A method and apparatus for providing a user input back channel (UIBC) in an audio/video (AV) source device and an AV sink device communicating according to a wireless fidelity (Wi-Fi) display (WFD) standard is provided. The method includes: setting up an AV control session and an AV data session between the AV source devices according to the WFD standards; enabling the UIBC from the AV sink device to the AV source device by using the AV control session; and transmitting a user input from the AV sink device to the AV source device through the UIBC.
