transmitting an HE RTS or HE CTS PPDU that is addressed to an AP shall not set the TXVECTOR parameter UPLINK_FLAG to 1. Otherwise, the 3rd party STA can ignore the HE RTS or HE CTS PPDU because it may enter a doze state as specified in 25.13.1 (Intra-PPDU power save for HE STAs). Change the second paragraph of sub-clause 25.11 as the following: "The Uplink Flag is carried in the TXVECTOR parameter UPLINK_FLAG of an HE SU PPDU, HE extended range SU PPDU, and HE MU PPDU and is set as follows: --A STA transmitting an HE PPDU that is addressed to an AP and does not contain a control frame shall set the TXVECTOR parameter UPLINK_FLAG to 1 --A STA transmitting an HE PPDU that is addressed to an AP and contains a control frame shall set the TXVECTOR parameter UPLINK_FLAG to 0" The RTS and CTS frames can be carried in the HE PPDU format (e.g., an HE extended range SU PPDU). Also, the TXVECTOR parameter TXOP_DURATION can be set to all 1s. In such case, for updating the NAV from the MAC header of the RTS and CTS frames, 3rd party STA shall not ignore the RTS or CTS frames carried in the HE PPDU.
