Title:
APPARATUS FOR SIMULTANEOUSLY MULTIPLEXING AND TRANSMITTING BROADBAND TRAFFIC AND MACHINE-TO-MACHINE COMMUNICATION TRAFFIC OR ULTRA-LOW-DELAY COMMUNICATION TRAFFIC USING SAME RESOURCE AND METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/179915
Kind Code:
A2
Abstract:
Disclosed are an apparatus for simultaneously multiplexing and transmitting a broadband traffic and a machine-to-machine communication traffic or an ultra-low-delay communication traffic using the same resource, and a method therefor. That is, in the present invention, intermittent data generated in an MTC terminal is spread along a time-axis and then transmitted with superimposition on a sub-carrier allocated to an eMBB terminal without reservation by sharing a high-speed data transmission resource in an OFDMA system, and is spread along a frequency-axis and then transmitted with superimposition on a single symbol with respect to a uRLLC terminal requiring a short delay time, thereby enhancing a resource efficiency when an eMBB traffic and an mMTC traffic or a uRLLC traffic are multiplexed.
