14. A wireless communication device comprising:

at least one processor; and

at least one memory communicatively coupled with the at least one processor and storing processor-readable code that, when executed by the at least one processor, is configured to:

transmit a first packet carrying basic service set (BSS) information for a BSS managed by the wireless communication device, the BSS information indicating that wireless stations (STAs), in order to associate with the wireless communication device to join the BSS, must, while thereafter operating in the BSS:

support restricted target wake time (r-TWT) operation in the BSS; or

perform a request-to-send (RTS)/clear-to-send (CTS) exchange when attempting to acquire any TXOP that exceeds a threshold duration;

receive a second packet from a wireless STA that indicates that the wireless STA will support the r-TWT operation in the BSS or perform an RTS/CTS exchange when attempting to acquire any TXOP that exceeds the threshold duration; and

associate with the wireless STA in accordance with the reception of the second packet indicating that the wireless STA will support the r-TWT operation in the BSS or perform the RTS/CTS exchange when attempting to acquire any TXOP that exceeds the threshold duration.
