremely high-throughput (EHT) station (STA), the apparatus comprising: processing circuitry; and memory,
wherein in response to a frame carried in an EHT Multi-User (MU) physical layer conformance procedure (PLCP) protocol data unit (PPDU) (EHT MU PPDU) soliciting a response, the processing circuitry is configured to:
calculate a duration of a non-HT PPDU containing a control response frame sent at a primary rate; and
encode either a high-efficient (HE) single-user (SU) PPDU (HE SU PPDU) for transmission to carry the control response frame when a transmit time of the encoded HE SU PPDU is less than the calculated duration of the non-HT PPDU or an EHT PPDU for transmission to carry the control response frame when a transmit time of the encoded EHT PPDU is less than the calculated duration of the non-HT PPDU; and
encode a non-HT PPDU for transmission to carry the control response frame when the transmit time of the encoded HE SU PPDU would not be less than the calculated duration of the non-HT PPDU and when the transmit time of the encoded EHT PPDU would not be less than the calculated duration of the non-HT PPDU.
