The Receiver Address (RA) of the CTS frame is copied from the
Transmitter Address (TA) field of the immediately previous RTS frame to
which the CTS is a response.
The Duration value is the value obtained from the Duration field of the
immediately previous RTS frame, minus the time, in microseconds, required
to transmit the CTS frame and its SIFS interval.

Figure 9.22: ACK Frame Format
The Receiver Address of the ACK frame is copied from the Address 2 field

is obtained from the Duration field of the previous frame, minus the time, in
microseconds, required to transmit the ACK frame and its SIFS interval.
