The present invention proposes new and various frame structures for a 5th generation (5G) communication system. In a next generation 5G system, scenarios can be classified into Enhanced Mobile BroadBand (eMBB), Ultra-reliable Machine-Type Communications (uMTC), Massive Machine-Type Communications (mMTC), and the like. The eMBB corresponds to a next generation mobile communication scenario having such a characteristic as high spectrum efficiency, high user experienced data rate, high peak data rate, and the like, the uMTC corresponds to a next generation mobile communication scenario having such a characteristic as ultra-reliable, ultra-low latency, ultra-high availability, and the like (e.g., V2X, Emergency Service, Remote Control), and the mMTC corresponds to a next generation mobile communication scenario having such a characteristic as low cost, low energy, short packet, and massive connectivity (e.g., IoT).

FIG. 2 is a diagram for explaining correlation between IMT 2020 core performance requirement for 5G and 5G performance requirement per service scenario.

FIG. 2 illustrates correlation between core performance requirement for 5G proposed by IMT 2020 and 5G performance requirement per service scenario.

In particular, uMTC service has very high restriction on Over The Air (OTA) Latency Requirement and requires high mobility and high reliability (OTA Latency: <1 ms, Mobility: >500 km/h, BLER: <10^?6).
