Abstract:
1. A multi-carrier transmitting apparatus for providing a multicast service in a base station using a multi-input and multi-output (MIMO) scheme, comprising: a mapping unit configured to map first data, to first and second service, and second data different from the first data, to first and second antennas, respectively; a Radio Frequency (RF) processor configured to convert the first data mapped to the first antenna into a first transmission-band RF signal of a carrier corresponding to the first data, and the second data mapped to the second antennas into a second transmission-band RF signal of a carrier corresponding to the second data, respectively; and an antenna mapping unit, configured to transmit the first transmission-band RF signal through the first antenna, and the second transmission-band RF signal through the second antenna, respectively, wherein the second data is a unicast signal.
