Abstract:
1. An apparatus for transmitting data in a wireless communication system, the apparatus comprising: a data processor configured to generate modulation symbols by coding information bits and by constellation-mapping the coded information bits, the modulation symbols being transmitted via a subframe including a first slot and a second slot following the first slot, each of the first slot and the second slot including a user data modulation symbol not carrying a reference signal and a reference modulation symbol carrying a reference signal, the first slot being transmitted via a first frequency band, the second slot being transmitted via a second frequency band; a transmission (TX) processor configured to: a plurality of antennas configured to transmit the subframe, wherein the reference signal includes at least one of Data deModulation Reference Signal (DMRS) and Sounding Reference Signal (SRS), wherein the SRS is only included in a last modulation symbol of the second slot, and wherein the DMRS is included in the first slot and the second slot.
