Disclosed are method and apparatus for transmitting/receiving audio/video content data in wireless access networks. The method comprises the steps of: encoding the audio/video content data into a basic stream having a first level of quality and an advanced stream, combination of the basic stream and the advanced stream has a second level of quality higher than the first level of quality; and transmitting the basic stream and the advanced stream with a first power and a second power lower than the first power on antennas, respectively. With the method and apparatus of the invention, the low SINR users are able to maintain the low data rate receiving the basic stream and the high SINR user can receive both the basic stream and advanced stream from two logical channels.
