4.25 Duplex Connections, FCC 15.323(c)(10):
An initiating device may attempt to establish a duplex connection by monitoring both its
intended transmit (Tx) and receive (Rx) time and spectrum windows. If both the
intended transmit and receive time and spectrum windows meet the access criteria,
then the initiating device can initiate a transmission in the intended transmit time and
spectrum window. If the power detected by the responding device can be decoded as a
duplex connection signal from the initiating device, then the responding device may
immediately begin transmitting on the receive time and spectrum window monitored by
the initiating device.
Measurements are made in accordance with ANSI C63.17 sub-clause 8.3. Test setup is
shown in section 3.3 Figure 3.3.1.
