Apparatus, methods, and other embodiments associated with duplex mode enabling frame headers are described. According to one embodiment, an apparatus includes a transceiver and duplex logic. The duplex logic is configured to receive data to be transmitted by the transceiver to a device and generate a header for a frame. The header includes at least one bit that encodes information used to enable full duplex communication with the device. The duplex logic is configured to provide the frame to the transceiver to transmit the frame.
