Abstract:
Disclosed are an apparatus and a method for simultaneously multiplexing and transmitting a broadband traffic and a machine-to-machine traffic or an ultra-reliable low latency communication traffic using the same resource. That is, according to the present invention, it is possible to enhance efficiency of resources when an eMBB traffic and an mMTC traffic or an uRLLC traffic are multiplexed, by spreading and transmitting intermittent data generated in an MTC terminal with superimposition on a subcarrier resource allocated to an eMBB terminal without reservation on a time axis while sharing a high-speed data resource in an OFDMA system and transmitting an uRLCC terminal requiring a short transmission latency time with superimposition on one symbol on a frequency axis.
