Classification: CPC H | IPC H

Claim 12:
13. A non-transitory computer-readable storage medium that stores instructions for execution by processing circuitry of an extremely high-throughput (EHT) station (STA), wherein in response to a frame carried in an EHT physical layer conformance procedure (PLCP) protocol data unit (PPDU) soliciting a control response frame, the processing circuitry is configured to:
calculate a duration of a non-HT PPDU containing the control response frame sent at a primary rate; and
encode a high-efficient (HE) single-user (SU) PPDU (HE SU PPDU) for transmission to carry the solicited 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
encode an EHT PPDU for transmission to carry the solicited control response frame when a transmit time of the encoded EHT PPDU is less than the calculated duration of the non-HT PPDU,
wherein the processing circuitry is configured to encode a non-HT PPDU for transmission to carry the solicited 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.
