摘要：
A method is provided for applying frequency domain multiplexing of unicast and multicast services on a single carrier, such that both services can operate at the same time, and may be received with the same RF front end and A/D converter. In order to reduce subcarrier interference between unicast and multicast tones a guardband is introduced between the unicast and multicast bands, where the guardband can be fixed or variable within a sub-frame. Also disclosed is a device and computer program product operable with the device.
